Online Backup putting load on CPU

[Harris]

My external HDD is showing signs of getting ready to fail. I can get online backup service such as Carbonite for a couple of years for about what I would pay for a new external HDD. My understanding is that Carbonite which, if used the way they recommend (continuously), puts a steady load on the CPU. I was wondering if anyone has any experience with this type backup and if it slows down flight sim if used at the same time.

I can only imagine that if it's a continuous BU, that it's always sending and receiving data, and that would imply to me that, yes, it will always load your CPU. How much probably depends on the packet size, and I'll try to learn a little more. There may be ways to perform backups at a scheduled time, rather than constantly, and that might be better. It may be easier to just plug in a new HDD and move it from the external to one in a bay inside the box, if you got room for it...

And, even though it's probably all secure, and everything, I don't know about storing my stuff with an online thingy. Just a thought... :-/
