Recovering Drawings

Sorry I haven’t posted in a long while, I have been busy with school. working full time,and still trying to maintain a social life  has left me with little time to do my post.

Anyways, the other day I was working on a large grading drawing for my subdivision I have been working on. After about  2 hrs of working the drawing crashed. I spend the next 1/2 trying to find ways to recover my drawing since I have my automatic save turned off. You may ask why I had my automatic save turned off. Well the grading PG drawings contains many road profiles and many road corridor surface for about 3 miles of road. If I was in the middle of regenerating a surface or corridor and the automatic kicked on at the same time, the drawing would crash. That's something I don't want happening. Anyways, I tried recovering the drawing from the most recent bak file. That didn't work. i tried doing a RECOVERALL and  RECOVER but it kept crashing. I looked to see if I had any temporary backups but I didn't. What I really needed was backup from the previous day or most recent. Well after a few minutes of playing in C3D i ran into this recovery system that Windows creates. I have provide a short video of how I was able to recover a drawing from the most recent windows backup below.

How Windows Creates A Backup: Previous versions are automatically saved as part of a restore point. If system protection is turned on, Windows automatically creates previous versions of files and folders that have been modified since the last restore point was made. Typically, restore points are made once a day. If your disk is partitioned or if you have more than one hard disk on your computer, you need to turn on system protection for the other partitions or disks. Previous versions are also created by Windows Backup when you back up your files.
