I broke my Time Machine backup by using
tmutil delete on the most recent backup. This meant that the "Latest" symlink no longer pointed to a valid location. My attempts to create a replacement symlink have failed, probably due to some sort ACL issue or a problem with extended attributes.
Here is an attempt to recreate the symbolic link:
DeepThought:DeepThought cclark$ sudo ln -sn ./2020-12-20-161820 Latest Password: ln: Latest: Operation not permitted
Has anyone ever recovered from this situation?
I have tried disabling SIP, and have made sure that Terminal has been granted Full Disk access. I have also tried creating an alias using Finder, which was successful but was not recognized by Time Machine.
The backup is on a Synology NAS.
