Differential Replication

Post by Fox54 »

Hi,

I have 1 ESxi server that i replicate the VM on an ESX server ESXi->ESX

I am running without the proxy (agentless). Is there a way to replicate only the data that has changed instead of the full VM ?

If not what is the correct setup to have only the data that has changed replicated ?

Thanks

Alain, it is exactly the way Veeam Backup works. After first full replication completes all subsequent replication runs transfer only changed data and no full replication will happen again.

To elaborate this answer a little, in case of VCB, or agentless replication modes, VM replication traffic is as follows.

[VM] >>>FULL>>> [VB] >>>DELTA>>> [ESX], where site1 is red, site2 is blue, WAN connection is green.

So you want to install Veeam Backup proxy (VB) in your source site, this way all WAN traffic will be deltas only.

I setup replication for the VM

But it seems that the all the replication take the same time to complete and it seems that it transfers all the size of the VM.

I am not using the Virtual Center.

What am i missing ?

That's the way my setup is done

Maybe i am misled by the report. I don't see the volume of data (deltas) that was transfered to the ESX host

These details are not available from session report at this time, but you can see the amount of incremental data for the given replication cycle by looking at the corresponding VRB file size created during that cycle.
