Fixing Time Machine Backup Broken by Deleting Most Recent Backup with tmutil I broke my Time Machine backup by using tmutil delete on the most recent backup.  This meant that the &quot;Latest&quot; 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.
The problem eventually worked itself out.  I think that choosing to verify the backup may have helped.
