Any suggestions about how I might recover previous versions of a doc.which could not be recovered?

Libre has not been able to recover my doc. after an automatic shutdown despite automatic saving. It can only recover the original doc. Libre also recovers untitled docs. but not changes to the important ones I had been working on. Thanks for your consideration.

p.s. This is the second time this has happened. And can I trust this advice about disabling auto. shutdowns?
