Disaster Recovery for SCCM

Question

Hi,

Hope everyone well and good.

This is the DR requirement that we have got from one of the US location. This is to test disaster recovery module for USA SCCM.

Let me explain about our infrastructure. We have 1 CAS and 2 Primary site servers. The one is in UK and another one in US.

In US, we have 3 datacentres Pod A and Pod B in one same location and Pod C in different location.

Our SCCM site server is backed up by Veeam back up tool. And we have SCCM DB in dedicated SQL server which is in cluster

So here is my question, so what are the consideration do I need to check with Server team, Network team and DB team for restore the SCCM services in POD C ?

Assuming if I have restored DB and Network Vlan & IP address are moved to the Pod C datacentre.

Would restore work for SCCM site server which we have taken using Veeam backup will work in POD C datacentre?

Here is our DR approach

Shutting down SCCM primary site server and other site systems in POD A/B in US, bringing up the primary site server with same name and IP in POD C using Veeam back up, restoring DB back up to a same version SQL DB server in POD C , installing a SUP in POD C and testing SCCM services from POD C.

Any ideas or suggestion that how to achieve this DR scenario. Am not find any information for this. Share any useful links to check that how to perform disaster recovery module

Answer 1

First off, since you have a cas, and therefore over 150,000 devices, you should contact your tam for support on this question.

Next using veeam Vm backup/restore is not supported, per se. Only a clean vm, with cm installed, restored will be supported.

Don't forget about the clients, you will need to clean up the mess that you will create with out of sync hw inv, sw, inv. Su state messages, etc. Depending on how old your backup is this could take weeks, yes weeks to clean.

I always commend, opening a support case with ms when you are doing a restore as you MIGHT need to edit the db, although since you have a cas you could sync from it.

Answer 2

Thanks for your suggestion Garth.

Allen, We are using SCCM CB 2103 version in our infra. It has 1 CAS and 2 Primary site servers. So management looking for DR solution for one of our primary site server based on US location.

Would it be possible to implement SCCM High availability features for one of our Primary site server under CAS infrastructure. Like Active/Passive node that SCCM site DB hosted with SQL AOAG

If that possible, will propose for SCCM HA for DR scenario

Answer 3

i tried to host the CAS on SQL AOAG after we moved it the SQL replication stopped between the primay and CAS

note: the primary Database hosted on SQL cluster with shared storage

anyone can support me ?
