Do you have a backup plan in place for your personal files at home.
I have had a look around today and confirmed that, in my opinion, the best on-line backup is still Crashplan: https://www.code42.com/store/
For one PC its $AU69.30 per year for unlimited data and it backs up continuously and automatically across the internet. All the data is transmitted and stored in an insanely high level of encryption on their servers.
A family plan is $165 which backs up to 10 computers if you have three or more PC's that's a good deal.
There are a few tricks for setting things up initially then there is a one time backup that copies all your data which may take a few days to complete but after that its pretty much set and forget and you get an email every now and then just letting you know that everything is going along OK.
Just be aware this won't work on a server (for business) its PC only.
If you want to work out how long the initial backup will take go here and run the test provided by another on-line storage provider: http://www.backblaze.com/speedtest/
