It says there isn't enough free space on the drive. From my understanding Time Machine wipes clean old backups before saving new backups, is that right? And if thats the case why isn't backing up?
Time Machine hasn't backup since April. I was hoping the issue will resolve itself after upgrading to macOS Monterey but clearly it hasn't.

You should use the Disk Utility. In my case, I erased the disk then removed the volume completed. I suspect that there is no need to erase before removing the volume. BTW, I only use APFS so the Time Machine volume is located in an APFS Container.

I had this happen a day or two ago after a lot of activity related to the Monterey upgrade.
In my case, I have a second Time Machine backup volume (TM2) which I usually backup once per day. My solution was to erase and remove TM1. I then recreated the volume and added it back to Time Machine. 28 backups have been made so far on TM1 and 93GB (out of 160GB) is still available.
I suggest trying to backup as much important as you can to another device before deleting the your Time Machine Backup.

You'll get that message if there's not enough free space on your boot drive for a new local snapshot. How much free space do you have on your boot drive?
Boot into Safe Mode according to Start up your Mac in safe mode - Apple Support and see if you can get a successful backup from there. Then reboot normally.
Hi, its probably easier if I show you the screenshots:
Its says 200GB available
Hi, same error in Safe Mode.
What is the total capacity of the backup drive?
External backup drive has total 4TB and my iMac has 3TB.
Open ™ Preferences and click on Options. What is the space listed for full backup?
Also does Preference state that older backups will be deleted?
Do you think I should just erase the drive and start over again?
Thanks. How do I go about erasing the TM disk?
Time Machine couldn’t complete the backup - not enough free space
