As far as host-based replication tools that work on the file level, Replistor is just as good as any other tool.  Do they have a HyperV module to replicate the VM files?  I had it running for several years and we switched to a Celerra because it just couldn't keep up with the millions (and millions and millions) of files we were replicating ... all host-based tools have their limits.

A customer of us is using a AX4-5i and is looking for a solution to replicate it's environment to a remote site. The AX4-5i doesn't support Mirrorview so he's looking for another solution.  He's got a couple of hyper-v servers connected to this AX4-5i via iSCSI.  So if we want to replicate via Replistor, is that supported in a hyper-v environment and does anyone have any experience with this kind of setup. I'm a bit concerned that nothing is happening with Replistor, last manual update is from 2009, is there still some development in this product taking place.  Regards, John
