Restoring Data; Restoring A Nas Volume From A Snapshot; Deleting A Snapshot - Dell PowerVault NX3500 Administrator's Manual

Snapshots retain the same security style as the Active file system. Therefore,
even using Snapshots, users can access only their own files based on existing
permissions. The data available when accessing a specific Snapshot is at the
level of the specific share and its subdirectories, ensuring that users cannot
access other parts of the file system.

Restoring Data

You can restore data in two ways:
• Copying and pasting: Individual file restores
If you have accidentally deleted or modified a file and would like to restore
it, access the snapshot directory located in the current NFS Export or
Share, find the requested snapshot (according to its time of creation) and
copy the file to its original location. This method is useful for the day-to-
day restore activities of individual files.

Restoring a NAS Volume from a Snapshot

If you need to restore an entire volume (in case of application error or virus
attacks), where copy and paste of huge amounts of data takes a lot of time,
the entire NAS Volume can be restored.
Restoring a NAS Volume From a Snapshot
1 From the NAS Manager, navigate to Data ProtectionSnapshots
Restore.
2 Choose the NAS volume to be reverted and a snapshot revision name to
revert to.
All data written to the volume after the reverted snapshot was taken is
deleted. A snapshot taken of the volume after the reverted snapshot is
deleted as well.

Deleting a Snapshot
