CrashPlan is a free-for-personal-use backup solution for performing backups of personal data, (all file types and sizes) including video to other computers and external drives.

You are provided with 3 options for backup - your local drive, a trusted computer, or the CrashPlan cloud (which is a paid subscription) or all three. The first 2 options are totally free and enable fast backup to an external drive without worrying about data caps or network speeds. Double-down by utilizing multiple offsite locations, such as other network computers or of friends and family in order to keep your files safe in case one location becomes compromised.

CrashPlan can work in the background automatically protecting all your important files via a simple configuration process that contains multiple settings to make backup a breeze - set your auto-backup frequency, configure the network, and set up CPU thresholds and more. It really is computer backup made simple.
