I don't even know what "APFS" is; I searched for why my Time Machine is suddenly backing up SO SLOWLY (14 hrs now--& it's only 20.1% backed up!!). The article said I have to DELETE my entire back-up drive, & reformat it to this "APFS" thing. Of course, I CAN'T wipe out my back-up drive! I'll have to format another drive with this new format... What's going on? Why does my MacBook Pro (on Monterey 12.6.6) not want to back up any more?? (And 14 hrs to back up 20% is UNACCEPTABLE in ANY format!) Thank you for your reply.

I thought My Backup Plus was some third-party backup software. I guess it is the type of drive?

I don’t know why it is so slow.

Take a look at System Information, USB, to see how fast the drive is connected. It may be connected at USB2 speeds. That can happen if the drive is connected through a hub and there are USB2 devices attached.

The file system format won't make it back up any faster, but yes, you can use APFS.

How much data is being backup up? If this is the first time making a backup, then it may take a long time.

Also, is this a new drive or an older drive? Maybe the drive is failing or just worn out.
