Solaris snapctl Driver

Under normal conditions, the snap driver is invoked only by NetBackup. The snap driver

is invoked if the nbu_snap frozen image method is configured for the frozen image source

that is being backed up.

A cache partition must be specified for the cache parameter in the Frozen Image Client

Configuration dialog (described in Chapter 4, “NetBackup Configuration”). The same

cache can be used by any number of concurrent nbu_snap backups, as long as it is big

enough.

The cache size should be approximately 10% to 15% of the total of all frozen image sources

that are associated with the specific cache. This assumes no more than a moderate level of

write activity during backups.

If a cache overflows, all snapshots that are using the cache will become unreadable and

the backups that are reading the snapshots will fail.

Command Usage

snapoff

snapoff terminates a snapshot that was previously initiated by a backup that failed

abnormally. snapoff must be invoked as:

/usr/openv/netbackup/bin/driver/snapoff snap1 ... snapn
