Latest Snapshot
Bluearc provides a filesystem view that can be used to access to the "latest snapshot" for a File
System. This view automatically changes as new snapshots are taken, but is not affected by
changes in the live filesystem. The latest snapshot is the most recent snapshot for the File
System, and is accessible through .snapshot/.latest (or ~snapshot/~latest). The latest snapshot
can be exported to NFS clients with the path /.snapshot/latest. Latest snapshots can also be
shared to CIFS clients. When accessing files via the latest snapshot, NFS operations do not use
autoinquiry or autoresponse.
Quick Snapshot Restore
Quick Snapshot Restore is a licensed feature for rolling back one or more files to a previous
version of a snapshot. The procedure is done at the command line, so for instructions, run man
snapshot at the CLI or refer to the "Titan CLI Reference."
Quick Snapshot Restore may report that the file cannot be restored, if it has been moved,
renamed or hard linked since the snapshot was taken. This should rarely occur but, if seen,
indicates that the file cannot be Quick Restored. In this case, the file must be copied from the
Snapshot to the live file system normally, that is, without being Quick Restored.
Snapshot Rules
By setting up a snapshot rule, Titan can be scheduled to take snapshots automatically at fixed
intervals. Setting up a rule is a two-stage process: first the rule itself is defined, and then one or
more schedules are created and assigned to the rule.
To Create Snapshot Rules
1.
From the Home page, click Data Protection. Then, click Snapshot Rules.

Note: The .latest ("~latest") file designation does not show up in directory
listings (i.e. it is a hidden snapshot directory).
