If I understand you correctly, you might be able to set the VM back job, that finishes last, to run a post script. The post script would run the copy files to tape command. This command is provided by Veeam B&R when you setup any backup job in the summary view.
I use post commands to initiate backup to tape via backup exec immediately after the last job finishes. Avoiding playing with schedules. Unfortunately Bexec didn't give you the command to just copy/paste in veeam :)

the other annoyance is I can't schedule a "copy files to tape" job to run after a regular backup job, that would be OK for the interim.

As mentioned, the post-job activity of a normal backup job would be the best option, indeed. There you can specify either the command that is shown in the backup job summary or the PS one-liner responsible for job execution. Thanks.

Not sure my request is identical, but similar, so using this thread. My full backup of active data is 500 GB total and I have a large repository for the backup, and LTO 5 tape for secondary target. I was experimenting with synthetic fulls, and they are pretty quick (2 hrs), so I set it on syn full every day (yeah, overkill) and then dup to tape. What I expected was one syn full on every tape, but... the dup to tape job asks for multiple tapes and goes to multiple TB, so apparently not.

My main question is.... When I ask to copy a VBR7 backup job (not file) to tape, what exactly gets copied? Every VBR backup ever for that job that is within retention range? Everything back to the last true full? Just the latest and greatest? It would be nice if I could pick any of those, but for now, what is it trying to do?

My secondary question is that the software indicates reverse incremental will not work for copies to tape but you seem to be saying the opposite here? I must be missing something basic.

Backup to tape job copies every .vbk and .vib files that can be found in a given “source”: be it backup job or backup repository.

My secondary question is that the software indicates reverse incremental will not work for copies to tape but you seem to be saying the opposite here

Backup to tape job will work in case of reversed incremental mode, though, .vrb files will be skipped from processing. Also, be aware that with reversed incremental mode, each day there will a whole full backup copied to tape medias; thus, it’s recommended to utilize incremental mode, instead.

Thanks.

Um, that is stunning logic of copying everything ever done to tape. IMO, choices should be type (full;syn full;incr;rvse) and date range (last xx days), so this is an enhancement request.

If I select reverse incremental for the backup job with secondary to tape, "a whole backup to tape" means what? - the most recent vbk to tape with no other files?

Correct.

And thank you for the feedback. We are going to considerably improve tape functionality in future releases.

Checking directories and job and job history, I see
1) Repository has 7.5 TB in the directory for this job (mix of file types, vbk and vib)
2) Job on 17th (syn full) processed 787 GB and created a 510 GB vbk file. Tape step pushed 2.5TB to tape. Day before was 1.5TB to tape (same job GB).
3) Looking back over the past couple weeks, I see no pattern, pushing 510GB to tape, but occasionally 1.5TB or more. Occasionally.

Sorry to beat this to death, but just trying to get a grip on logic. Tapes have only saved me from total data loss twice in 25 years, but those were 2 good saves. I have used cloud backups from others and the seeding process was excruciating plus I know a company that did not renew their offsite storage once upon a time. I already own a pretty decent tape drive, so thought I would use it.

I want the latest vbk full+inc (or syn full) on tape. I guess I need to figure out powershell until VBR is updated?

As mentioned in the adjacent thread, it’s not possible with the current implementation to push only latest .vbk to tape, using “backup to tape” job. So, for now you can, probably, put into use the script that utilizes file to tape job in conjunction with hard links.

Anyway, thanks for the feedback; much appreciated. We will consider how existing functionality can be improved in the future product releases. Thanks.

I set up the script and that was much easier than expected, and worked just fine. Changed delete to *.vbk instead of *.* just because that makes me less nervous.

Additional precaution won’t be harmful, indeed. :)
