Sacred Haven of Debauchery

At work, I have an auto-backup feature set up in one of the programs I use. Considering that the program tends to occasionally freeze and crash, it's a useful feature. But at home, I don't bother with that; I usually just keep 3-4 versions of a file in different formats at different stages. For example, for my current project. In one program, I draw the page itself, in another, I set the color palette, add text, and create special effects, and then I upload the PNGs to ArtStation, VKontakte, and other places. I also have JPEG scans of sketches from the very early stages, but they're in a separate folder.
And yes, just a reminder xD
