I have been using Time Machine on 10.9.5 for a long time now, and it was working flawlessly until today.
This morning a friend of mine tried to access a freshly set up NFS share of my Music folder, but couldn't read any files due to their permissions.
So I went ahead and ran
chmod -R 755 ./* on the whole Music folder, which is roughly 600 GB in size.
And so, now it wouldn't backup at all, telling me this:
The error message keeps on appearing, altering across my two backup disks, none of which obviously have the required 600 GB of space.
Is there any way I could tell it to ignore permissions on that specific folder, or somehow retrieve the permissions without restoring the whole folder from the last backup?
Many thanks in advance.
