Scheduling GFS monthly for tape of copy jobs

Post by pkelly_sts »

[Edit: Case #02081448]

I have 2 sites, each site being largely similar in setup in they they both have a tape library & plenty of B2D capacity so I have what I think is a good strategy to copy each sites backup copy to the local tape library as well so I have Local backup, local copy to tape, copy to remote site, remote site copy to tape, e.g. the backup exists 4 times, 2 sites, 2 different media.

This works reasonably well except for GFS backups as I'd like to also keep a GFS monthly/yearly set on each site as well, this means the tapes on each site can simply stay in the library & auto-rotate & I know I'm still protected from disk/array failure on each site.

However, it seems to me that GFS tape logic really doesn't fit this model and I've never been happy with what I end up with (I've just opened another case related to /last/ months backup ,27-01-17, being written to todays GFS tape, I'm just waiting for the logs to upload before I get the case number which I'll post here as a comment).

I think part of the problem is that I've come in this morning to see a GFS tape job running & processing already, which is I assumed was copying *last nights* overnight copy data, but is actually doing the above job from last month.

Anyhow, what is expected behaviour here if it wasn't doing last months? If I'd copied a job from last night, which completed copying to local storage after midnight last night (so after the GFS job starts waiting) then would you expect /that/ data (e.g. Thursday's backup) to be written to tape?

I really really ONLY wnat Friday data written to GFS tapes, we already know there's no way of stopping GFS jobs starting up a midnight because that's the design (which I don't like much TBH) so it almost sounds like I want/need the schedule to be "The next saturday after the last Friday of the month" if I wanted to guarantee to ONLY capture the results of the Friday job?

The principle of GFS tape jobs is great, they just seem such a major headache in practice & Iv'e been banging my head over it for months now trying to understand the logic (even having read the Veeam documentation countless times for whats *supposed* to happen!).

Is it just me?

You could always disable the schedule for the tape job and trigger the job manually with post-backup script on the job that makes the new full.

I'd forgotten about this post. It actually turned out in my case to be an issue which has since been resolved with support (though i can't remember the specifics now as this was a while ago). I'm not convinced that disabling a GFS tape job is a good idea though, I can't remember the details but I do remember something about a new session being started (or the existing session being closed) whenever you "disable" a tape job so it's something I avoid as much as possible.

To be fair things seem to have settled down a bit in my GFS scenario from this perspective, it's frustrating to troubleshoot due to only happening once-monthly!
