Everyone who has worked with ADV_FILE devices knows this situation: a disk backup unit fills, and the saveset(s) being written hang until you clear up space, because as we know savesets in progress can’t be moved from one device to another:

Honestly, what makes me really angry (I’m talking Marvin the Martian really angry here) is that if a tape device fills and another tape of the same pool is currently mounted, NetWorker will continue to write the saveset on the next available device:

What’s more, if it fills and there’s a drive that currently does have a tape mounted, NetWorker will mount a new tape in that drive and continue the backup in preference to dismounting the full tape and reloading a volume in the current drive.

There’s an expression for the behavioural discrepancy here: That sucks.

If anyone wonders why I say VTLs shouldn’t need to exist, but I still go and recommend them and use them, that’s your number one reason.
