Dell PowerStore Protecting Your Data

Restore a storage resource from a snapshot

The restore operation is used to reconstruct an environment following an event that may have compromised its data. You can use the restore operation to replace the contents of a parent storage resource with data from a direct child snapshot. Restoring resets the data in the parent storage resource to the point in time at which the snapshot was taken.

Before restoring a snapshot, it is mandatory to shut down the application and unmount the file system that is running on the production host, and then flush the host cache to prevent data corruption during the restore operation.

If you restore a volume group, all member volumes are restored to the point in time associated with the source snapshot.

When restoring a resource from a snapshot that was replicated from a remote system, check the source data time value to ensure that you are using the correct snapshot.
