Automatic Update

By default, Veeam Backup for Microsoft 365 automatically checks Veeam servers for critical updates once a day. If a new critical update is available, Veeam Backup for Microsoft 365 downloads this update in the background and installs it to the following backup infrastructure components:

Veeam Backup for Microsoft 365 server to update Veeam Backup for Microsoft 365, Veeam Explorers, PowerShell, and REST API.
Backup proxy servers.

Important

Automatic update is not supported for the Veeam Backup for Microsoft 365 REST API component installed on a separate machine and Veeam Explorers installed on a server with Veeam Backup & Replication for tenants.

At first, the downloaded updates are installed to the Veeam Backup for Microsoft 365 server within the update window that is a period of the Veeam Backup for Microsoft 365 server idleness. The following conditions must be met:

Restore sessions are not running on the Veeam Backup for Microsoft 365 server.
The Veeam Backup for Microsoft 365 console and PowerShell console are closed. Otherwise, you will be prompted to close these consoles.
Backup, backup copy and retrieval jobs as well as data management jobs are not running on the local backup proxy.

Veeam Explores as well as remote Veeam Backup for Microsoft 365 Console and PowerShell components will be updated only after the Veeam Backup for Microsoft 365 server update completes.

Installation of the downloaded updates to remote backup proxy servers in the Veeam Backup for Microsoft 365 backup infrastructure is performed within the separate update window. Veeam Backup for Microsoft 365 determines a time period when backup, backup copy and retrieval jobs as well as data management jobs are not running on a backup proxy server.

Note

Update windows for the Veeam Backup for Microsoft 365 server (including the local backup proxy) and remote proxy servers can be different.

Thus, automatic update of Veeam Backup for Microsoft 365 can only be performed when the load on the backup infrastructure components is minimal. If Veeam Backup for Microsoft 365 cannot determine the proper update window during a considerable period of time, you will be prompted to install updates manually. For more information, see Checking for Updates.

You can disable automatic update. To do this, clear the Allow for automatic updates check box on the Updates tab. For more information, see New Versions and Automatic Updates.
