Restoring snapshots

Restoring data from a snapshot involves a simple copy operation from the snapshot directory to the target/secondary system. The restore operation overwrites the existing volume configuration. Any changes that are made to the data in the volume after the Snapshot copy is created, are lost.

To restore snapshots refer, Creating restore jobs.

Setting expiry for Snapshots

Each snapshot has an expiration date and time, you can preserve a snapshot to prevent it from expiring. Snapshot expires when the backup Saveset expires, even if the snapshot expiry date is greater than Saveset Expiry date. However, if this snapshot is already mounted, the snapshot goes in the pending state if the saveset has expired.

To set an expiry date of snapshot
1
In the navigation pane, click Create Restore Job.
2
On the Create Restore Job — Choose Saveset page, select the SaveSet Name and then click Explore Snapshots.
3
Select the snapshot from the Saveset Name list and click Set Expiry.
4
Select Change Expiry Date, and choose the options to set the expiry date and click Ok.

On: Set the date from the calendar and set the time
b
Now: Snapshot expires Immediately.
c

NOTE: In case of Huawei OceanStor Device Manager, you can only set an option to expire snapshot immediately.
In the Explore Snapshot page, the Expires column updates the date and time.

Mounting Snapshots

You can mount any available snapshot, to access the data available in the snapshot. Snapshots must be mounted on a MediaAgent with the same operating system as the snapshot volumes. Currently, snapshots are mounted only on Windows machine. You can mount these snapshots on a particular drive or a specified empty folder. Once the snapshot is mounted you can view the details of each snapshot, which helps during the restore operation.

NOTE: In case of Huawei OceanStor Device Manager, to mount a snapshot, the host where the LUN is mounted and host where the snapshot will be mounted must be in same host group.
