If you need a simple backup scheduler, give Code 42’s CrashPlan a try. CrashPlan is available for Windows, Linux, and OSX and allows file backups to local, networked, and off-site locations with a simple, easy-to-use setup.
Download and install CrashPlan Free to each computer you want to backup and one the machine you will use as a backup server. You can have any number of machines connected to your “cloud” with the only limitation being the available space on the server. I have it backing up my Macbook Pro and VCR to an external hard drive connected to the VCR. These backups are also mirrored in an encrypted folder on a computer at my office across town.
Cloud backup storage is also available from CrashPlan for a nominal fee, but with off-site storage being as easy as connecting your work computer, I don’t see much need for it.
