Backing Up the Cluster

Back up your cluster on a regular basis. Even though Sun Cluster software provides a highly available environment, with mirrored copies of data on the storage devices, Sun Cluster software is not a replacement for regular backups. A Sun Cluster configuration can survive multiple failures, but does not protect against user or program error, or catastrophic failure. Therefore, you must have a backup procedure in place to protect against data loss.

The following information should be included as part of your backup.

• All file system partitions

• All database data if you are running DBMS data services

• Disk partition information for all cluster disks

• The md.tab file if you are using Solstice DiskSuite Solaris Volume Manager as your volume manager
