CrashPlan is a free online backup service which offers quick and easy file storage plus. The plus bit comes in the form of a clever feature which lets you back up files to a friend’s computer or to another computer on your network. This effectively gives you peer to peer archiving with a simple user interface.
The free version is advertising supported, although if you make use of their online server option you will pay $5.00 a month for 50 GB storage. Of course the big issue with online storage, as the company admits, is it’s pretty useless for large scale archiving above a few gigabyte, so local or P2P is a nice free option that most people will probably use. If you’re in the market for a backup solution, then this is definitely worth a look. Cross platform - Mac, PC, Linux. And Solaris!
With CrashPlan you have the freedom to choose your backup destinations. Back up your new Mac to your old PC, your laptop to a friend’s desktop, whichever you want. Worried about using too much space on a friend’s computer? Just attach a USB drive and back up to it using CrashPlan.
