Snapshots
A snapshot is a point-in-time, read-only copy of an iSCSI virtual disk.
Creating snapshots of iSCSI virtual disks facilitates backup and recovery
operations. Snapshots are used as interim copies of data that have been
modified since the most recent backup. Snapshots offer the following
advantages:
•
Snapshots can be scheduled to be created automatically.
•
Snapshots are space-efficient because they are differential copies.
•
It is not necessary to close files or stop programs when creating
snapshots, so application servers can continue servicing clients without
disruption.
•
Each snapshot is typically created in less than one minute regardless of
the amount of data.
•
Snapshots are useful for fast system recovery of files and volumes, in
case of accidental data deletion by a user, overwritten data, or data
corruption resulting from a malicious program.
•
Snapshots can be mounted locally or exported to facilitate backup and
recovery operations.
