Supported Environments

For information on supported environments, see the VMware Interoperability Matrix.

Known Issues

The following known issues have been discovered through rigorous testing. The list of issues below pertains to this release of vSphere Data Protection only.

VMware issue

  • Snapshot removal failed even though the "Create Snapshot" task returned a valid snapshot.

    Occasionally, backups may fail with the "Snapshot Removal Failed" error. This is due to a VMware defect where the snapshot removal is denied by the vCenter Server, even if the snapshot creation was successful.

    Workaround: Manually remove the snapshot from the virtual machine using the Snapshot Manager and then resubmit the backup job.

  • Canceling a backup job leaves disks attached to the VDP virtual appliance and snapshots are not removed.

    If a request to cancel a running backup is received and the proxy cannot complete the operation within two minutes, the agent ends the proxy (this is by design), which may leave snapshots on the VM and any hot added disks attached to the VDP appliance.

    This is a known proxy issue, which will be fixed in a future release.

vCenter issue

  • Canceling a manual restore to an existing VM causes "Consolidation Needed" on the existing VM.

    Virtual machine disk consolidation is the root of the failure, and this will cause further backups to fail. Clean up needs to be implemented for the canceled restore operations.

    Workaround: From the vCenter, select and right-click the existing VM and select Snapshot > Consolidate. Note that it is possible to create a vCenter Server alarm to notify administrators when a VM is running from a snapshot. See VMware KB article 1018029 for details.

    1. Select the existing VM.
    2. Right-click the VM and select Snapshot > Consolidate.

License issue

  • Licensing: The VDP Advanced license expiration date is always None if the VDP Advanced appliance is registered to a non-English vCenter.

    When a VDP Advanced Appliance is registered to a non-English vCenter, the plug-in will always display the expiration date as "None" for evaluation licenses. Once the appliance is registered to an English vCenter, the issue no longer exists.

Interoperability issues

  • In a VSAN environment, the image-level restore to original location operation is allowed, but the disk-level restore to original location operation is grayed out, after migrating the entire virtual machine to another datastore.

    Workaround: Either restore the entire VM with an image-level backup or restore the disk level backup as a new disk on the original VM.

  • Failed to import VDP disks stored in the vsanDatastore.

    In a VSAN environment, VMware creates two folders in the vsanDatastore for each VM. One is named after the virtual machines name and the other is named after the virtual machines UUID. All the VM files are saved in the UUID folder. In the VM name folder, symbolic links point to the files in the UUID folder. A failure occurs when a user attempts to import VDP disks from an old appliance using the symbolic links in the VM name folder.

    Workaround: Storage vMotion the disks out of the vSAN datastore to a regular datastore.

Installation Issue

  • During VDP installation, if the user clicks Previous on the vCenter Server registration screen with no values being entered, the system fails to register with the vCenter Server and the installation fails.

    Workaround: Re-install VDP using the instructions in the "VDP Installation and Configuration" chapter of the vSphere Data Protection Administration Guide.

Single VMDK issues

  • Existing thick eager-zeroed disks change to thick lazy-zeroed disks post expansion.

    When extending a VMDK which is thick eager-zeroed, the extended part is only thick lazy-zeroed. If you need to grow your VMDK and you require your VMDK to be thick eager-zeroed, then use the parameters outlined in the following VMware blog:


  • A single VMDK restore from a backup of a retired or replicated client to an existing VM is creating a new VM on the vCenter Server.

    When a user creates and replicates a backup from a different source appliance to a new appliance, two restore points exist: one from the backup job and the other as a result of the replicated client. If the virtual machine is deleted or removed from the vCenter Server inventory, a timestamp is appended to the backup that was created earlier. The user should now see two restore points: the backup of a replicated client and the backup of the retired (deleted or removed) client.

    Using the Restore Backup wizard, the user selects a single VMDK to be restored to an existing virtual machine. Once the restore job begins, rather than adding a new disk to the existing VM, the VDP Appliance creates a new VM in the vCenter inventory. The expected behavior is the new disks are added to an existing VM rather than creating a new VM.

  • Incorrect behavior of the VDP Advanced Appliance when more disks are added to the same SCSI slots.

