Is it not possible to delete files inside time machine backups (for OS 11.2.3)? There is no such option in Time Machine

You do not want to delete files in the backup— this will corrupt the TM database.

Time Machine will manage it's own db:

Hi WKC_HK,

You cannot delete files from your Time Machine backup.

Cheers,

The new version will NOT delete backups if the disk is full. I'm having that issue right now with my computer. So far the only solution is reformatting the drive.
