CrashPlans main appeal lies in the degree of control it allows users to exert over their backups. With this service, you can manage everything from how often CrashPlan checks for new file versions (from once a minute to once a day) to how frequently the service purges deleted files. Power users will enjoy tweaking the softwares performance settings, controlling how many CPU cycles CrashPlan consumes while the PC is idle versus how much it uses while youre working on other tasks, and even managing its outbound-bandwidth consumption.
With this service, you can store up to 2GB of data on a free planthats enough space for 300 photos, by Mozys estimation. Mozy also offers 50GB of storage for $6 per month (for one PC) and 125GB for $10 per month (for three PCs). Only computers running Windows or Mac OS X need apply; Mozy doesnt support Linux machines.
Mozys desktop application is dead-simple to navigate. The service can back up your data by file type (videos, photos, and so on), or you can drill down and select specific files and folders. You get no option, unfortunately, for backing up programs or the operating system. Another major drawback is that you must perform all backups online; you cant copy your files to an external drive and then ship your backup to Mozy. The services biggest sin, however, is that it permanently removes deleted files after 30 days.
CrashPlan edges out the other two backup services thanks to its extensive customization options and OS compatibility. And once again, our favorite desktop service also offers the best iPad option.
