Veeam backup causing IRIS node to be dropped from mirror

Question

Is anyone using Veeam as their external backup product?

I'm trying to backup a Linux VMs (VMWare; SUSE).

These VMs have a mirrored pair IRIS DB.

I'm using the InterSystems's provides pre-freeze - Backup.General(ExternalFreeze)
I'm using the InterSystems's provides post-thaw - Backup.General(ExternalThaw)

I've been running the backups with Veeam 'application aware processing' so I can add the pre-freeze and post-thaw scripts.

I'm backing up the PRIMARY node of the mirror pair.

The problem is that the time take by Veeam between the run of the pre-freeze script and post-thaw script is about 14-16 minutes.

The Veeam processing between the call of pre-freeze script and call of the post-thaw script should only be to create a VMWare snapshot.

On checking the logs I can see that Veeam tries to install the Postgres agent and Oracle agent and both these agents do a discovery
looking for installations of Oracle and Postgres. There does not seem to be anywhere I can turn off the Postgres agent and Oracle agent.

Has anyone had a similar problem?

How did you fix it?

Hi,

not sure about Veeam installing stuff etc.

But i know some customers only backup the backup mirror, never the primary mirror as even with snapshot taking only a couple of seconds, QoS detection get triggered due to a slight performance degradation during the backup. If the backup is running against the Primary mirror, this then results in a forced failover being triggered.
