Hello there.
I have a setup with vchanger serving 4 physical disks. On those disks I
have fixed-size media files.
It works as it should but it doesn't fulfill all my needs.
It does rotate between disks when a particular physical disk gets full (all
medias on that drive are used) but it might do so - for example - mid-job.
Back when I had shorter retention it didn't care that it didn't rotate
between disks for a longer time.
So ideally I'd love to have a situation when I'd have a full job and
subsequent diff/inc jobs created on one disk, then rotate to another
physical disk (the old one I unplug and store off-line) and do
full+diff/inc there and so on. For example in a weekly schedule.
But so far the only Idea I have would be to create a separate pool on each
physical disk and have multiple intertwined jobs - each with a week-long
schedule and multiple-week "pause". Each job would target a different pool.
The downside is of course the administrative overhead to create and
maintain all those jobs and having to reconfigure it as a whole in case I
add or remove disks to/from the rotation pool.
I just browsed the docs in parallel windows and I see that I can override
job-level settings with schedule so maybe it's the way to go. Create
separate pools per physical disk and do something like:
Schedule {
Name = "TriDisk"
Run = Pool=FirstDisk Full w01/w03 sat at 21:00
Run = Pool=SecondDisk Full w02/w03 sat at 21:00
Run = Pool=ThirdDisk Full w03/w03 sat at 21:00
Run = Pool=FirstDisk Incremental Full w01/w03 mon-fri at 21:00
Run = Pool=SecondDisk Incremental Full w02/w03 mon-fri at 21:00
Run = Pool=ThirdDisk Incremental Full w03/w03 mon-fri at 21:00
}
Still a bit troublesome to maintain but better than defining separate jobs.
Any better ideas?
