Snapshots

In a logical sense, snapshots capture an instant state of data of the target volume. The
underlying logic is Copy-on-Write—copying the data that is being written at the time of the
data capture.
Snapshots are stored in a reserved space set up within the RAID Group (similar to a virtual
disk). Each RAID Group on the system contains only one such Snapshot Pool. This pool
contains all snapshot data for all virtual disk volumes on the RAID Group.
