A few years back, I remember that I stayed back in the office to update the inventory system because all the data in the backup went missing. Because of the urgency of it, I even brought the CPU home.
If you do not want the same to happen to you, I would suggest Tilana for Continuous Data Protection (CDP). New and modified files are protected automatically as you save. And if you are working on different computers where remote file access is required, this is a software for you too. It will also help keep your file sync. Any file protected in the remote data center is available to sync between your computers.
