Step 7. Configure Azure Archiver Appliance

At this step of the wizard, you can optionally enable usage of the Azure archiver appliance when Veeam Backup for Microsoft 365 transfers backed-up data between different instances of Azure Blob Storage or to Azure Blob Storage Archive. If you use the Azure archiver appliance, it usually speeds up the backup copy process and helps you reduce costs incurred by your cloud storage provider.

The Azure archiver appliance is a small auxiliary machine in Microsoft Azure that is deployed and configured automatically by Veeam Backup for Microsoft 365. Veeam services that Veeam Backup for Microsoft 365 installs on the Azure archiver appliance compress data passed through. This helps reduce network traffic and increase the speed of backup copy.

The process of the Azure archiver appliance deployment takes a couple of minutes. If you enable usage of the Azure archiver appliance, Veeam Backup for Microsoft 365 will create the archiver appliance at the beginning of a backup copy job and remove or reuse it after a backup copy job completes. By default, Veeam Backup for Microsoft 365 always keeps one archiver appliance for reuse.

If you do not want to use the Azure archiver appliance, skip this step and click Finish.


Even if you have enabled usage of the archiver appliance for object storage, Veeam Backup for Microsoft 365 will not create it when transferring backed-up data between object storage of different vendors.

  1. Select the Use an archiver appliance to copy data to this repository check box.
