Veeam Backup for Microsoft 365 • Stalling Jobs

Hi All,

We are currently experiencing issues with Veeam Backup For Microsoft 365. We are running the latest version of 8.1, the main controller server also runs Postgresql and NATS-SERVER. We have two Proxy Pools consisting of 4 Linux Proxies each. We use one Proxy Pool for onboarding new customers and the other for BAU jobs. We split each tenant into 3 jobs, Exchange, OneDrive and SharePoint/Teams. Each customer also gets 3 Wasabi Buckets (Exchange, OneDrive and SharePoint/Teams) which are used as an individual repo per job (I.E Customer A Exchange Backup targets Customer A Exchange Repo etc). We are seeing a mixture of slow or stalled jobs. The only "fix" we currently have is to stop Veeam Services, rename the streams folder in NATS and restart the controller server. This seems to give VBO a kick to start jobs again, but having to do this all the time is not great. I have enabled monitoring in the NATS config file to allow us with additional monitoring to try and pin point what is causing these issues. But so far, we are unsure what is causing the problems. I have noticed that we are getting API errors, approx 5% of API requests are errors, I am very new to NATS so I am not sure what is causing this. We have a load of available "out the box" monitoring but we also have the ability to configure custom monitors, which I have been doing. Has anyone got any advice on what things we should be specifically monitoring, especially with regards to NATS-SERVER and Postgresql that I can look at adding in. Or has anyone else experienced similar issues? If so, what have you done to resolve this?

**Edit** Monitoring of the controller server seems fine, no spikes in CPU/Memory. Also the resources on our Proxies are good too, averaging around 50% max usage on all proxies.

We have a support request open # 07607359 but we are not getting anywhere very fast at the moment.

Thanks in advance!
Keiron
