Data Backup Options
Snap Appliance provides four native applications—Snapshots, Backup Express for
GuardianOS, Server-to-Server Synchronization, and DataKeeper —that you can use
to enhance your backup procedures. Backup Express for GuardianOS provides
native tape backup support, Snapshots ensure that the file system you back up is
internally consistent and complete, and S2S provides an alternative way to back up
data to disk. If you wish, you can also use backup products from Computer
Associates, Legato, and Veritas with your Snap Server.
Using Snapshots to Optimize Data Backup
Snapshots can satisfy minor, short-term backup situations such as recovering a file
deleted in error, or even restoring an entire file system, without resorting to tape.
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.
• On-demand file recovery —
A Snapshot share (see page 100) provides users with
direct access to archived versions of their files. Users who wish to view or recover
an earlier version of a file can retrieve it on-demand without administrator
intervention.
