My Time Machine disk is full. Time Machine is supposed to clean up old backups, but it doesn't. Previously i deleted the backups manually, but this is supposed to be Time Machines tasks.

Hi there,

You should never manually delete Time Machine backups. If you are out of space, taker SeaPapp’s advice and erase the disk and start over, or get a larger drive.

If you need a larger drive, I always recommend the G-Technology G-Drive USB-C 4TB: https://shop.westerndigital.com/products/external-drives/g-technology-g-drive-usb-c-usb-3-1-hdd#0G05666-1.

You cannot really stop it from happening. Time Machine is designed to backup often and always have lots of backups and history of your Mac. If you get a 4TB G-Tech G-Drive (see link above), you may never fill that drive up. It will last you a very long time.

Cheers,

Time Machine is a wonderful backup utility, sometimes it doesn't act as we'd expect for whatever reason. Manually deleting backups if not done properly will cause problems. While this is a very dated reference you may fine some help here http://oldtoad.net/pondini.org/TM/C4.html

This site does not mark posts helpful or solved, only you can do that.

Easiest solution is just to erase the Time Machine drive and start a new backup set, or buy another drive and start a new backup.
