Big Sur, Big Problems with Time Capsule

Folks, who else is having issues with backing up to Time Capsule with Time Machine after upgrading to Big Sur?

All my older backups are no longer accessible! Everything was working just fine before Big Sur. Time Machine now keeps asking to do a first backup. When I try to do a backup, it goes into "preparing" for 20 min, then "stopping," then nothing. 1st backup fails to complete.

I tried backing up with Time Machine to a WD external drive hooked up via USB. That works just FINE. It backs up MUCH faster than before too. So I'm guessing Big Sur is having issues with Time Capsule as a networked drive??

I just discovered that "Back Up Automatically" is the only way to go for Time Capsule.

No more the need for verification before an actual backup.

But any externally connected USB backup drive has to be disconnected.

Have you noticed how many times Sophos is checking for updates?

No Sophos - never had it installed on that computer

Dec 21, 2020 2:25 PM in response to Keith14

Yep. Complete pain in the ***.

Do you have a AV like Sophos installed? If so, please remove and test. This has been the issue with the rest of us. Sophos are aware and will attempt to fix between now and the end of days.

Uninstall Sophos did the trick, I won't use it any more, installed it several times...

I have tried the latest Sophos Home Version but still no luck. Will try again upon the Big Sur 11.2 release.

Really strange. It does back up for me, albeit more intermittently. Unless they are doing different builds..

Jan 24, 2021 4:44 AM in response to Timmmmyyyyy

Ohh... I didn't get to try backing up over wifi yet, it's still doing. the initial backup...

Didn't realize that it is more inherited problems in Sophos, that sucks !

May 4, 2021 3:18 PM in response to StarsUniverse
