Time Machine backups

RE: My MacBook Pro...

My time machine has been backing up for over 18 hours! I back up weekly. Set it at night and it's usually done by morning. But...the last time it was sill working after 24 HOURS so I finally had to eject it. Now it is over 18 HOURS...so what do I do??

MacBook Pro 13″, macOS 12.6

Your internal drive is an SSD. these tend to fail suddenly when they fail.


Your backup drive, if a rotating Magnetic drive, may be developing more and more Bad Blocks and getting ready to fail.


I suggest you obtain another backup drive, and ADD it to your Mac as an additional backup destination. Your Mac will alternate drives, every-other backup goes to every-other drive, until you decide to stop using the old drive.


Your new drive will be a new, stand-alone backup set, starting with today, and all your older stuff will be on the older drive.
