It's not 'real time' but you can achieve something like this by using a combination of ZFS snapshots and ZFS send / receive. Would that be rsync with just a frequently scheduled cron task? Which works very well indeed in many situations. Someone else has already mentioned distributed filesystems line AFS -- another thing to contemplate is the new HAST capability in FreeBSD: http://wiki.freebsd.org/HAST It's conceptually similar to Linux DRBD, which in theory you can use under FreeBSD as well, but no idea how it performs.

RE: FreeBSD equivalent of Microsoft DFS
for all: MS DFS = MS Distributed File system is NOT a FS it's a shared directory on a drive that is replicated via AD mechanism to 1 or more locatations If setup correctly DFS can have 2 or many more servers, and to replicate it only needs a partner server to replicate with. all other servers can be turned off .. its neither a ring or a star shaped network. (not 100% true but makes explaining a lot easier) In Freebsd that woud be a CIFS or NFS share that is synced over 1 or more sites (without bandwith control ) The only issue if you want to replicate this within Freebsd is how to setup the sync process for more then 3 hosts. And more specific if 1 file gets edited on to seperate servers and replicated to a 3rd server, what happens then? Of course such a write action when it happens is very very small chance. IF you want to use FreeBSD as a file server for a windows enviroment (with ZFS) you can do 2 things 1) use ZFS and make a ISCSI -disk (istgt port for now) and connect the ISCSI disk to a Virtual server with a windows server host 2) use ZFS + SAMBA, configure samba to use the AD information to give access (Single Sign On) The first one is the easiest fastest way however it will cost you performance compared with the second solution. The most difficult is to have samba connecting to a AD enviroment without any alterations on the windows machines/ad and kerberos. However SAMBA AD are reported to have a love hate relation ship working together, and can break Date: Mon, 9 Aug 2010 15:42:59 -0700 From: edfle...@gmail.com To: freebsd-questions@freebsd.org Subject: FreeBSD equivalent of Microsoft DFS Is there a FreeBSD equivalent to Microsoft DFS, i.e., software that will replicate delta level file changes of network shares among multiple servers in real time?

A distributed filesystem like Coda[1] or Andrew FS[2][3] would be better. Not sure about there FreeBSD support.
