Hello, does anyone know how to delete SnapShots with the least amount of extra disk space needed (if the disk got nearly full do to SnapShot's)? I understand, that a SnapShot takes up disk space and in order to delete a SnapShot the data of the SnapShot needs fist to be copied into the virtual disk or another SnapShot and after that the files representing the SnapShot can be deleted to free up disk space. So in general you first need disk space to free disk space. My problem is that the SnapShots for TimeMachine run well for many weeks, but suddenly the bloat up and fill the disk quickly. My question now is: how can this be done in a way that uses the least amount of extra disk space? Consider you have 4 SnapShots and the current state: Snap0 -> snap1 -> snap2 -> snap 3 -> current state In what order do I delete the Snap's to use the least amount of extra disk space? Or asked differently: in what direction will the data of a SnapShot be moved and when will the datafilee from the Snap be deleted? If I delete Snap3 does the data go into the current state or snap2 - and will the datafile for this snap be deleted after completion? Should I delete snap3, snap2, snap1 and last snap0? Or the other way around? I have tried different things but did not understand why sometimes the extra disk space needed is minimal and at other times not. Today I deleted 3 Snap's and the disk was filling up more and more. During deletion I got the msg that no new snap could be generated and around that time the used disk space started to decrease dramatically .. feeing up 100GB of space. So maybe the snap datafilee only get deleted when a new SnapShot is tried to be generated? Any insight is wellcome.
