Performance Issues since update to B&R 12.3.1.1139

[nintehol]

Hi all,

we have performance issues since upgrading to B&R 12.3.1.1139

We start the backup job (8 conncurent VM's) VM's stucking at 0% with 0KB/s for around 10 Minutes after that time backup starts with regular performance comparing to speed prior updateing.
next conncurent VM's during jog stucking again 0% with 0KB/s for around 10 Minutes and so on

B&R 12.3.1.1139 simple deployment on local disks (SSD), W2K22

vCenter 8.0.3.00400

3x hosts @ VMware ESXi, 8.0.3, 24585383

SAN (Datacore SANsymphony 10.0 PSP19) with Fibre Channel SAN 16G

Great Performance befor updating to B&R 12.3.1.1139

Does anyone have comparable problems?

We have raised support ticket as well.

thanks
Holger

Hi nintehol, welcome to the forums.

Sorry to hear about the troubles and thank you for opening a case in advance. May I ask you to share the case number please?

I'm not immediately familiar with any known issues that match the above description, so let's see what Veeam Support sees in the logs.

Out of curiosity, since you have Datacore, are you using the Veeam Datacore plugin to allow Backup from Storage Snapshot as the transport mode or you are using DirectSAN/Hotadd/NBD?

If you are using Backup from Storage Snapshots, can you check some of the VMs and see if they have leftover snapshots? (Check both snapshot manager and on the datastore folders themselves as leftover snapshot delta files may not show in the Snapshot Manager)

I ask on snapshots as they will increase the processing time for Backup from Storage Snapshots.
