My advice would be to change your method.
The bparchive command within netbackup will do what you want. It'll backup
a set of files and then delete them if and only if the backup was
successful.
The complication is that it can't be scheduled as a regular job - it has to
be called by a user or cron or similar on the client.
The method would be to generate a list of files to be cleaned from your
server. Feed this list into bparchive using the "-f" option (a file of
files option). If the backup was successful, then they're deleted. Any
error and they remain behind to be attempted again on your next cycle.

Subject: [Veritas-bu] File written to disk during the backup ... does it get
backed up?
I have a backup timing question. If files are written to disk while the
backup is in progress will they be backed up during that backup window? The
reason why I'm asking this is because I have a script that cleans up all the
files once the backup is completed.
This involves database dumps and transaction logs. I just ran into a case
where the DBA said his Oracle extract was still in progress when the backup
was working and the transaction log that was dumped to disk during the
backup may have been deleted by my bpend_notify script. We did not find the
transaction file in the backup nor on the disk so I can only assume that the
script deleted the file. If that's the case is there any easy way to have
my bpend_notify script only delete the files that were backed up?
Thanks in advance ... Mike Day
