Achieving affordable disaster recovery

Even if you do not have clustered application servers or network bandwidth required for configuring

hot backup sites, you can still use Remote Copy to protect your data during an emergency.

Using remote snapshots, you can maintain copies of your volumes in remote sites. Set up a schedule

for creating remote snapshots, and if your primary storage site becomes unavailable, you can

easily access the most recent remote copy of your data volumes. You can also use remote snapshots

to transfer data to a backup location where tape backups are then created. This eliminates the

backup window on your primary volumes, and ensures that you have copies of your data in the

remote site on storage systems as well as on tape.

To configure affordable disaster recovery, create remote snapshots of your volumes in an off-site

location. In addition, you can create tape backups from the remote snapshots in the off-site location:

Designate one or more off-site locations to be the destination for remote snapshots.

Set up a schedule for creating 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.

Create routine tape backups of the remote snapshots in the off-site locations.
