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.
