Making a Backup of an Online Database on the Same Host
As illustrated in “Example System Configuration for Database Backup on the Primary Host” on
page 28, the primary database volumes to be backed up, dbase_vol and dbase_logs, are
configured on disks attached to controllers c1 and c2, and the snapshots are created on disks
attached to controllers c3 and c4.
Example System Configuration for Database Backup on the Primary Host
Note It is assumed that you have already prepared the volumes containing the file systems for the
datafiles to be backed up as described in “Setting up Volumes for Instant Snapshots” on
page 17. For an Oracle database, it is not necessary to create snapshots of the volumes
containing the file systems for the redo log volumes or archived logs.
