XDCR is available for community edition, then we should expect that all the feature are available.
Without working backup process, why don’t you allow community edition to pause the replication stream by REST API (it is available by the web console) ?
(see my post on backup issue)
I read several post on this forum and the most common way to backup a cluster is to do it with XDCR …
Do you have any (working) method to backup a cluster during a specific period ?
