Veeam Backup Enterprise Manager limitation

[Nas]

Hi

Is there a limitation on the number of Veeam Backup Servers that we can add to Veeam Backup Enterprise Manager?
I have a single Veeam Backup Enterprise Manager with 50 Backup Servers (from 3 different region) added to it.

My daily Data Collection Job Sessions is taking more than 24 hours to complete, so I'm wondering if I have hit the limit and whether I should separate these Backup Servers to multiple instances of Veeam Backup Enterprise Manager.

Thanks.

Hello Nas

50 backup server shouldn't be an issue. We have some customers with several 100 backup server managed by a single Enterprise Manager.
May I ask, how many Workloads (VMs, Agents) are managed by those backup servers?

Best,
Fabian

Hi Fabian,

Total workloads is 1950.

VM 1880
Agent 60
File shares 10

Thanks.

Hi Nas

Thanks.
I assume, the cause of the long data collection must be with the hardware resources available to the enterprise manager server or the database server.
Make sure to size your enterprise manager server according to our recommendation (8 cores, 16GB RAM + OS requirements). You need more cores/memory if you run other workload on the same server (backup server, other applications, database engine): https://bp.veeam.com/vbr/2_Design_Struc ... er-compute

Additionally I recommend to open a support case. Logs will show us why the data collection takes 24 hours and where we can optimize the processing time.

Best,

In my experience this is because Enterprise Manager collects the data from a single VBR at a time, it is all serialized.

The collection of the VBR in the same data center with 300+ protected workloads completes in 8 seconds.
The collection of a VBR 168ms away with 2 protected workloads takes over 2 1/2 minutes.

This has nothing to do with available resources but all with the design of the Enterprise Manager.
