Hi,
Ever since I upgraded the OS to Big Sur I have been having issues with my backup on Time Machine.
My setup is as follows:
- I have a windows server 2016, which shares a folder via SMB
- Inside that folder I have sparsebundles for each MacBook
- I first mount the shared folder
- Then I attach the sparsebundle
- After it shows as a disk I start the Time Machine backup
- The process runs for a while, random time, then I see the backup stopping and the sparsebundle disappears
- If I repeat from step 4 I observe same behaviour but it takes a different amount of time for the stopping to happen
What I did next was I uninstalled Avast Security, mounted the drives, started the backup and it successfully completed without stopping or sparsebundle disappearing.
Any help would be appreciated. I love using Avast and want to continue using it, but I also want to be able to backup my MacBook.
