[Object Storage] - Connection Mode

[CarlosEsteves]

Hello all,

I was looking in the documentation - https://helpcenter.veeam.com/docs/vbr/u ... tml?ver=13 and I did not see any explanation on how multiple gateway selection works?

If I have a Azure Storage Account added as repository and select to use 2 gateways in the connection mode, how does Veeam will select each gateway to use during backup and restore operations ?

Hi Carlos,

Please see the Gateway Selection section of the Gateway user guide page. It explains the selection process.

Gateway Selection

Whenever possible, Veeam Backup & Replication distributes the backup workload between multiple available gateway servers. This helps optimize performance of multiple concurrent tasks. Veeam Backup & Replication assigns a separate gateway server for each task, based on gateway server connectivity and their current load. When Veeam Backup & Replication selects gateway servers, the following applies:

If the number of tasks is greater than the number of available gateway servers, Veeam Backup & Replication uses one gateway server for multiple tasks.
Veeam Backup & Replication uses one gateway server for the whole job if the Use per-machine backup files option is disabled for the repository to which the job is targeted at. For more information on this option, see Backup Chain Formats.
For per-machine VM backups, Veeam Backup & Replication uses one gateway server to process all disks of a VM.
You can select gateway servers explicitly or instruct Veeam Backup & Replication to select them automatically. For more information on which backup infrastructure components Veeam Backup & Replication uses as gateway servers during automatic selection, see the Automatic Selection section.


Sorry, not clear to me.

How Veeam determine which gateway to be used from the list ? What are the checks before use a gateway ?