    The VDP Advanced Appliance initiates a restore operation with the same SCSI IDs on the same existing VM assigned to two different restore points. In addition, the Summary page incorrectly indicates that two new virtual disks will be added. The Restore operation completes successfully without informing the user that only the first single disk was added, and the second disk simply replaced the first disk.

General VDP Appliance Issues

  • If a thin provisioned VDP reaches datastore capacity, then even after freeing up the datastore and creating more space, integrity check errors occur on the VDP.
  • vCenter events do not generate during initial configuration if the user modifies the VDP hostname or IP address.

    Workaround: Monitor the reconfiguration events on the VDP Appliance console.

  • Upon successful upgrade to VDP 5.5.x, the user will see two plug-ins listed on the left pane of the vCenter.

    When the upgrade installs successfully, two plug-ins appear on the left pane of the vSphere Web Client. VDP versions 5.1 and earlier are managed using the vSphere Data Protection plug-in. VDP version 5.5 is managed using the vSphere Data Protection 5.5 plug-in.

    NOTE: Two plug-ins also appear if a VDP Appliance version 5.5 is installed and a version earlier than 5.5 already exists.

    To remove the vSphere Data Protection plug-in, you must upgrade all VDP Appliances to VDP version 5.5 and use the plug-in manager to disable the VDP plug-in.

    Refer to the VMware vSphere Documentation Center web site for information about managing vCenter plug-ins.

  • There are broken links on the Getting Started page.

    This is a known issue and will be fixed in a future release.

  • Unable to log in to vdp-configure after the first reboot.

    There are intermittent instances where the user is unable to login to vdp-configure after the deploy-reboot cycle. No error is shown in the vdr-configure log. Clearing the browser cache and trying to log in with different browsers does not fix the problem.

    Workaround: Using a console connection, log into the VDP virtual appliance and use the following commands to manually start and stop the vdp-configure services:
    emwebapp.sh --restart

  • The VDP Appliances crashes and powers off when a thin-provisioned virtual machine is restored on a datastore with insufficient space.

    The appliance crashes because the disk that has been hot-added to the appliance has insufficient space, so placing the appliance on a different datastore would not fix the problem.

    As a best practice, before performing an ABV or restore task, check the free space availability on the datastore to ensure there is sufficient space.

  • Import Disk: The Initial Configuration wizard always allocates the default of 4 vCPUs and 4 GB RAM.

    Irrespective of imported capacity, which for VDP Advanced can be 2 TB, 4 TB, 6 TB, or 8 TB, by default, the wizard always allocates only 4 vCPU and 4 GB RAM. The import operation completes successfully, the VDP Advanced Appliance is up and running, which could cause issues later in terms of being under-provisioned for memory. The expected behavior is the Initial Configuration wizard should set the default to the minimum Memory based on the capacity being imported, as it does when performing a fresh installation of VDP Advanced.

    Adjust the amount of allocated memory based on the information below. The minimum amount of memory per VM depends on the capacity.

    • 2 TB capacity--6 GB memory
    • 4 TB capacity--8 GB memory
    • 6 TB capacity--10 GB memory
    • 8 TB capacity--12 GB memory
  • Slow response from the VDP User Interface

    After using the VDP Appliance 5.5.x for several days, the UI performance is significantly slower than when the appliance was first deployed. Specific areas where performance is an issue are as follows:

    • Initial connection to VDP after logging in to the vCenter
    • Creating a new backup job
    • Expanding the list of Microsoft Exchange servers on the Backup wizard
    • Editing existing backup jobs
    • Refreshing the Restore tab
    • Browsing into a backup on the Restore tab

    In general, the time to load data depends on the number of jobs you are running concurrently.

    Workaround: Restart the web services on the VDP Appliance using the following command:

    emwebapp.sh --restart

  • Backups, restores to original location, and restores to new location operations work as expected on datastores with Chinese names. However, if a target virtual machine is on that datastore as a new disk, the restore to new location operation fails on datastores with Chinese names.

    This is a known image proxy issue, which will be fixed in a future release.

  • Unable to access destination virtual machines for a single disk restore when multiple restore points are selected.

