Veritas Cluster Integration

1. Install the Data Protector Disk Agent on each system with the local
disk you want to back up.
2. Configure a backup of the local system in the cluster and define the
local disks you want to back up.
Backing Up Shared Disks
A shared disk can only be backed up as a local disk, as described above.
It can however be backed up from any of the cluster nodes between which
it is shared.
For example, to back up a disk shared between two nodes:
1. Install the Data Protector Disk Agent on each system that shares the
disk.
2. Define a backup specification for the disk as a “local disk” on each
system.
3. If you want to safeguard the backup of the shared disk further, you
could create a post-exec within each backup specification that checks
for errors and starts a backup on the other system, if the first fails.
