Too many free storage accounts to keep track of, try:
ORGANIZING MULTIPLE SERVICES:
The concept is pretty simple: sign up for as many free cloud storage accounts as you need and utilize each one to back up different kinds of files. The downside to using a bunch of services is, obviously, that your storage is fragmented, but I'd argue that there's a benefit in that as well. If you segregate the types of files you back up (and sync) with each service, you know exactly where to find them. For example, you'll know your photos are on SugarSync and your music is on Amazon Cloud Drive. The other downside is that you'll have a few apps running processes on your system all at once. For the most part this should work just fine so long as you don't try to alter, say, your photos and your primary work files at the same time.
