Time Machine couldn’t complete the backup

Why is the Time Machine not backing up:


The backup disk needs 220,50 GB for the backup but only 1,82 TB are available. Select a larger backup disk or make the backup smaller by excluding files.


any tips or hints?

Erase the TM backup disk. You will probably want to obtain at least one additional, redundant Time Machine backup disk before you do that because you never want to be without a backup, even for a short period of time. One and only one backup device does not comprise a robust backup strategy anyway.
