VBR13 MSSQL Plugin Backup in Azure

[PospiKM]

Hello,

I would like to discuss or get better overview of community experience with MSSQL Plugin Backups in Microsoft Azure that are maintained from the VBR (version 13) side, not standalone. As I'm new to such concept, I am very curious about some performance topics.

We use Azure Blob storage as a target for MSSQL backups and for now we have several policies (there will be much more in the future), backing up tens of servers (hundreds in the future).

What is the ideal or recommended configuration to get the best performance from the backups? Especially talking about the number of backup stripes/channels/parallel processing (data/logs) versus data reduction?
What is the maximum recommended MSSQL servers/instaces in one backup policy in terms of performance?
What is the recommended number of datamovers/gateways versus number of MSSQL servers/instaces to backed-up at the same time? Is anyone using the gateways or prefer direct backups?

Thank you.
Tom
