Cache for nbu_snap

NetBackup uses the nbu_snap method to create a copy-on-write snapshot in the following circumstances (Solaris systems only):

If the nbu_snap method is configured for the back up on the Snapshot Options dialog.
If NetBackup's auto-selection mechanism chose the nbu_snap method when the backup was initiated.
If the client is in a FlashBackup policy and no snapshot method is configured (Perform snapshot backups on the Policy display is not selected).

In all cases, a raw partition must be specified as cache for the snapshot. Any number of concurrent nbu_snap backups can use the same cache. However, the cache must be large enough to hold copies of all file system blocks that were changed by user activity while the snapshots were active.

In the NetBackup Administration Console, the raw partition cache can be specified in any of three places.
