If encryption is enabled, select an encryption strength ( 128-bit or
256-bit ). Using 256-bit encryption (default) provides a stronger
level of security but may have an impact on system performance in
some situations.
Caution: Select 128-bit encryption if you are sending data to a
DXi running a system software version prior to DXi 2.1
Software.
Note: Encryption is enabled by default. However, for best
performance, if your data network is already secured, you
should clear the Use Encryption check box.

The share is recovered on the source system. All data stored on the
share at the time the snapshot was saved is available. The original
export protocol of the share (NFS or CIFS) is retained in the recovery
process.
Note: If you previously remapped your backup application to a
recovered share on the target system, after you failback the
share, you must remap your backup application again to point
to the source system.
Deleting a Snapshot
Delete a snapshot if it is no longer needed. After you delete a snapshot,
it can no longer be used to recover or failback a NAS share.