    Restore points are created for two different virtual machines (for example, VM-1 and VM-2). On the Restore tab, a restore point of VM-1 is selected at the image level and a restore point of VM-2 is selected at the disk level. For the single disk restore point, the VMs are not visible in the hierarchy.

  • A password change on a configured vCenter Server is not allowed on the VDP Appliance, even after the vCenter Server password has expired.

    The VDP-Configure application does not allow a password change for the configured vCenter if backups are in a Running state on the server. If the user password on the configured vCenter has already expired, no tasks are posted on the task console, and, consequently, the tasks cannot be canceled.

    Workaround: Perform the following steps:

    1. Wait until all the backups and tasks finish in the VDP Appliance and then change the password.
    2. Restart the VDP Appliance in the maintenance window, and then log into the VDP-Configure user interface and change the vCenter password from the VDP-Configure user interface.
  • The Retention Policy name is not updated after editing the backup job name.

    When editing a backup job and modifying the name of the job using the Create Backup Job wizard, the new name is updated in the VDP user interface. When verifying if the group name, schedule, and retention policy name are also updated with the new name, the group name and schedule are updated, but the retention policy name is not.

  • The Performance Assessment Test (PAT)result changes to Never Run when the datastore name is changed.

    In this scenario, the user opens the VDP-Configure user interface, clicks the Storage tab, selects a datastore, and clicks the Run performance analysis on storage configuration checkbox. The performance analysis test completes successfully and the results of the performance analysis are displayed correctly. If the user changes the name of the datastore, however, the performance analysis results erroneously indicate the status as Never Run.

  • It is not possible to re-enter the Storage Expansion wizard.

    If you close the browser while storage expansion is running, the application should allow the user to re-enter the Storage Expansion wizard while expansion is taking place and bring the user to the Ready to Complete screen. Currently, the user cannot re-enter the wizard.

Backup Issues

  • If a large backup job is created (~100 VMs), the backup job can take up to ten minutes to create.
  • No proper error handling when running scheduled disk backup job of a VMDK which was migrated to another datastore.

    A scheduled backup job of a VMDK completes without any errors but when the datastore location is changed to another datastore, the error occurs.

  • Backup jobs do not display on the Reports tab or the Backup tab.

    Call Technical Support.

  • Scale inventory: Create backup job fails to include all clients when creating a job for a large number of virtual machine clients.

    Intermittently (approximately one out of five attempts), when the user attempts to create a backup job of a container holding a large number of virtual machines, the VDP Advanced Appliance reports back that a few clients could not be added to the backup job.

    Workaround: Manually edit the backup job to add the few missing clients.

  • Cannot create a user name with more than 20 characters using the VMware VDP Exchange Backup User Tool.

    Workaround: Create a user name with 20 characters or less.

  • Loading clients takes a significant amount of time when editing or cloning a backup job.

    The edit or clone action of a backup job for a SharePoint server (upgraded plug-in) takes 5 to 10 minutes to load clients. In addition, some delay occurs when loading clients for Microsoft Exchange and SQL servers that were created before an upgrade.

    This is a known issue that will be fixed in a future release.

Restore Issues

  • If a virtual machine is deleted during a VDP restore operation, the virtual machine is not properly removed from the VDP inventory. This causes an error when editing the backup jobs that included the deleted virtual machine as source. Additionally, if a virtual machine is created with the same name, attempts to add the virtual machine to a backup job will fail.

    Workaround: As a best practice, avoid deleting virtual machines during restore operations. If this error does occur, create the virtual machine with a new name and add it to a new backup job.

  • When a larger size VM (with multiple disks) is restored over an existing smaller size VM (with one disk), the restore job completes but only one disk is actually restored. The VDP Appliance does not display this activity with an error message (for example: "not enough destination disks"). As a result, there is a possibility of data loss if all the disks are not restored and the user is not aware of it because no VDP event is generated.

    In order to perform the disk compatibility check, the disk size on the target machine and the size of the disks in the backup being restored must be known.

  • Deleted disks are skipped when restoring to original location.

