You can also upgrade to Veeam 7 with the new patch installed:

Added ability for application-aware processing logic to detect passive Microsoft Exchange DAG database present on the VM, and process it accordingly.
Added support for Exchange CCR clusters.

The complete list of improvements you can find here and also here you can download the Patch itself:

We have 1 site with 2 DAG members. Now if the one of them crush how can I restore full server and make sync after restoring. Does Veeam know like in (AD restore) to keep sync alive after recovery or we need to make addiotional steps to amke everything work?

We are performing image backup

We still have the Databases failover to the secondary DAG partner every night during the VMware snapshot consolidation process and we are using fast storage and direct SAN backup. Anyone hit this issue with all of the recommended changes like we are?

[MERGED] Exchange 2010/2013 backup question

Veeam LogoPosted: Tue Sep 22, 2015 4:52 pm
by hscox030
I am curious how other people are doing their Exchange 2010/2013 Veeam backups. I have tried Veeam suggestions related to snapshots (except for the vmx file change) but still have issues with a database failover during the snapshot creation. I have decided to backup my passive nodes but my problem is if I do a snapshot, backup my databases then integrate the snapshots I can not get my snapshot files integrated if I keep the database copies running. The DB Copies are writing so much data to the snapshot files that I cannot integrate the snapshots fast enough. I end up with a snapshot integration that can never finish. Is anyone else running into a similar issue? Currently I am turning off the DB Copies during the backup process then turning them back on after the job completes. Does anyone having any thoughts/suggestions/etc.?

Thank you for your time.

[MERGED] Exchange 2013 Replication Backup

I need some advise with regards to our new Exchange 2013

we have Exchange 1 (All Exchange Roles) and Exchange 2(All Exchange Roles), its a load balance and replication

now since the two are mirror, do I need to include this two exchange in my Veeam Backup Jobs or only one of them?

What is the best practice for this scenario.

[MERGED] Exchange 2013 DAG Backup with Veeam?

how do you backup DAG with Veeam? I red, that a completly passive DAG Member should be used to backup the Databases. Using this method, no impact on the production should appear.

But how do you drop the transaction logs on the active DAG members?

Thanks for some hints...

Pascal, the thread above and this post are likely to answer your question.

Transaction Log Truncating is replicated through DAG. So if you truncate on the passive Database, it is replicated to the other nodes. This is a core functionality from Exchange DAG (not from Veeam).
Here you can find a lot of informations: ... plication/

Just an additional small comment for all the others.
Lately some of our customers contacted me and said that round about VMware SnapShot commit they face DAG cluster failovers.
When I analysed it, the reason was NFS Datastores are used with HotAdd backup mode. This is ugly in 2 ways:

1) NFS is not supported with Exchange (and there is a technical reason behind that) => see my blog above.
2) HotAdd with NFS can cause some VM stunns at DiskHotAdd release => See my Blog and VMware KB.

=> Change Datastore for Exchange to a block media or if you want to keep it really on NFS, use NBD-Network mode or the new v9 DirectNFS backup mode.

1) Increase the DAG heartbeat time (no reboot needed) to avoid cluster failover
cluster /prop SameSubnetDelay=2000:DWORD
cluster /prop CrossSubnetDelay=4000:DWORD
cluster /prop CrossSubnetThreshold=10:DWORD
cluster /prop SameSubnetThreshold=10:DWORD

I'm looking at moving our Exchange 2010 DAG backups over to Veeam now. Should I apply these cluster timeout settings on both the Active and Passive node?

It is a cluster wide setting. So per DAG Group.
To be save test it with
cluster /prop
on all cluster members. blog post was updated two days ago: ... plication/

[MERGED] Exchange 2013 DAG backup

we are about to implement an Exchange 2013 DAG. our current Backup strategy is to backup the Domain Controller and the Exchange Server with Veeam.
as for DAG members, it is possible to backup both, the active and passive member with Veeam.
in the Event of a disaster i see a lot of Posts to recover a lost DAG member with Exchange Setup recover Switch. i am wondering, if the following case will result in any success:
- Recover both, active and passive node
- DR happens and active node gets lost
- Exchange will continue to operate on the passive node
- Restore lost node with Veeam Backup
- Boot restored node -> what will happen then.

anyone any experience with this Situation. it seems to me like a very common Scenario in a 2 node DAG.
