Backing Up Your Data with Snapshots Backing Up Your Data with Snapshots Note To create snapshots on systems running Windows XP, Windows Vista, Linux, or VMware, you must use the CLI (see page 177.) Snapshots created on these OSs are fail-consistent only, as the VSS Provider is not supported by the OSs. Adaptec Storage Manager's snapshot feature creates a frozen copy of a volume at a point in time. A snapshot sets up a link between the source volume and the underlying logical devices in your iSCSI Storage Appliance. When data on the source volume changes, the differences are captured on the snapshot drive. If an error occurs on the volume, you can roll back the volume to the point in time when the snapshot was created. You can also use the snapshot feature for tape backup, drive cloning, and multi-server rollout. Adaptec Storage Manager has a snapshot wizard to help you create a snapshot and snapshot sets (a group of snapshots taken at the same time). A snapshot can include one volume or multiple volumes, including mirrored volumes. You can't work with any individual snapshot in a snapshot set; only the complete snapshot set can be mounted or deleted, for example. You can choose to run a snapshot job immediately, or schedule it for another time. Before You Begin Ensure that the VSS Provider (see page 17) is installed on the system on which you plan to take snapshots. Also ensure that Microsoft Hotfix 913648 or equivalent is installed on the system. Refer to http://support.microsoft.com/kb/895092. Creating a Snapshot from an iSCSI Storage Host Volume You can create a up to 256 separate snapshots on one iSCSI Storage Appliance. (You can include multiple volumes in one snapshot.) You cannot create a snapshot of either a mirrored volume (the mirror manager) nor its mirror (the mirror plex). You can also schedule snapshots to be created on a recurring basis. For more information, see To create a snapshot: 1 In the Enterprise View, select the iSCSI Storage Host you want. 2 In the Volumes View, select a volume or mirrored volume. 3 Click the Snapshots button (shown at right). Or, In the Actions menu, select Create snapshot. The wizard opens. 64 Snap Server 700i Series User's Guide
