we recently start to use Veeam B&R for the backups of our datacenter.
For the backups everything is OK, but we are experiencing some poor performance during a replication job. I try to explain :
The job starts and build the VM list regularly but instead of starting processing the VMs, it wait some minutes for every VM before start transfer data. Once the data transfer is started then is very fast. Here an example for our Exchange VM :
Code: Select all

Let me know if you need other details.
Thanks in advance.
