Hello Forum,
We have two FreeNAS setup over the Internet (two different locations - Location A and Location B. Both FreeNAS are running version::
FreeNAS-9.10-STABLE-201606270534 (dd17351)
What we are looking for at this point is block level replication to occur between the two FreeNAS boxes where our expectation would be that the transfer of the second virtual machine backup would be done quick (since at the block level not all that much has changed). What we discovered though was that the replication task took over 4 hours to complete to move the second file. Basically it took twice as long to move the second backup using replication task.
How do we know that replication at the block level was being used? I'm guessing here but based on the time it took for the replication to finish..it seems more like freenas is acting like rsync where it has double check each block?
Is replication at the block level in FreeNAS expected to be slower or should our experience have been much quicker?
Any advice or pointers you can give would be greatly appreciated.
Thank you.

- We connected both FreeNAS over SSH and confirmed that the connection is made between both FreeNAS is good in that we can both see each others disk in Storage > Volumes.
- At Location A a replication task was successfully setup.
- At Location A a large virtual machine backup was placed into FreeNAS of roughly 20 GB large. Over 2 hours we could see that the entire file was successfully transferred to Location B FreeNAS.
- A second backup was taken of the same virtual machine. Nothing really had changed on the virtual machine but the filename of that second backup would of course be different.
