17 Online Data Backup & Synchronization Tools

Bad things happen to good people.

Despite their sizes, laptops get nicked, dropped or misplaced all the time, and research says that out of the 2 million laptops that get stolen every year, only 2% are ever recovered. The main issue for most is not that they have lost their hardware; it’s the toil that goes into amassing the contents that really gets to them (and all of us for that matter). Assignments, proposals, song compilations, family pictures – all gone in the blink of an eye.

But it doesn’t have to be that way.

Technology can now afford to help you keep your important documents and files through a cloud system. The concept behind this is that an off-site data storage facility auto-synchronizes and backs-up your files for you via a remote server. This way, even if you lose your machine, you can still access your files through another. These also work great as a file-sharing tool for extremely large files.

After the jump, check out the best of online data backup and synchronization tools.
