Time Machine bug 26.6 Beta

[QINirvana]

Backup disk not available error when attempting to back up after upgrading to 26.6 Beta. The backup folder is mounted and accessible. Please do not upgrade if you rely on Time Machine to back up via network/NAS.

A simple reboot might fix this. If not, try deleting the backup folder as a destination and adding it back in.

I rebooted my Mac and NAS, deleted the old backup folder and created a new one, played with SMB settings on the NAS, nothing has worked. You can read and write to the backup folder from the Mac, but Time Machine fails with the message "Backup Disk Not Available." I submitted a ticket.

Interesting. It’s still early in this beta phase.

I’ve tried almost every method I can think of (including your advice), but I still can’t get it to work. I can’t back up, I can’t downgrade — all I can do is wait for the next version to fix this issue.

I’ve tried the same steps you mentioned, but unfortunately, no luck on my side either. all I can do is wait for the next version to fix this issue.😂
