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.
