best practice

[dirkdigs]

we have production server in 2 physical locations we will be setting up 1 backup repo per site. its a vsphere / iscsi infra.
for replication would it make more sens to have the replicas on the production san or the same backup repo as the daily backups?

Hello Mike,
Do you use backup copy jobs? Have you considered Remote Replica from Backup option?

Depending on what you're protecting from (VM failure, host failure, SAN failure, entire site failure, etc.). E.g. if you want to be able to quickly failover to a ready-to-start replica VM in case of production SAN failure, you need to keep replicas on some other storage (but presumably in the same site). First of all, think about use cases and then best practices will be clear.

not sure what youre using for a backup appliance, but replicas arent going to work anywhere an actual vm cant reside, as replicas are complete vms. we have a stand alone host, with about 10tb of storage offsite we replicate too. in a perfect world, this would also run vcenter and veeam, with a domain controller.

Yeah, for replicas it's recommended to run the relication job from VBR server installed on the DR site, so in a case of production site disaster you can still manage the VM and job.

i am protecting from all the above.

im assuming with this option the RTO will be based on timings of my backup jobs?

example
backup server 1x per day
remote replica will be same 24 hours old.

Correct.
What RPO requirements do you have?
