I have a lot of stuff on my hard drives. Not all of it is entirely necessary. I have dozens of old 3d studio max files and other projects that have long since been completed or abandoned over the years.
I like the idea of having an off-site backup of non-mission-critical data. When I heard that Microsoft increased their online storage capacity on SkyDrive to 25GB, I became very interested. They have a cap on the filesize, 50MB per file. To work around this, I elected to use my favorite archiver — WinRAR.
