Creating a snapshot collection
You can create snapshots of all the volumes in a volume collection in one operation. The resulting set of snapshots,
one for each volume in the collection, is called a snapshot collection.
Requirement: Be
fore you create a snapshot collection, you must allocate snapshot reserve for each volume in the
volume collection. See About snapshot reserve settings on page 1
1-2.
1. Click
Volumes, then expand Volume Collections, then select the collection name, and then click Create
snapshot now.
2. In the Create Snapshot Collection dialog box, enter an optional description (up to 127 ASCII characters).
3. Click
OK.
Snapshot collections appear under the volume collecti
on name in the far-left panel.
The default snapshot collection name is th
e volume collection name, followed by the date and time when you
created the snapshots (for example,
datavols-2009-03-25-15:31:14.7668). However, when snapshot
collections appear under a volume collection, you can identify them only by timestamp.
Displaying snapshot collections
1. Click Volumes, then expand Volume Collections, then select the collection, and then click the
Snapshots tab.
The Snapshot Summary panel shows the number of snapshot collec
tions for the volume collection, the most
recent snapshot collection timestamp, and any snapshot schedules for the volume collection.
2. Expand a snapshot collection in the Snapsh
ots panel to display the individual snapshots that comprise the
collection. A snapshot that is part of a snapshot collection also appears under its volume name in the far-left
panel.
3. Place the pointer over the snapshot collection
or a snapshot to display details.
Displaying snapshot collection details
1. Click Volumes, then expand Volume Collections, then expand the collection.
2. Select the snapshot collection timestamp. The Volume Collection – Snapshot Collection
window appears.
The Snapshot Collection Status panel describes
the snapshot collection, including the volume collection name, the
time you (or a schedule) created the snapshot collection, the original number of snapshots in the collection, and the
collection Integrity status and Modification status.
The snapshot collection Integrity status can be:
•
complete — A snapshot exists for each volume in the collection.
•
incomplete — A snapshot that was originally part of the collection does not exist.
