Early last week I noticed that Time Machine had suddenly stopped backing up to my WD NAS drive. There were no recent changes that occurred before the problem began as far as I am aware. Nothing in my physical or network environment changed, I had not installed any new software, and I am not aware of any macOS updates having been performed.

I've attached a screenshot of the message I am given, indicating that the backup disk is not available. Within the same image you can see in Finder that I am connected to it and can see the 3 volumes within it. Time Machine was backing up to the TimeMachineBackup volume previously; I've since deleted the backup from there, thinking perhaps I could start fresh, but the issue persists. I have no issues with accessing data on the volume that has my name on it.

I have tried the usual steps of restarting all devices on my network. I've gone into my drive's settings on WD's website and made sure that local access was enabled. I changed the username that I connect with, thinking maybe there was somehow a Keychain or other password/credential issue, but nothing has changed.

If this suddenly occurred as a result of a macOS update, or even a beta update, I would understand. I'd just wait for Apple to issue an update and go about my business. As this occurred independent of any update, to the best of my knowledge, I'm not sure the best way forward. As I have 4+ TB of data on the NAS presently, wiping everything on it isn't an option for me at this time.

Any suggestions are welcome.

Thanks in advance.

26.6 is a beta.

Time Machine to networked drives (over SMB) is broken in this beta.

If you search the beta thread, or just search this forum generally, you'll discover others with the same issue. Including me.

Any idea why it may have happened under 26.5.x or whatever the lastest version was before 26.6?

Either way, I guess I'll just have to wait for the next update unfortunately.

Mine was working on the latest public release. One of the previous MacOS 26 versions broke it, and it stayed broken for a while, but it was working for me prior to installing this latest 26.6 beta. We're due another beta early this week, so I'm hoping it'll get fixed.

Of course, you may have a different issue, but whatever it is, there's no point trying to fix it on 26.6.
