As you can see from this image, time machine stopped cleaning backups from previous days and weeks.

A bit of background, this is a networked backup for a MacBook Pro. (Thus, the backups only happen when I'm at home on my home network.)  The MBP: OS 10.8.4 2.4 GHz, 8 Gb: 750 Gb drive, currently using 125 Gb - 625 Gb free.


The time machine "drive" is a 350 Gb partition on a 1 Tb drive, 75 Gb free; the other parition has the time machine backup for another MBP, also OS X 10.8.4; this problem does not occur on that time machine partition with that computer.  The problem started on 5/12 with previous days multiple entries not being deleted. (The timing does not seem to align with a software update: 10.8.3 on 3/25 and 10.8.4 on 6/6.)


One more thing, backups take much longer (around 25 minutes for just a few Mbs) than they do on the other MBP which uses the other partition. The other MBP has many more files and folders and the .sparsebundle is bigger (252 Gb).


I have read through Pondini's wonderfully thorough website on time machine ( and looked through discussions here. All seem to focus on ways in which time machine prunes old backups to make space. In my case, space is not (yet) a problem, but I am concerned that these problems indicate time machine is not working properly and that there may be other problems.

MacBook Pro, OS X Mountain Lion (10.8.4), 8 Gb memory 750 Gb disc
