You can configure a separate snapshot schedule for each volume and LUN.

This setting is only available when taking a snapshot of a block-based LUN.

---|---|
Crash consistent |
The snapshot records the state of the data on the LUN. |
Application consistent |
The snapshot records the state of data and applications on the LUN. The iSCSI host flushes data in memory to the LUN before QTS takes a snapshot. If VMware vCenter is using the LUN, vCenter takes a virtual machine snapshot. Important:
This option is only available for VMware vCenter, or for Volume Shadow Copy Service (VSS) aware applications running on a Windows server. You must install QNAP Snapshot Agent on the iSCSI initiator. |
When enabled, QTS only takes a snapshot if data on the volume or LUN was modified since the last snapshot was taken.
The description helps you to identify the snapshot.
A confirmation message appears.
QTS starts taking snapshots according to the schedule.
