I know this question has been asked before... vmware-vsphere-f24/backup-the-replicated-vms-t3703-15.html
, however, is it possible to backup replicated VMs with CBT enabled (using Veeam v7)?
Currently we have VMs in a hosted DC, being replicated with Veeam to our DR site (what was originally production), which is working really well. We'd like to backup the replicated VMs for the purposes of long-term retention, and we've got the backup jobs configured, unfortunately, CBT doesn't appear to work the backup jobs, which means they are taking far too long (they aren't even close to finishing before the next set of replication jobs start - replication jobs run daily). Long term, we will also have backup storage in our hosted environment, but this would be (very) short term retention only. I am aware that we could backup the source VM to the backup server in the DR environment, however I'd like to avoid shoving what is effectively the same data through our link twice, given that we already have a limited link. It would also mean, once we've got the short term retention backups working, our production VMs would be getting hit 3 times...
So far I have tried removing the snapshots on the replicated VMs (we only have 1 per VM), resetting CBT, and running a backup job on the replicated VM (twice), which indicated that CBT was working. However, after running the replication again, and subsequently the backup job - CBT is again not working
I have read this should work, particularly given that Veeam v6 (and presumably v7) replicate the VMs differently to previous versions of Veeam. I have also read that there can be issues with CBT on powered off VMs. Can anyone shed some light on this situation?
