Time Machine Backup

I recently upgraded from Majove to Big Sur. Now Time Machine has a backup of both systems on it. Could I delete Majove? Every backup is lasting forever now, even when I just made some minor changes since the last backup.

If you are sure you no longer want or need Mojave I would erase TM drive and start over fresh. The first backup will take a while but then after it will only do incremental backups as needed. The backups should only take a short time.

With the drive connected if it shows as TM then go to preferences, TM, select disk and then click on the disk and then click remove.

Then open preferences, disk utility and select that disk and click on erase. Name it Time machine, Format to APFS. This will now make a clean drive. Go back to Preferences, TM and select disk and pick that disk you just formatted. That should work.

Thank you so much for your prompt response. I would gladly erase the TM drive but how do I do it? I have it on a "WD Passport Portable Drive for Mac".

Thank you very much. That’s what I did after you suggested to erase the drive. Earlier, I rated your answer as “solved.” Thanks again.
