Firstly I have searched Super User and not managed to find any questions exactly like this so apologies if it is a duplicate..

I am looking for a (preferably open source) system which I can use to sync files across multiple machines (all windows based). Dropbox goes a long way toward what I would want however I'm not keen on the fact that it only syncs one folder and I also am trying to avid third party services (security is important). I am looking at building one myself however before embarking on this I thought I would see if there is anything that already fulfills my requirements:

  1. allow me to use my own storage (this storage can be Amazon S3 however it would be MY Amazon S3 account)
  2. Allow syncing across more than 2 computers
  3. Ideally a web-based front-end to the files would be available which I could install on a web server, although this could be handled separately

Does anyone have any experience with anything like this?

Get a look at Unison: http://www.cis.upenn.edu/~bcpierce/unison/

I don't think it has a web gui though.

I have checked it out before - only seems to support 2 computers though –  Macros Sep 11 '11 at 12:02
I thought the scenario was a bit different. When you mention S3 I think of many clients syncing with the copy on S3, but Unison can't access S3 by itself (or at least, it seems so). What about freshmeat.net/projects/superflexible the superflexible file synchronizer? It's freeware but not open. –  David Costa Sep 11 '11 at 12:09
