How can I replace DFS?

Hi Chris/Alan,

Thanks for the show!

We have two offices, one in the UK and one in Northern India. The India Internet connection is not always reliable and bandwidth is also a problem as there are phone and database services which need priority over everything else.

We currently use Microsoft DFS/FSRM on a Windows share to keep a synchronised local copy of two directories between India and the UK.

I'm trying to find a kind of two way rsync that updates in near real time or something like Dropbox that lives on two internal servers.

We send about 250MB each day in audio and pictures but do occasionally send unedited video around which can be much larger.

Could I use Owncloud or DBRD somehow or am I just over complicating things? I guess a cron job that checks every 5minutes for changes via rsync would work but I'm worried about bandwidth limits and what happens if a file takes longer than 5minutes to sync.

Backups are not an issue as the data is backed up daily at both locations.

Any advice would be much appreciated.
