Open Source Alternative to Microsoft's File Replication Services [closed]

Solution 1:

rsync

there is a mirror option for it. much like robocopy & it is opensource & there are windows binaries!

Solution 2:

If you wanted to cobble something together, I suppose you could use robocopy (http://en.wikipedia.org/wiki/Robocopy) to mirror your fileshare to a secondary location, but for multimaster replication (where users can add/remove files in either location and have the change be reflected in the other locations), FRS is really the way to go.

Even better, if you are running Windows Server 2003 R2 or later, use DFS (the successor for FRS) that has some neat new features above and beyond what FRS provides (http://www.microsoft.com/windowsserver2003/technologies/storage/dfs/default.mspx)

I know this is not for Windows but you may want to check out DRBD. If you use conventional ext2/ext3/reiserfs filesystem, you will have an active node and a spare. If you use more powerful OCFS/GFS you will have an active/active cluster. This is very efficient.
