To restart jobs in NetBackup from the command line, you can use the bpdbjobs command.
For example, if job 12345 failed, you can re-run it using the following command:
/usr/openv/netbackup/bin/admincmd/bpdbjobs -restart 12345
If you want to restart multiple jobs, you just need to separate the job IDs with a ,.
Ex.
/usr/openv/netbackup/bin/admincmd/bpdbjobs -restart 12345,12346
