How this works for affordable disaster recovery
If the storage systems in your primary location fail or volumes become unavailable, the off-site
location contains the most recent remote snapshots.
• Use the remote snapshots to resume operations as shown in Figure 13 (page 39). If you created
tape backups, you can recover data from tape backups, as shown in Figure 14 (page 39).
• Only data written to the primary volumes since the last remote snapshot was created will be
unavailable.
• Application servers that were accessing the offline volumes will not be available until you
reconfigure them to access recovered data.
To resume operations using the most recent set of remote snapshots:
1. In the backup location, make the remote volume into a primary volume.
