The Site Recovery Manager default configuration enables some simple recovery scenarios. Advanced users can customize Site Recovery Manager to support a broader range of site recovery requirements. Configure Protection for a Virtual Machine or TemplateYou can edit the protection properties of any virtual machine or template in a protection group. You can change the resource mappings, attached storage devices and their datastores, and other properties that control the configuration with which Site Recovery Manager recovers the virtual machine. Configure Resource Mappings for a Virtual MachineIf you have not specified inventory mappings for your site, you must configure resource mappings for individual virtual machines. You can configure resource mappings only if site-wide inventory mappings have not been established. Specify a Nonreplicated Datastore for Swap FilesEvery virtual machine requires a swap file. By default, vCenter Server creates swap files in the same datastore as the other virtual machine files. To prevent Site Recovery Manager from replicating swap files you can configure virtual machines to create them in a nonreplicated datastore. Recovering Virtual Machines Across Multiple Hosts on the Recovery SiteYou can create recovery plans that recover virtual machines across multiple recovery site hosts in a quarantined test network. Resize Virtual Machine Disk Files During Replication Using Replication SeedsvSphere Replication prevents you from resizing the virtual machine disk file during replication. If you used replication seeds for the target disk, you can resize the disk manually. Resize Virtual Machine Disk Files During Replication Without Using Replication SeedsvSphere Replication prevents you from resizing the virtual machine disk file during replication. If you did not use replication seeds during configuration of the target disk, vSphere Replication deletes the target disk when you stop the replication. Reconfigure Site Recovery Manager SettingsUsing the Advanced Settings, you can view or change many custom settings for the Site Recovery Manager service. Advanced Settings provide a way for a user with adequate privileges to change default values that affect the operation of various Site Recovery Manager features.
