Hello, we are reviewing our current DR setup and would like to expand on our current Veeam jobs.
Datacentre: 2 ESXi 5.5 host's running 14 VM's. Roles include - 2 DC's, Exchange 2010 (standaole, no DAG), ShoreTel HQ Sevrer, File Servers, App servers, Veeam B&R and Proxy (same VM).
Offsite: Direct attached (same subnet) via fibre (500m down road). 2 ESXi 5.5 host's, 1 set as Veeam Repo Server. 1 Unused.
Veeam Config: Backup jobs only for all 14 VM's running daily (out of hours) to the backup Repo. at our Offsite. Daily Veeam Configuration backup to same location.
Continue to backup All VM's to current Repo. host but utilise replication (15min intervals) to keep a cold state of our tier 1 VM's (Exchange, ShoreTel HQ, File) on the spare ESXi host at the offsite.
Archive backup jobs to further device for true offsite backup storage.
Is it still the case that backup's of DC's are fine but replication is a bad idea? I'm assuming so.
In the event of a primary Data Centre failure how would you go about starting the restore process at the Offsite location? my thinking was to:
Build a Veeam B&R instance and restore from the config backups.
Restore and boot the DC's to the Replica target ESXi hosts
Start bringing up the replica's.
Would this work?
Thanks and sorry for the simple nature of my post, just want to make sure I have the basics down.
