Coordinating Snapshot and Backup Operations 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. 2 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 Create Share. 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 Share Properties, then select Create Snapshot Share. 3 Set the backup software to archive the latest version of the snapshot. The SnapServer 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 2008-12-25.120000 2009-01-01.000100 2009-01-07.020100 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, 2009-0107.020100, or January 7th, 2009, 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. A rollback can disable Snap EDR and result in its removal. If this occurs, download the Snap EDR package from the SnapServer web site, reinstall it using the OS Update feature, then reenable and configure it from the SnapExtensions page. 116 SnapServer Administrator Guide
