Description

Take a new snapshot before reverting

This ensures that changes made to data since the

Enable encryption during transfer

QTS encrypts the snapshot before sending it for

additional security.

Reverting a LUN Using a Remote Snapshot

Reverting restores a shared folder or LUN to the state at which the snapshot was taken. Restoring data

using snapshot revert is faster than restoring individual files and folders.

Warning

• While reverting, ensure that data in not being accessed on the LUN. The safest way to

do this is to disconnect all iSCSI initiators. Accessing the LUN during a snapshot revert

might result in data loss.

• Restoration time depends on the amount of data being restored and the connection

speed between the two NAS devices.
