1.3.3 Backing Up the Cluster

It is important to back up your cluster on a regular basis. Even though Sun Cluster provides an HA environment, with mirrored copies of data on the storage devices, do not consider this to be a replacement for regular backups. Sun Cluster can survive multiple failures, but it 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 as your volume manager
