Feature Request: move backup validation to include space check

[oxuni_engsci]

Hi, I think it would be very useful if when you invoke 'move backup' the validation process does a check to make sure there's sufficient space.

I was trying to move my backups from a single repository on partiton A to a scale out repository spanning partition A and newly created partition B.

I didn't realise that the move process would first attempt to copy ALL the backup, only cleaning up after everything had moved -- and there wasn't quite enough space on the new partition B (I had assumed that it would move files one VM at a time)

If the validation step did a space calculation beforehand, I think it could avoid some confusion

many thanks!

I guess this is problematic due to block cloning. VBR doesn't know how much space the backup files actually require. It is a long-standing request to let VBR keep this information, since it would be useful for billing etc.
