Time Machine wants to backup all files after permission change — how to avoid? 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.
In the end I just had to erase my time machine disks and start from scratch.
It seems to work fine now, but this is not how it should have worked.

So I would be looking into moving from Time Machine in favor of something more reliable and avoiding TM further at all costs.
