Symantec's Veritas NetBackup is a backup and recovery tool that can be integrated into RMAN (Oracle's libobk library) to backup the Oracle database. NetBackup support both off-line and online database backups.
 Oracle agents
Netbackup has two agents that can backup Oracle databases, they are:
- Netbackup for Oracle; and
- Netbackup for Oracle Advanced BLI (Block level Incremental)
The first is part of standard NetBackup while the BLI agent is part of the (extra cost) NetBackup Snapshot Client option. The BLI agent reduces the amount of data that needs to be backed-up by only backing-up changed data blocks. The result is reduced CPU utilization and network use. These changed data blocks are tracked by the VERITAS Database Edition for Oracle storage checkpoint.
 RMAN Integration
When allocating channels, specify the SBT library. Example:
allocate channel t1 type 'SBT_TAPE' parms 'ENV=(NB_ORA_CLIENT=my_host_name),SBT_LIBRARY=/usr/openv/netbackup/bin/libobk.so64.1'; allocate channel t2 type 'SBT_TAPE' parms 'ENV=(NB_ORA_CLIENT=my_host_name),SBT_LIBRARY=/usr/openv/netbackup/bin/libobk.so64.1';
 Changing parameters
NetBackup would normally allow you to override parameters from the "allocate" command (see above) or by using RMAN's "send" comamnd. Example:
RMAN> send 'NB_ORA_CLIENT=name'
 Checking NetBackup log files
To check the NetBackup log files, see tape mounts, etc:
$ cd /usr/openv/netbackup/logs/user_ops/dbext/logs $ ls -ltr $ tail ...