    If the target VM no longer has the same disk footprint as the original VM that was backed up (if the disks have been removed or deleted from the VM), performing a "Restore to original location" operation, after selecting a restore point timestamp in the Restore pane, will silently fail to restore the missing disk of the VM.

    Workaround: Restore the disk to its original location after manually adding the missing disk to the VM. Ensure the disk is the same size as it was when the VM was backed up. If this workaround fails, restore the disk to a new location to create a new VM. When the restore task completes, detach the restored disks from the new VM and attach them to the required VM using the information in "Detaching and Reattaching Storage" of the vSphere Data Protection Administration Guide.

  • Restore fails when attempted to restore as new VM using previous name of the renamed VM.

    When the user creates a backup job for a VM, selects the restore point, and enters the old name of the renamed VM in the Restore to New Location field, the restore fails with the following message: Unable to restore VM for restore point. The datastore path already exists.

  • Attach existing storage to VDP: Restore pane shows multiple entries with the exact same name if import is done more than once against the same vCenter Server.

    When a user performs more than one import in a single vCenter Server, the exact same name appears in the Restore pane for both restore point entries.

  • "Set Restore Option" during restore rehearsal is blank if you are not connected to the VDP Appliance.

    On the Set Restore Options page of the Restore a backup wizard, you can specify to where you want the backup restored (Restore to Original Location or Restore to New Location). The Set Restore Options page is blank, however, if you are not connected to the VDP Appliance.

    Workaround: Connect to the VDP Appliance to use the Restore a backup wizard and its options.

  • Five to eight manual restores take 10 minutes or longer to submit and a client is missed.

    Consistently, it takes 10 minutes to submit 5, 6, and 8 manual restores. In addition, the Web client fails to include one client from the overall number of restores. As a result, it is not possible to collect rates for 8 manual restores in parallel, since one of the jobs does not get submitted or times out.

  • The SCSI ID that is already assigned to a device is listed in the Restore Wizard. The user is allowed to select the assigned SCSI ID when restoring an individual virtual machine disk (VMDK).

    Workaround: Do not select the SCSI slot that is assigned to any existing device as the target for disk restores.

  • Failure to create disk restore jobs when SCSI Controller ID numbers are not continuous on the target virtual machine (VM).

    For example, if the target VM has SCSI Controller 0 and 3, and the user tries to restore a disk to an empty slot on SCSI Controller 3, the operation fails with an error.

    Workaround: Either restore the disk to SCSI Controller 0 or make sure the target VM has all the SCSI Controllers starting with 0 to the one you want to restore (0, 1, 2, 3) (56887) ABV: Scheduled verification tasks get stuck at 92% if the host becomes disconnected during the operation.

    If the destination host to which the temporary virtual machine is being restored gets disconnected, the scheduled verification task gets stuck at 92%.

    Workaround: Manually cancel the task and, if the task cannot be cancelled, restart the vCenter web services or the VDP Appliance using the following command:

    emwebapp.sh --restart

  • SCSI ID: The disk restore of a retired or a replicated VM onto an existing VM creates a new VM.

    When a user initiates a SCSI ID restore of retired virtual machine disks onto an existing VM, instead of adding the disks to the selected VM, it creates a new VM by attaching all the selected disks to it.

    Workaround: After performing a restore, manually attach the restored disk to its original (existing) virtual machine.

File Level Recovery (FLR) Issue

  • Post-import, FLR login fails for the virtual machines that were backed up before import.

    File level recovery (FLR) is not supported for the restore points which have been imported from previously-used VDP disks (as described in "Attaching Existing Storage in the vSphere Data Protection Administration Guide). This limitation does not apply to restore points that are created for any subsequent backups performed after the import.

Replication Issues

  • Client cache does not support multiple replication jobs.

    Multiple replication jobs for the same MS-App client causes errors during execution if they are scheduled for the same time.


    • Ensure that the start time for the replication jobs are staggered.
    • Do not put the same client in multiple replication jobs.
  • Multiple replication jobs for different VMs run in series and not in parallel.

    The replication activity for multiple virtual machines should process in parallel. The sequential behavior occurs only when another replication job with the same clients is already running. In this case, the client replication task waits for the already-running replication job to complete.

