Managing Snapshots

Explore snapshots is a feature that allows you to view, mount, and unmount the existing snapshots.

Explore snapshot feature is currently supported for Dell Storage Manager, Huawei OceanStor Manager, and NetApp ONTAP Device Manager. To add these storage manager’s refer Managing the Snapshot Array Manager. Currently, NetVault Plug-in for FileSystem supports snapshot-based backups.

You can perform following operations:

•
Restoring snapshots
•
Setting expiry for Snapshots
•
Mounting Snapshots
•
Unmounting Snapshots
 
* 
NOTE: If you create snapshots in version 12.0 and upgrade NetVault server to 12.1, the snapshot mount and unmount operation does not support. In this case you need to upgrade NetVault client to 12.1.

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.
•
Now: Snapshot expires Immediately.
•
Expire with Saveset: Snapshot never expires.
* 
NOTE: In case of Huawei OceanStor Device Manager and NetApp ONTAP 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 the 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.
NOTE: In the case of NetApp ONTAP Device Manager, to mount a snapshot, the host on which the LUN is mounted and the host where the snapshot will be mounted must be in the same initiator group.
To mount a 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 to mount and click Mount.
4
Select the machine to mount the selected snapshot, and click Next.
You can mount the snapshot on multiple client machines.
5
Select the drive or folder path to mount the snapshot.
To mount the snapshot on drive:
•
Select Mount using drive letter, and select the drive from the list, and click Mount.
 
* 
NOTE: The drive letter of the respective client machine is not available which is already used by the client machine.
To mount the snapshot in a folder:
•
Select Mount in folder, and browse the folder for the mount point, and click Mount.
You can select empty folder from any of the drives available for the selected machine.
•
In the Explore Snapshot page, the status in Mounted column changes to Yes.
