Volume-level snapshots allow for customizing snapshot schedule and retention rules per individual NAS volume and provide the option for a quiesced snapshot. (Non-quiesced NAS volumes can be imported from cloud snapshots to be used for restore.)
Quiesced volume snapshots freeze file system I/O during the snapshot process. The Quiesce option can be selected when taking a manual volume snapshot and can be enabled within the snapshot profile for automated snapshots.
Snapshots can only be performed on volumes of type=local.
Snapshots can only be performed on volumes of type=local.
Always consider vSAN Usage: When selecting expiration for a snapshot it is important to consider vSAN space utilization. Initially source and snapshot are the same and thus there is no impact on storage utilization; however, as source data diverges more from the snapshot data, there is less deduplication between the two and thus more vSAN usage. It is typically not recommended to use the Never Expire option unless necessary.
To restore a volume from a cloud snapshot, the volume snapshot must first be imported from the cloud snapshot as detailed below. To restore from an individual volume snapshot, skip the import section of instructions and continue to Restore to overwrite -Or- Restore to create new instructions*
From the volume dashboard, click Snapshots on the left menu.
A listing of available snapshots is displayed. Click to select the desired snapshot.
Select Restore over Source from the left menu.
A Warning message will appear to caution that this will overwrite the existing volume and all of its data. By default, Restore Data Only is selected; this option will restore over data within the volume, but not modify any current volume settings. The alternate option: Restore Data and Settings will both restore over volume data and will replace volume settings with those in the snapshot.
Click the Proceed button to continue/ or Cancel to abort.
