We are about to setup Backup Copy Jobs from our primary VBR server to at repository at another site. The two sites are directly connected with a MPLS.
Both the primary VBR server and the offsite repository are running Windows Server 2016 and the disks are formatted with ReFS 64K for space savings.
If I enable encryption of the backup files in the Backup Copy Jobs, will that hurt the internal deduplication and compression that VBR uses? Will it take more space when VBR utilizes the ReFS "magic"? Space savings are important to us, but the secondary site is not as well protected as the primary site, so encryption would be a nice thing to have.
