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.

As illustrated in System Configuration for Off-Host File System Backup Scenarios, 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 created on disks attached to controllers c3 and c4.

See Mounting a File System for Shared Access 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 for a description of how to perform off-host backups of cluster-shared file systems.
