I write to disk, then use the bpduplicate command to create a tape copy.
After a verification that I have a good tape copy, I immediately expire the
disk image with "bpexpdate -d 0 -backupid <id> -force". The on-disk copy is
immediately removed.
I'm doing this with a scripted process (not vault) under v3.4 but there's no
reason it shouldn't work with v4.5

Subject: [Veritas-bu] Disk based backups with Netbackup 4.5fp3
Hi,
I am currently investigating the theory of backing up images to disk and
then Vaulting them to tape once the backup has been completed using
Netbackup Vault.
The process that I have been following in my test plan is as follows
1) Manually initiate a backup to disk.
2) Manually initiate the vaulting profile which duplicates the disk image to
tape and then forces expires the disk image in 1 hour.
The first problem that I had was that after the hour the disk image reflects
that it should have expired, but the disk image was still present. This
could be see by the bpimagelist command for the client and a ctime command
against the EXPIRATION field in the client.f file.
I have queried this with Veritas and the answer there is that this would be
a standard process as the image will only clear when a nights schedule
ends, or I can implement a work around solution of a manual process of
creating the CLEAN_IN_BACKGROUND file and running the bpimage -cleanup
-allclients command to delete the expired images.(TECHNOTE - 236274)
I have tested the scheduling process as specified by Veritas by scheduling
everything but it seems that even though the image is set to expire, the
actual disk image will only clear once the scheduled backups have been run,
which in this case would be the next nights backup schedule.
With the limited resources that I have I can not afford to hold two nights
images on disk.
If there is anyone else who is following the same process, please can you
advise me on the process that you follow to backup the images to disk, vault
them to tape and then clear them in the shortest time possible.
Thank you in advance.
Andrew Walker
