Time Machine Backup Failed

TM can delete normal small incremental backups to create room for a new small incremental backup, but when the drive is full.......and......you have a larger than normal amount of data to back up, TM falls down and sends the message that you are seeing.

You really only have two options here.

1) Add another drive or Time Capsule and start TM backups going there.

2) Erase the existing drive and start over again with a new set of backups

A third, but very poor option is to try to manually delete older backups. This will take many hours, and very little space will be regained, so it will not be long before you see the same message again. Definitely not recommended.

I have been getting the following message:

Backup Failed

There isn't enough space on "TimeCapsule".

I have two Time Capsules, an old 500 gb one and a newer 2TB one. The backups alternate between the two.

I'm guessing the reply you gave to the OP would be true for me as well? I need to erase the drive on the 500GB Time Capsule and start fresh?

Thank you for your time!

Yes, erase and start over.. since you have two backups this is easy.. can I also suggest using a USB drive plugged into the gen1 TC because it probably is too old and too sick to keep going much longer.

The 500GB is also too small a drive and will fill up again pretty rapidly.
