Solaris snapctl Driver

The snap driver is invoked by NetBackup under either of the following circumstances

(Solaris systems only):

◆ If the nbu_snap frozen image method is configured for the frozen image source that is

being backed up.

◆ If the client is in a FlashBackup policy and no frozen image method is configured

(Allow frozen image clients on the New/Change Policy display is not checked).

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

Configuration dialog (described in the “NetBackup Configuration” chapter). 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.

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

1 2 ... 166 167 168 169 170 171 172 173 174 175 176 ... 181 182