  • Replicated backups cannot be replicated again.

    The Replication wizard does not support replicating backups that have already been replicated from a different source server. Clients or restore points that have already been replicated from a different source server do not appear as available in the Create | Edit | Clone replication job wizard.

  • Unable to replicate backups from imported disks.

    Imported backups (that is, backups that were created with a previous appliance from where disks were imported to a new appliance) cannot be replicated. You can only replicate VM clients that have a current VM client registration.

    This is a known limitation of storage import and will be fixed in a future release.

Microsoft Application (MS App) Issues

  • The loading time of individual databases for an MS-App client can take longer than expected.

    After invoking the MS-App Backup wizard, browsing individual databases on the Backup Targets page takes longer than usual on the VDP Advanced Appliance.

  • Selecting a folder for SharePoint restore does not select all existing subfolders in the browsing tree.

    When selecting any folder for a Microsoft SharePoint restore, all existing subfolders do not display as available for selection. Although the subfolders do not display as available for restore, the restore process successfully restores all the subfolders in the folder.

  • Microsoft SharePoint redirected restore job fails for the database if the IP address is used as an alias instead of the server name.

    Backing up to the original location with the overwrite option works correctly. The backup fails only when running a redirected restore when the IP address is used instead of the server name.

    Workaround: Use the server name when creating an alias.

  • A Microsoft SharePoint redirected restore job displays as successful, even when some databases fail to restore.

    When restoring many databases or an entire SharePoint farm, some problematic databases may fail. Even though some of the databases fail, the restore job reports that the job is successful. This could result in lost data. The database backup fails only when running a redirected restore when the IP address is used instead of the server name when creating an SQL alias.

    Workaround: Use the server name when creating an alias.

  • Out-of-date sources for a failed or cancelled Application database backup displays incorrect count.

    The difference between the sources count and the out-of-date sources count is common for Microsoft SQL and Exchange application database backups.

  • On Microsoft Exchange clients, there are many warning messages in the avagent log that print frequently and fill up the logs.

    The Microsoft Exchange client is left registered with two VDP Advanced Appliances in the vCenter, which is causing this issue.

Storage Management Issue

  • Backups to Data Domain systems fail due to the image proxy timing out.

    There is a flag that determines the timeout value. The default timeout value is 300 seconds (5 minutes). The workaround is to set the flag to a value different from the default timeout value, but there are no professional services available for VDP. Contact VMware Global Support Services (GSS) for assistance with changing this value.

Automatic Backup Verification (ABV) Issues

  • ABV: The Clients report does not filter for "is within the last" 60 minutes.

    The minutes filter is not working as expected. Though the Clients report does not filter for "is within the last" 60 minutes, it does report for the last 1 hour. This issue exists for both backup jobs and backup verification jobs.

  • ABV: Verification job fails after renaming the datastore.

    This error can occur if you rename or move the destination datastore outside of VDP.

    Workaround: Edit the verification job and select the renamed or moved destination datastore as the new destination. For instructions, refer to "Editing a Backup Verification Job" in the vSphere Data Protection Administration Guide.

  • ABV: Verification job fails to initiate when destination path for host is changed.

    Workaround: Edit the verification job and select the appropriate destination path when you perform the verification job.

  • ABV: The status of scheduled verification job activity cannot be determined if the destination is in maintenance mode.

    An error message displays, but there is no log activity.

  • ABV: An on-demand verification job is not initiated if the last backup was not successful.

    The following error is observed on an ABV job if the last backup was not successful:
    Error: "Unexpected error with NO error code, refer to logs."
    The user is not made aware of the problem and the logs do not contain useful information.

  • Improper error messages are reported if the Verification job failed because of connection issues due to Data Domain.

    The backup cannot be restored and the Verification job fails because the VDP Appliance cannot talk to the Data Domain. It is expected for the Verification job to fail; however, the proper error message does not display and the user does not know the root of the failure.

  • For automatic backup verification (ABV) jobs, cancelling a running ABV task activated from the Web Client does not remove the VDP_Verification virtual machine from the datastore.

