So after multiple drive switches my Time Machine suddenly stopped backing up system folders. I looked into /Library/Preferences/com.apple.TimeMachine.plist and indeed there is under ExcludedByPath /Applications, /System and so on. I have tried deleting it however the time machine always restores the exclusion path. I have tried copying it to desktop and removing exlude by path value but it still got restored to original value. Any ideas on how to fix this ?
Got a tip for us?

I had kind of a similar problem, the HD I use for TimeMachine was no longer recognized.
In the end, I deleted the partition on the Time Machine HD, re partitioned it and that fixed the problem.
Yes, you will loose your existing backup, but unless you've had major changes since the last backup, that should not matter at all.

The drive is recognized and time machines backs up /Users . I have tried reformating the drive but to no avail.
This is a known bug in Mountain Lion 10.8.4.
(I had it too and solved the problem by deleting the com.apple.TimeMachine.plist file and upgrading to 10.8.5).
Did you upgrade to 10.8.5 ?

Actually I am running Mavericks now; I saw that article and tried do the reset but it did not work the time machine would always reload the plist from somewhere.
The problem is Mavericks caches plist files now. So if you make a change or delete the cached version will reappear. You need to reset Time Machine as described in that link, but reboot after you make the plist change to the cached plist does not replace the one you deleted.
Ah, well that at least explains my corrupted TM backup and why I couldn't restore from it ! Thanks.
When I looked into the TM backup when it wasnt recognised as a valid source, there was no applications folder from a date sometime in October and onwards. Pretty sure that applications were not shown as excluded in the options list when I looked.
Was able to recover as I had both a clone of my whole HD and the original machine, but shows that taking a copy of the TM disk itself isnt backup, you should backup from at least two independent sources.
