Just want to sanity check this configuration/infrastructure before real testing.
HQ and DR site. Both sites running VMWare ESXi and Veeam Server both ends. IPSEC VPN between the two.
192.168.60.0/24 - Management Network
192.168.61.0/24 - Server Network
192.168.66.0/24 - PC Network
192.168.32.0/24 - All
At the DR site we have a BDC, File Server (DFS) and Exchange Server (DAG).
Backups are performed daily with Veeam (Reverse Incremental) and backups will be replicated/seeded to DR site.
I have to think of all possible failure scenarios to ensure we have a backup solution.
The biggest one I want to tackle first is catastrophic HQ site failure.
In this instance we can seize FSMO roles on the BDC, change the relevant DNS records for Mail, and they can remote access into a few DR PC's to access files (DFS)
They have a BES Express Server and a SQL Server which we will have a Veeam Backup of at the DR site.
My question is if the downtime is extended and they want Blackberries working, can I just bring up the Veeam Backup of the BES Xpress Server, change the LAN IP and it will work?
Same with the SQL Server?
What other complications do I need to think about?