    When browsing the datastore specified as the destination for the new VM, the VDP_VERIFICATION_xxxx VM is still present on the datastore, even after refreshing the browser.

  • The host is not compatible with the virtual machine that it needs to restore and leaves behind orphaned virtual machines in the vCenter inventory.

    Automatic backup verification (ABV) jobs that are incompatible with the host will fail, and failed ABV jobs leave behind orphaned virtual machines in the vCenter inventory.

    Workaround: Manually delete or unregister the temporary virtual machines that remain in the vCenter or datastore inventory.

  • ABV job fails to be submitted after the most recent backup has been deleted.

    If the most recent backup (backup-N) is deleted, the user is unable to verify backups that occurred before backup-N.

    Workaround: Create a new backup. With the new backup, the user will not encounter issues in verifying future backups.

Granular Level Recovery (GLR) Issues

  • A granular level restore (GLR) on a Microsoft Exchange server is allowed for clients that do not have the VDP Advanced Plug-in for Exchange GLR installed.

    The GLR operation is now blocked when the VDP Advanced Plug-in for Exchange GLR is not installed.

  • When performing a granular level restore (GLR) on a Microsoft Exchange server, the destination mailbox field should be optional.

    When the user restores to a single mailbox, the default value is to restore to the original location. The user interface does not allow an empty value for this field. If the user selects "restore to alternate location," every mailbox from that backup is restored to a single mailbox.

    Restoring a mailbox to its original location and restoring the original path to a different client is supported and working as designed. The inability to restore multiple mailboxes to their original locations is a known issue.

Resolved Issues

The following issues have been resolved:

  • Image backup and VMDK backup job of VM with SCSI bus-sharing enabled is allowed, but fails, and the job task does not appear in the vCenter.

    The following VMware knowledge base article states that snapshots are not supported for SCSI bus sharing VMs:

    Fixed in 5.5.6 Update 1 Release

  • Backups that are 2 TB or larger in size fail silently and falsely report as successful on Windows virtual machines with disk.EnableUUID=true.

    This issue is deferred to VDDK 5.5.U1 for a fix. Windows support for VMs greater than 2 TB is dropped from the product until the issue is resolved.

  • File Level Recovery (FLR) does not work on any VM running Windows 2012 and Windows 8 with a second disk.
  • The VDP Appliance plug-in installers cannot be downloaded using the latest Google Chrome browser version.

    Fixed in 5.5.6 Update 1 Release.

  • The "Allow database overwrite" option is not set to "true" in the Microsoft Exchange server and the restore fails.

    Fixed in 5.5.6 Update 1 Release.

  • The "Restore into RSG/RDB" option is not set to "true" in the Microsoft Exchange server and the restore fails.

    Fixed in 5.5.6 Update 1 Release.

  • MS-Apps backups and restore requests do not complete and the jobs fail to start.

    The Event Manager does not offer useful details about the request failure. Retrying the operation usually results in a successful backup or restore. The cause of this issue is currently unknown.

  • SQL instance warning on Application DB backup wizard should be removed for invalid cases.

    When creating an instance-level backup of a Microsoft SQL server, the Create a new backup wizard displays the following error message:
    The selection of a SQL server instance as a backup target will result in backing up only the database(s) currently present. Future modification to this instance will require modification of the backup job.

    This warning message is not correct. If the user creates an Application database backup without expanding the instance, the backup group automatically picks up the newly-added database and backs it up. Therefore, the above warning is invalid.

  • An unregistered client for a SQL server application database backup displaysthe Sources count incorrectly.

    The application database backup for a Microsoft SQL server displays the client count of zero for an unregistered client backup, even though an MS-App server has been added to the backup job. For the same unregistered client, a full server backup (rather than a database backup) shows the Sources count correctly.

  • SCSI ID Restore: Unexpected error occurs when a disk is restored to the same or alternate powered-on VM

    The error message when a user restores the disk to its original location (and the disk VM is in a powered-ON state) is as follows:
    An unexpected error occurred with the following error code:
    More information may be available in the client logs which can be downloaded from the configuration application (https:// :8543/vdp-configure).

  • The Restore tab does not refresh when connecting to a different VDP Appliance.

