Hello (i dont know the right name - sorry)

Thanks for fast Reply !

Now i understand it - so i build a Gluster System on the other side with
enough Capacity then i arrange a Geo Replication between this 2 Gluster

A other Question regarding this issue:

In documentation i allways see SSH to use for Connection between the both
Gluster Setups.

In my case its also possible to build a VPN between sides so can i also use
direct IP Connection trough a S2S Vpn ?

Best regards
