Many to One WAN Acceleration

[roscomputers]

Hello all.
For example, we use 3 standalone Veeam Backup & Replication 9.5 on the remote/branch offices.
In the branch office we have tape library.
We must copy backups to the branch office tape library.
Can i use target WAN accelerator service on the branch office backup server for 2 remote office source WAN accelerators?

Hello,
I'm not sure about your setup. Tape jobs cannot use the WAN-Accelerator.

You need to bring everything to one the location with the tape with backup copy jobs. Backup copy jobs can use the WAN accelerator. And the WAN-accelerator supports many-to-one


Best regards,
Hannes

One WAN Accelerator can server the role of target for many source WAN Accelerators. However, as Hannes mentioned, tape job do not leverage WAN Acceleration. Thanks!

[roscomputers]

Thank you!
Yes, tape job do not leverage WAN Acceleration.
As i say, Veeam Backup & Replication 9.5 installed on a every office.

Can i use target WAN-accelerator another Veeam B&R installation? Most probably not.

I plan implement 2 VMs for target WAN-accelerators (remote office 1 and remote office 2) on a branch office.
Create backup repository on target WAN-accelerators.
Create backup copy job on remote office 1 and remote office 2.
Create backup on tape job for VMs on a branch office

well, you can - but that brings you in the situation that you run a WAN accelerator from VBR-X on VBR-Y. That's quite bad design. If possible I would just consolidate everything to one central VBR server that manages all three locations.

Yes, additional VMs for WAN accelerators are also a good way.

For the tape job: You can always use file to tape. But keep in mind that "backup to tape" only works if the backups were created with the backup server which is managing the tape. To avoid that, you could one central VBR server that manages everything.

Ok. Thank's.

Best practice is consolidate everything to one central VBR server.

But if central VBR server will fall, we will not have protection data on a remote offices.

The Veeam documentation does not say anything about this. You say that this is a bad design.
The documentation says:"if you have several remote/branch offices, you can configure several source WAN accelerators in remote sites and one target WAN accelerator in the head office."

Please provide an official response from Veeam.

the user guide does not cover multiple backup servers. see this section

You must add the machine to the Veeam Backup & Replication console as a managed server.

"the backup server " is the important phrase

the user guide does not cover best practices. It only describes what is possible. there is a separate best practice guide - https://www.veeambp.com/ - but this also does not cover your scenario (because it is a ugly design, as I mentioned before)
