Coordinating Snapshot and Backup Operations
100 Snap Server Administrator Guide
native ACLs and quotas. Placing this information in a recovery file allows all
backup packages to include this information. If the volume needs to be
restored from tape, or the entire system needs to be recreated from scratch on a
different server, this information may be required to restore all rights and
quota information.
• Offset the snapshot and backup schedules such that the backup does not occur
until you are sure the snapshot has been created. (The snapshot itself does not
require much time, but creating the recovery file may take up to 30 minutes,
depending on the number of files in the volume.) For example, assuming you
schedule nightly backups for a heavily used volume at 3:00 a.m., you might
schedule the snapshot of the volume to run every day at 2:30 a.m., allowing
half an hour for the snapshot to run to completion.

If you have not already done so, create a share for each volume with snapshot
share enabled.
In the Administration Tool, navigate to the
Security > Shares
screen
,
and click
New
. Select the volume you want the share to point to (if you want to create a
share to the root of the volume, simply accept the default path). Click
Advanced
,
then select Create Snapshot Share .

Set the backup software to archive the latest version of the snapshot.
The Snap Server makes it easy to configure your backup software to
automatically archive the most recent snapshot. Simply configure your backup
software to copy the contents of the
latest
directory within the snapshot share
you created at the root of the volume. For example, assume the snapshot share
named SHARE1_SNAP contains the following four directories:
latest
2005-12-25.120000
2006-01-01.000100
2006-01-07.020100
Each directory inside the snapshot share represents a different snapshot. The
directory names reflect the date and time the snapshot was created. However, the
latest
directory always points to the latest snapshot (in this case,
2006-01-
07.020100
, or January 7th, 2006, at 2:01 a.m.). In this case, configuring the
backup software to copy from:
\SHARE1_SNAP\latest
ensures that the most recently created snapshot is always archived.
