Small businesses often forget the importance of backing up important data files as most of their time is spent growing revenues and cutting costs.  Both Mozy and Idrive offer a couple gigabytes free for personal or very small business use (this would be good for at least your Quickbooks files) but are limited to Windows based machines.  Unlimited personal use plans are also reasonably priced from these two vendors.

However, being a proponent of open-source programs and software, I expanded my search to find a company that at least supported a Linux solution.  It appears the standard solution is rsync.   Even Ibackup, the other provider I found uses the open-source rsync utility to facilitate Linux backups.

 So, no matter your machine’s configuration, make online backups part of your daily routine to ensure that no matter what calamity may strike, your business will be back up and running smoothly.
