Chapter 7 Snapshots A snapshot is a consistent, stable, point-in-time image of a volume that can be backed up independent of activity on the live volume. Snapshots can also satisfy short-term backup situations such as recovering a file deleted in error, or even restoring an entire file system, without resorting to tape. Perhaps more importantly, snapshots can be incorporated as a central component of your backup strategy to ensure that all data in every backup operation is internally consistent and that no data is overlooked or skipped. Note The Snapshot feature described here does not apply to snapshots for iSCSI disks. Supported Windows servers can create native snapshots of iSCSI disks using VSS. For more information, see "Configuring VSS/VDS for iSCSI Disks" on page 93. Topics in Snapshot Management: • Snapshot Management and Usage • Estimating Snapshot Pool Requirements • Adjusting Snapshot Pool Size • Accessing Snapshots • Coordinating Snapshot and Backup Operations Related Information: • Isolate iSCSI Disks from Other Resources for Backup Purposes SnapServer Administrator Guide 111
