No, I don't want to use RAID at the moment, instead I want a software or a script which can constantly sync folders on one hard-drive to a second physical hard-drive on my PC or any other PC on my internal network.

And if that network PC is not available to schedule it to copy to it the next time it comes on.

The reason I need this kind of a solution is that as a family we have a network of PC's and collectively a lot of empty space on each other's computers that can be used for collective backups.

Another feature which would be largely appreciated would be if the space used for backup's can be protected from accidental deletion and can only be deleted by a passworded account or some other protected means.

Basically if the software would allow me to visualize all the space that could be reserved for backup's as one drive and allow for backup's to DVD's when the data crosses a particular limit I set. Seems like a dream backup strategy to me as this would allow me a rock solid backup setup in an automated fashion and that to without use of any additional resources. Any ideas on this? Would appreciate any sort of ideas which would throw some light on this issue.

In this question: One of the comments talks about using rsync. I'm not sure if this will work for your purpose but it's worth a look. – 에이바 Sep 27 '10 at 20:43
but this is for UNIX based computers and I use windows and seems like a hassle to setup, would prefer something with GUI definitely. – rzlines Sep 27 '10 at 20:46

I realize that their heavy use of FREE makes this sound like a serious ad. I'm actually not assiociated with them and actually haven't started using their product. Best of luck! – fideli Sep 27 '10 at 21:39
sounds good but does let you combine all the storage space you have on your network or at least show it to you as one drive even though its not? – rzlines Sep 27 '10 at 23:35
I have no idea, unfortunately. – fideli Sep 27 '10 at 23:59
No, it doesn't. Each computer you install the client on will show up as a separate location to backup to assuming all the clients are connected using the same CrashPlan account. – Ryan Bolger Sep 28 '10 at 0:25
