Veeam Backup for Microsoft Office 365 Support for Microsoft Office 365 Multi-Geo Tenant

This article explains how Veeam Backup for Microsoft Office 365 supports backups of Veeam Backup for Microsoft Office 365 tenants with the Multi-Geo feature enabled.

• Exchange Online
  Veeam Backup for Microsoft Office 365 fully supports Exchange Online mailbox backups for Multi-Geo configured tenants.
• SharePoint Online / OneDrive for Business 
  
  • Backup is not supported for any non-personal Multi-Geo SharePoint Online sites.
  • For Multi-Geo SharePoint Online Personal sites and OneDrive for Business, backup is supported with the following limitations:
    • Personal sites must be selected for processing as User objects. For more information, see the Veeam Backup for Microsoft Office 365 User Guide, section Back Up Following Objects.
    • After data migration, a full backup will be performed for the site on the next backup job run. This limitation is caused by an inability to get the required information on site changes after its migration to a different region. At the same time, backup consistency is preserved without any data duplication.
