Accessing Snapshots Within the Snapshot Share
A snapshot share contains a series of directories. Each directory inside the snapshot
share represents a different snapshot. The directory names reflect the date and time
the snapshot was created. For example, assume the snapshot share named
Sales_SNAP contains the following four directories:
latest
2008-12-25.120000
2009-01-01.000100
2009-01-07.020100
The latest directory always points to the most recent snapshot (in this case, 2009-
01-07.020100, or January 7th, 2009, at 2:01 a.m.). A user may view an individual
file as it existed at a previous point in time or even roll back to a previous version of
the file by creating a file copy to the current live volume.
The latest subdirectory is very useful for setting up backup jobs as the name

of the directory is always the same and always points to the latest available
snapshot.

Coordinating Snapshot and Backup Operations

Like backups, snapshots can be scheduled to recur at a designated time and
interval. In addition to synchronizing the backup and snapshot schedules, you must
create a share (and snapshot share) to the appropriate directory so that the backup
software can access the snapshot. For most backup purposes, the directory specified
should be one that points to the root of the volume so that all of the volume's data is
backed up and available from the snapshot share.
Create a snapshot for each volume you want to back up.

• Put a check in the

snapshot. This step is needed because many backup packages do not back up
native ACLs and quotas. Placing this information in a recovery file allows all
