It's not your fault that NAV 10 is the monster that it is, Dan

But, manually disabling will definitely do it.

I just finished a full backup with auto-protect disabled and it seemed to go normally.

My backup routine is becoming a bit cumbersome though.
-Log out of primary user account (since I am using filevault for that account)
-Log into alternate admin account
-Remember to disable NAV auto-protect
-Log out after backup is finished
-Log back into main user account
-Remember to re-enable auto-protect (sometimes it is in a nice enough mood to offer to turn it back on for me...)
