Off-host cluster file system
backup
Veritas Cluster File System (CFS) allows cluster nodes to share access to the
same file system. CFS is especially useful for sharing read-intensive data
between cluster nodes.
Off-host backup of cluster file systems may be implemented by taking a
snapshot of the volume containing the file system and performing the backup
operation on a separate host.
Figure 4-1 shows an example where the primary volume that contains the file
system to be backed up is configured on disks attached to controllers c1 and c2,
and the snapshots are to be created on disks attached to controllers c3 and c4.
See “Mounting a file system for shared access” on page 43 for a description of
how to mount a VxFS file system for shared access by the nodes of a cluster.
See “Using off-host processing to back up cluster file systems” on page 43 for a
description of how to perform off-host backups of cluster-shared file systems.
