There are ~500MB difference between the current status and the previous snapshot. So deleting that snapshot and pruning would give you 500MB back I guess. Bad thing is that when you have a lot of snapshots with the same files modified, this is near impossible to calculate manually, but there must be a way of calculating this :-) Cheers, Antonio 2009/8/27 Thomas Nikolajsen <[email protected]>: >>>Presently there is no tool to see space used for a given snapshot, or PFS, >>>this could be a nice feature. >> >>I usually do >> >>du -hs <fs>/snapshots/snap*/ > > The info I would like to see is space which can be recovered by deleting > snapshot. > (i.e. doing prune & reblock after deletion) > > The command you suggest might give an approximation for that. > > Guess I wasn't precise enough in my wording ;-) > > -thomas > >
