memory spike every 15 min - Configuration Database Resynchronize

I am pretty sure there is no readily available setting to change in the UI.  This would be more of a registry thing and contacting Support is the path I would advise.  I am sure they have a way to change this setting to be less frequent.

Hi @Nikks -

This resync is actually an automated Veeam Repository Rescan. I forgot about that, and when researching this issue for you, found it on the below Forums post:

https://forums.veeam.com/vmware-vsphere-f24/configuration-database-resynchronize-t28396.html

I didn’t find much info on this Veeam task (i.e. why it runs at a given time, why needed so often, why it runs during Jobs, etc), so as Chris shared, probably best to get with Support for more details, and if there’s a registry change which can be made to make this less frequent if you’re running out of system resources.

Sure... No problem. Glad to help. 

@Nikks

a simple question for you…. is your database (MSSQL or Postgres) optimized for memory usage? 

My question starts from your first words

I’m noticing that memory usage spikes to 95% every 15 minutes before dropping back down

I don’t know your configurations but normally this means your VBR server is not optimized for memory usage in database. 

as a best practice: 

SQL Server normally can be set from 50 to 75% of installed RAM 

Postgresql normally can be set from 25 to 50% of installed RAM

These configurations prevent the server from performance bottlenecks.
 

You can use the DB Configuration utility to check what you are using for each product - https://helpcenter.veeam.com/docs/backup/vsphere/using_dbconfig_utility.html?ver=120

@Chris.Childerhose / @Andanet - wasn’t there a ‘best practice DB config’ post on here, or a KB Veeam shared “recently”, like 2-3mos ago on the need to do this….maybe especially after major changes? Like, after an upgrade, or some Proxy/Repo type change? Gosh, I can’t remember that far back… 😂

There is this one for Postgres - https://helpcenter.veeam.com/docs/backup/vsphere/postgresql_instance_configuration.html?ver=120

For SQL there is many online resources as those are common regardless of applications.

@Chris.Childerhose - yeah...mabye that was it. Looks like it. Thanks! 😊

Any time.  Always keep these things handy now that I am planning PG migration for all services VBR/VCC.  😎
