Backing up your drawing files is highly recommended because computer environments, hardware, operating systems, software, and operators are not 100% dependable.
Here are a couple of ways to back up your files:
1. Copy your completed drawing files to a back‐up folder within your own computer. This is the quickest way of protecting your files. Using a second hard drive in your computer as the back‐up storage drive will protect you if your main hard drive fails.
2. Back‐up files on a removable disk drive or USB drive.
