I run a system that has multi site replication to multiple Artifactory instances all replicating from one single Master to all Spokes. Each one can hold up to 2PB. While Artifactory supports writing to a backup location, given the size of our artifacts, we chose to not have an actual backup. Just live replication to five different sites. Never have tried to restore or replicate back to main. I am not even sure how that would work if the spokes are all “*-cache”. Backend storage for each Artifactory instance is Dell Isilon.
