HyperV Replication RRS feed

  • Question

  • I have a 2 server cluster, FiberChannel DAS.  Less than 3 TB total data on CSV, so NOT a huge shop.  2 HyperV hosts with 8 total VM's, 4 running on each server.  HyperV host at remote site for VM replication.  No known issues with setup or configuration.  I am at this time only replicating 3 VM's.  We had to remove the replica host from the datacenter because the cost of data overages was going to get me fired.  We were seeing almost 3 TB data a month.  Opened TechNet support ticket and were not able to find any issues to explain the inordinate SIZE of data being moved.

    I know that from time to time the VM's are resynchronizing instead of simply replicating, but I don't know why this is happening and I don't think it explains everything.  At this point i'm wondering how many people are using HyperV to replicate to an off-site server??

    With the bare minimum 3 servers I am currently replicating I see 40 to 80 GB of data a day.  Over the course of the last 2 weeks the average amount of data pushed to this server is 58 GB per day, which runs in the neighborhood of 1.8 TB per month.

    Industry software package with SQL backend and front end server.  FE have very little config and rarely changes.  The main db is roughly 300 GB in size.

    The 3rd VM being replicated is a sharepoint server, again, small shop with about 70 employees, this server changes very little.

    As I mentioned, the MS HyperV support team crawled all over my servers and declared my configuration to be correct.

    Anyone else see this kind of volume on replication traffic?
