Configuration for off-site backup and recovery

To use remote snapshots for off-site tape backup, create remote snapshots for access by your tape

backup application:

• Create remote volumes in your backup location.

• Configure your backup application to access the remote snapshots.

• Configure schedules to create remote snapshots in the designated off-site locations. If your

application server uses multiple volumes that must be in sync, use a script to quiesce the

application before creating remote snapshots.

• [Optional] Create routine tape backups of the remote snapshots.

How this configuration works for off-site backup

Depending on how long you retain the copies of the remote snapshots, you can retrieve data

directly from recent remote snapshots rather than using tape backups. Otherwise, retrieve data as

you normally would from the tape backup.

Best practices

Retain the most recent primary snapshots in the primary cluster

By keeping snapshots on your primary volume, you can quickly roll back a volume to a previous

snapshot without accessing off-site backups.

• When you create a schedule for Remote Copy, specify the number of primary and remote

snapshots that you want to retain. You can retain primary snapshots to facilitate easy rollback

of the primary volume.
