[NCLUG] FOSS solution similar to DropBox?

[DJ Eshelman]

Greetings all,

I know I asked this question a few years ago but thought I'd re-visit it.

What I'd like to do is simple enough- I want to have a system to keep my 
files on my Windows and Linux PCs backed up to my CentOS server at my 
office, but I grow weary of 'sneaker netting' the backup drive back and 
forth, then copying the new files to the share via FTP here at the office.

What I'm really hoping to find is a nice full-featured solution similar 
to DropBox (www.getdropbox.com) that just works and is capable of 
bit-level backups (I suppose this is optional, but it'd be nice to limit 
the bandwidth required with version changes).

Of course there's Unison and a few other rSync-based products out there, 
but honestly I was hoping to have to spend a lot less time hacking away 
at it, and I need something that works well in Vista 64bit as well as 
distros like Ubuntu.  I really like the web-based simplicity of DropBox 
but I need a lot more space and I'd really like to keep this on my 
servers since I'm already handling DR for that server.

Any ideas?
