GFS Tape question

[pkelly_sts]

If I have a GFS tape job configured to run monthly on the last Friday of the month then by default it starts at 00:00 on the scheduled day.

However, the info at https://helpcenter.veeam.com/backup/vsp ... e_hiw.html says:

"At 00:00 of the day set in the GFS job schedule the GFS job starts and checks periodically if the source job created a backup:"

Does this mean that as of 00:00 it starts watching for new runs of jobs, and if it sees one, it'll then either copy it (if was a full) or synthetically generate a new full (if was incremental)?

In other words, as of 00:00, it isn't going to look at any jobs that already ran the previous night & copy those RPs, UNLESS the source job doesn't run by 00:00 the next day, at which point the GFS job will then synthetically create a new tape-full based on the most recent RP found?

If one of the source jobs is a backup copy job (without any associated GFS retention) which doesn't complete its copy until, e.g. 05:30, then will it pick up that RP rather than wait for the RP that runs/copies that night?

Correct. If no new restore points will be created within a day, a GFS backup to tape job will leverage the latest available one.

Also, there is a regkey controlling the said behaviour. Using it, you can set a timeout after which GFS job will check previous days to find suitable GFS candidate. Default value is 24 hours.

Thanks.

OK cool, thanks for the clarification, 24hrs should suit me fine.

I will reference it here just in case you need it in future. Thanks.
