8.1.3 Volume Snapshot
Snapshots are point-in-time copies of a logical volume. This allows the system administrator to create
a new block device which presents an exact copy of a logical volume, frozen at some point in time. As
changes are made to the original volume, the snapshot remains the same and looks exactly like the
original at the time the snapshot was created.
A Snapshot can be created manually or scheduled. Admin needs to enable first this special function.
NOTE: Logical Volume with snapshot cannot be extended nor replicated (see
next section about Volume Replication).
To enable Snapshot function, select Volume Manager then click Options tab. Click the “Enable
Snapshot function” option.
NOTE: Creating Snapshots while a Logical Volume is under heavy I/O will
slowdown the I/O access or interrupt the I/O process to a Logical Volume. This
means that clients accessing the proNAS share, in which the Logical Volume is
under snapshot, can experience slow write access.
