Recoverpoint For VM 5.3

Hi Team,

Can someone help clarify something about the journal and the Repository.

I just deploy a nex vRPA cluster and just specify a repositore for eac h vRPA cluster on each site, but i didn't have mount any volume on ESX for the journal. 

Want to know if is there something wrong?? i watched idan Dell EMC engineer on youtube and not saw a part where he configure volumes for journal.

Is there a difference between Journal and Repository??

Help will be so much appreciate.Thanks
