Backing up remotely, online, via the Internet has a couple of great strengths, especially for home users, students, and roaming laptop users. This is the ability to back up wherever you are, whenever you are connected to the Internet. There is no need to haul a backup device or media around with you, have it connected, and run a backup session every day. Online backup solutions check for and send changed files over the net whenever your PC is idle, (or at a time you select). Local solutions could do this too, of course, but then you must have the storage device with you, and connected all the time. A related big strength is the ability to restore from anywhere that you have Internet access, anytime.
Robert Ellison, CEO of Cucku describes some of their online backup options:
"Cucku Backup supports external, network, flash and many other devices. Cucku supports removing unwanted files from both local and remote backups. You can purge files that have been deleted and also files that are no longer included in the backup set. This prevents the common irritation of needing to start a backup from scratch in order to reduce the backup size. For remote backup Cucku allows you to send backups on an external hard drive and then new and changed files over the Internet, repeated if needed. This hybrid approach solves the upload speed problem inherent in most online backup products."
