Question about networked computers

Suppose I have 2 computers, A and B that are networked. I want to backup a folder that is on A and put it on B (so both computers have access to the folder), but I want those folders to stay the exact image of each other.

For example, if I'm on B and make a change in the folder, I want that change to happen in the folder on A too and vice versa.

So, is it possible to do this on Windows?
 
Is there some reason you don't just want to share the folder and be done with it? If you just want to have a backup of the folder, then use a CD, DVD, tape drive, or similar removable media. But synchronizing folders is exactly the kind of ugly hack that file sharing is supposed to avoid.
 
Yeah, I know it's kind of bizarre, but the guy I know needs it for his company and wants to have 2 distinct, up to date copies. I will propose him to just share the folder, but he was pretty insistent on the fact that he wants it on 2 drives...

Maybe the 60$ for the software mentionned above will make him more "receptive" to my arguments!! (60$ is not cheap when you can share a drive for free 🙂

its raid 1... its write to both drive at the same time.

Networked raid 1? That's so different from what he wants I don't know where to start.
 
You could probably do networked RAID 1 with the Linux nbd driver, but I havn't tried it and it's not applicable to Windows.

Yep, it works, but raid is not at all what he wants

nbd is the Network block device, so it would do what he wants.

No, read the original post. He wants a clustered FS, not an FS that will suffer from having one machine turned off.

your confusing striping with other forms of raid. raid 1 is just mirroring, it doesn't suffer from a single failure. What he really needs is DFS since he uses windows, however that would require at least two servers.

I actually wasn't suggesting networked raid, just normal raid 1 in one machine (easy in windows) and share it out to the other machine. He said the owner wants the data in two places (I was assumiong for redundancy only) and this would therefore fit the bill cheaply and easily.

anyway...

 
No, once any raid array is broken, it needs to be rebuilt. it suffers, it just doesn't die. He wants both machines to have a copy of that filesystem, as he said.

Need4Speed thanks for great link. I've been pondering something like that myself and long since lost a similar program I was going to test out. Appreciate it!
