Since the 10.0.3 update around 6am this morning, every Time Machine on Big Sur 11.2.1 backup fails. The last Time Machine backup that worked was around 5:30am.
Once the backup failed because target disk could not be found, the rest of the failures had no error listed. I've rebooted the NAS and rebooted the MacBook Pro multiple times. Nothing works.
Any suggestions?
thank you for performing these tests. at this time I have a few ideas what could cause the failure. form experience, SMB volume access can be disturbed by open file handles (for example our scanning process) and then abort current operation with "file in use" - I am thinking of a better detection and exclusion of time machine volumes shared via SMB. Could you also make sure that the "remote files" option is turned off (while real time scanning itself is enabled in your Threat Protection policy.
