Comment 5 for bug 1332969

One detail I only realized now is that the btrfs-formatted external HDD to which I'm doing the backup is almost full. It was 95% free according to df, but that's not a very reliably model so I didn't pay much attention to it. Trying to recreate the large snapshot completely filled the disk now, and caused backintime to start erasing old backups, so now I'm at 86% according to free. Attaching a (slightly redacted) log. During the backup process and the consequent automatic backup delete memory usage stayed around 20%. Will try to see what happens when I try to delete the latest (partial/failed) snapshot and report back to you.
