If you’ve been thinking about setting up an online account to back up to the cloud, but haven’t found the time to do the research on providers, you should know about a deal from CrashPlan.

CrashPlan, one of Lifehacker’s favorite online backup tools, is running a promotion for a free year of unlimited backup for one computer (normally $50) or for up to ten computers for nearly 60% off ($50 for the year instead of $120). Lifehacker’s post today states:

The free year includes all of CrashPlan’s paid backup service features, including unlimited online storage, web and mobile access, and backing up to friends and family.

Note that this offer is for Carbonite switchers specifically, and former or current CrashPlan users aren’t eligible. (However, all that the promotion seems to check is your email address, so I’m not sure how they know if you’re using Carbonite.)

The offer has no expiration date, but it could be pulled at any time. So if you’re looking to switch to a better backup service—for free—hit up the link below now. Once you’ve got your account, here’s how to set up your automated, bullet-proof backup solution with CrashPlan.

Don’t worry if you’re not a Carbonite subscriber. I signed up for CrashPlan today without it and still got the free deal.
