With IDPA, only meta data is stored in Avamar and customer data is stored in Data Domain. There is some replication already setup between Av and DD, but when customers speak of replication, they usually refer to customer data between DD systems, usually at different sites to provide DR. Below is a good place to start as it describes the replication architecture options (Ch 4), as well as CDR (Ch 5) and Cloud Tier (Ch 6).  It is not specific to IDPA, but IDPA is essentially a hyper-converged AV/DD solution with extra tool thrown in, so Avamar and Data Domain references generally apply to IDPA as well.  This is an example but you should search Dell Support for your version. Dell EMC Avamar and Data Domain System Integration Guide: [URL]   Questions/comments welcome. If you found this useful please give KUDOS to help others find the information also. thanks
I am trying to setup a replication policy to copy of my backup data to a DR location. I am trying to use Azure blob storage, though I have also tried setting a replication to another server on another site.  I assume everyone has a DR copy stored offsite? How are you accomplishing it?
