To me it sounds pretty obvious;
“…but it happens every 3 schedules“
Lets say you have 1 vm @ 300GB, and your backup store is 800GB in total. The first two will backup – no problem. 3rd will fail due to lack of space, yet still remove the oldest – bringing the store usage back down to 300-ish GB. 4th will then work, and remove the 2nd. 5th will then work and remove the 3rd (faulty) one. 6th will then fail again because of lack of space - the store can’t handle 3 simultaneous backups.
And I’m not even certain that a 3 rotation backup will hold only 3 copies. AFAIK ghetto will only remove the latest backup after a fresh one completes. I.e. you would need space for a total of 4 times the vm your backing up at 3 rotations, if I’m getting it right.
Disks are cheap though. Get another terabyte disk and play it safe
