Time Machine not backing up - Backup Disk Not Available

[scouser75]

Hi Guys,

As the title says, I'm running Sequoia and am having an issue where Time Machine just will not recognise my HD.

The disk shows on my Desktop and I can open it to see previous backups, but when I try and back up it fails and I see the following message. I've removed the HD and reconnected. I've shut down and restarted. But nothing works.

How can I fix this please?

Did you try running First Aid on the volume with the Disk Utility app? It might take a while depending on how many snapshots it has to check…and what type of drive it is.

Thanks Brian. I'll give this a try now.

I ran first Aid and still no good.

I've searched online and can't find find any solutions. Really don't want to wipe the HD and start from scratch.

I think I may have fixed it.

I simply removed the disk from Time Machine in settings and re-added it.

Now 🫰