    On a vCenter with multiple VDP Appliances, when the user connects to the first VDP Appliance and disconnects (All Actions > Disconnect), and then connects to the second VDP Appliance, the backups from the first VDP Appliance display. If the user browses into one of the backups on the first VDP Appliance, an error displays.

    Fixed in 5.5.6 Update 1 Release.

  • On Microsoft Exchange servers, the Location path field is not validated when the entire backup is selected for restore.

    Validation is not performed on the Location path field (the text box does not turn red when the field is left empty, nor does a tooltip display). When selecting individual databases for restore, however, the validation works as designed.

  • Unable to perform storage expansion unless CPU hotplug is enabled, even if the user decides not to increase the vCPU count.

    When expanding disk storage, the CPU hot plug must be enabled on the virtual machine. CPU and Memory hotplug is enabled by default in version 5.5.5. Previously, users could perform storage expansion even if CPU hotplug was disabled.

  • SCSI ID Restore: Unable to restore a deleted or removed disk to the same VM.

    To reproduce this issue, a backup of a virtual machine with two or more disks is taken. After the backup completes, one of the disks is deleted or removed. From the Restore tab, the deleted disk is selected and the user clicks on Restore. In the Set Restore Options, by default, "Restore to original location" is unchecked. The user selects an empty slot and initiates the restore. The restore operation completes successfully, but in the VM, no new disk is added or restored.

  • The VDP Advanced plug-in switches back to VDP when the ESX host license cannot be determined.

    VDP Advanced switches back to VDP for several reasons:

    • The user deploys a VDP Advanced plug-in on an ESX host with an evaluation license. After the VDP Advanced Appliance is running, the license is changed from an evaluation license to an Essentials Plus license and the Switch to VDPA action generates an error.
    • The user deploys a VDP Advanced plug-in on a corrupt vCenter and the licensing service does not respond.
  • The "Restore into RSG/RDB" option fails when the user specifies the data path rather than the log path.

    Fixed in 5.5.6 Update 1 Release.

    NOTE: The user can leave both the log path and the database path fields blank. If both fields are left blank, the restore defaults to its original location.

  • ABV: A plug-in error is received when the destination host is in the Disconnected state.

    It is expected for the Verification job to fail if the destination host is disconnected; however, the proper error message does not display and the user does not know the root of the failure.

  • Edit backup job wizard: Unable to locate the VM if the VM name has the same name as its resource pool.

    If the virtual machine name has the exact same name as the resource pool in which it resides, the VDP Appliance displays an error message when the user edits the backup job: The following items could not be located and were not selected: <VM-name-here>. Functionally, the backup jobs continue to run properly.

    Fixed in 5.5.6 Update 1 Release.

  • A validated VM when restored under a protected container should not be included in a backup job.

    A temporary virtual machine (that is, a VM with a prefix of VDP_Verifying in the name) should not be included in a backup job. Users should not back up virtual machines created by the Automatic Backup Verification (ABV) feaure. For example, if the user creates a backup job on a host and also selects this host as the destination for an ABV job, the result can be erroneous data that is generated on the server and these VMs will show up as replicated sources.

  • Moving a VM to a resource pool results in a "VM not found" error when editing the backup job.

    The user receives an error message when trying to edit a backup job if a VM was initially in one container, but later moved to a different container. Functionally, the backup job continues to run properly.

    Fixed in 5.5.6 Update 1 Release.

  • ProxyDatastoreUpdater runs every 30 seconds, triggering too many events

    The Proxy datastore updater does not refresh the datastore / proxy relationships unless a new datastore is detected. This reduces the number of events created by this process.

    http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=2067635 references the process to resolve the /space partition filling up because of these events being generated.

  • Loading virtual machine data fails when trying to edit an ABV job.

    To edit an automatic backup verification (ABV) job, the user launches the Create a new backup verification job wizard. On the Virtual Machines page of the wizard (the first page), when the user attempts to load virtual machine data, the "Loading virtual machine data" progress bar spins continuously and the VM data does not display. This issue occurs only on larger configurations (50 - 400+ VMs), where the page stalls but eventually returns.
