What will you do if suddenly one day you wake to see a fire has burnt away all your computers and the servers or let's say floods washed away your systems or an earth quake destroyed it totally?

Finally, you can also back up your data online if you have a high speed internet connection and can afford to purchase an data backup companies service.
You do everything on the internet anyway. Why not use web backup as well? It's the logical step. Online file backup is safe, is fast and is accessible. All you have to do is download the software, log in with your user name and password and install the application. You will then select the files that you want to be stored by your online backup service and start the back up. You can also schedule back ups, so you don't have to worry about it anymore. Everything is customizable and you can change your options at any time. You can schedule multiple back up jobs, and you will be notified when the back up starts and ends.
An additional critical backup service to be aware of is data versions. This means you actually have a history of backups available to restore from. For example, you make a successful backup of your accounting database. The next day a virus infects your computer and corrupts the database and is backed up again that night. The following day you discover the issue, but when you restore your data you end up only restoring the backed up corrupt file. If you have data versions, then you can simply go back in history to the last day or time you made a successful backup, right before your data went bad. Version history should go back, at a minimum, 7 days or versions.
