We have a simple 2 x server workplace.
Server 1 - Windows Datacentre 2016 - Approx 20 x hosts running on MS Hypervisor.
Hardware - 2 x 20core CPU's, 384GB ram, 4TB SSD, 6 TB SAS.
Server 2 - Windows Datacentre 2016, Approx 3 x live Hosts (DC2 / Veeam / WSUS) running on MS Hypervisor.
Hardware - 2 x 6 Core CPU's, 384GB ram, 4TB SAS, 8 TB SATA. - + 4 x External 2TB USB Drives
Network - Server 1 and 2 are in seperate buildings connected via a 1GB Fibre link, link is somewhat contended during the day, but clear overnight.
Currently we have configured Veeam B&R for replication from the primary server to the secondary server. We have 2 x pools for the replication (Critical and Lower Priority)
Critical is replicated every 2 hours from the SSD to the SAS primarily, with 7 days worth of replicants.
Lower Priority is replicated every Day from mainly the SAS to the SATA.
We currently have a weekly backup job running from Server 1, to the USB devices attached on Server 2..
I am looking to backup from the replicants on server 2, instead of creating new backups from the primary server. This will hopefully avoid the backup slowing the primary server, and will reduce the effects across the fibre link. Obviously the USB external drives are a bottleneck as well, so the backups run for an extended period..
Can we backup from the latest replicants? (Reverse archival from the replicants effectively?) How would we configure this?
Thoughts and suggestions greatly appreciated.
