Feature Request - Backup .db file

[Tahlor]

I got an error something to the effect of "Error with JSON "N" at position 8345", presumably caused by my manually editing the code for one of the base learners. Once I got this error however, none of the base learners in my project would load. I resolved it by manually deleting the base learner I had been editing from the .db file. I'll post the specifics if I can recreate it, but I'm wondering if it might be prudent to have some kind of db backup/"Last Known Good Configuration"?
