You can run a quiesce compatibility check to determine if VMs are compatible with quiesced snapshots.

Requirements for quiesced snapshots:
  • VMs are powered on.
  • VMware Tools installed and running. VMware Tools requires VSS (Volume Shadow Copy Service) or you cannnot take quiesced snapshots.
  • Linux VMs only: Pre-freeze and post-thaw scripts installed on the VMs. For information, see Enabling Linux VMs for Quiescing. The quiesce compatibility check does not check for these scripts on Linux VMs.
Note: VMs with high-frequency snapshots cannot be quiesced.


  1. From the left navigation, select Protection groups.
  2. From the upper-right side of the Protection groups page, click Create protection group. Or, select an existing protection group and click the Edit group button.
  3. In the General page, enter a name for the protection group.
  4. Next, select a protected site and a vCenter. The dialog box also displays the cloud file system associated with the protected site, which is where snapshots replicate to.
  5. After you select a protected site and vCenter, the system checks the vCenter for software compatibility with high-frequency snapshots. If the protected site is compatible, the High-frequency option is selected. Deselect the High-frequency option.
  6. Next, select the Quiesce option.
  7. To check if the VMs on the protected site have VMware Tools installed to enabled quiesced snapshots, create any type of query (name pattern, tags, folders).
  8. Click Quiesce compatibility check.
    When the check finishes, there are three possible states for each VM:
    • Question mark icon. VMware Tools is not running. Quiescing not supported.
    • Warning icon. VMware Tools is out of date. Quiescing might fail.
    • Green light icon. VMware Tools is installed and running. Quiescing supported.
    Note: The quiesce compatibility check does not check if a VM has a high-frequency snapshot associated with it. If a VM already has a high-frequency snapshot taken, then that VM cannot be quiesced, even if it has VMware Tools installed. The quiesce compatibility check also does not check if Linux VMs have pre-freeze and post-thaw scripts installed, which is required for quiescing Linux VMs.
  9. If the check passes, you can proceed in creating the protection group.
