About Snapshots
Snapshots enable you to capture volume data at a specic point in time without disrupting access to the volume.
A snapshot represents the contents of a volume at the time of creation. If needed, a volume can be restored from a snapshot.
Creating a snapshot does not prevent access to a volume, and the snapshot is instantly available to authorized iSCSI initiators. Similar to
volumes, snapshots appear on the network as iSCSI targets, and can be set online and accessed by hosts with iSCSI initiators.
You can create a snapshot of a volume at the current time, or you can set up schedules to automatically create snapshots on a regular
basis.
If you accidentally delete data, you can set a snapshot online and retrieve the data. If a volume is corrupted, you can restore the volume
from a snapshot.
NOTE: Generally, snapshots will not be deleted unless you take action to delete them. In some instances, however, snapshots can
be deleted by the system. For example, when a new snapshot is taken and not enough snapshot reserve space is available for the
new snapshot and the previous one, the older one will be deleted. A snapshot can also be deleted during snapshot borrowing if
you run out of borrowable space.
Create a Snapshot
You can create a snapshot of a single volume at the current time. Snapshot creation occurs immediately, with no impact on volume
availability or performance.
