We're currently using DFS to replicate files between 2 Windows 2008 servers. We're doing this to: 1, give us server redundancy so that we can have 100% up time despite having to patch and reboot either of the servers; 2, to have a second copy on-site so that we have a little "buffer" to hardware issues (despite these both being VMs).
MS has never heavily marketed/pushed DFS, however it's worked fine for about 10 years for us (initially with Windows 2003). We are getting some new systems that will be Windows 2012 (also VMs) and want to know if there's something preferred by MS for equivalent functionality now. We already understand these are VMs and have some resilience to H/W issues but want a solution for item #1. We need file replication along with multiple servers for OS availability.
Does MS still recommend DFS for this purpose or is there some new and improved clustering available? We know that with our newer SQL Server setups (on Windows 2012) that SQL Server redundancy is now being provided at the OS level, not within SQL Server (as least that's the MS preference).
We're not looking to introduce new products if we can avoid it.
