Here's an interesting Time Machine (TM) problem. I had been
successfully using TM since 3/1 or so. TM works by first making a
copy of everything on your computer's hard drive; then it makes
regular incremental backups. When those incremental backups fill the
backup/TM drive, it erases the oldest backup to make way for the
newest. I reached that limit around 4/1. My computer's drive has
files occupying 121 GB; my TM drive capacity is 150 GB. Therefore
about 29 GB of the TM drive consists of incremental backups. So far
so good.
Then yesterday I got an error message that the latest incremental
backup had failed because the TM drive did not have sufficient room.
The only way this could conceivably happen is if my incremental backup
was 30 GB. It wasn't. I can only surmise that TM isn't erasing the
oldest incremental backups. But that isn't supposed to happen.
Any insights would be appreciated.
