I typically find drawing recovery to be a big freaking waste of time.
Get in the habit of real saves. I don't care what program you are using- Word, Excel, Corel, AutoCAD, Civil 3D of any version, etc.
Save for real.
If real saving takes too long- there is something wrong with your drawing, the way your data is managed, your network, something else.
Save for real. If you crash, shrug it off and skip the recovery. I have wasted more time that I care to keep track of waiting for a drawing to recover only to have it NOT recover. I could have redrawn in that time and been back to normal.
When parceling, I do a real save every five minutes or less. Autosave contributes to more parceling crashes than it fixes.
I do, however, like .baks.
