Veeam Backup for Microsoft 365 extends data protection and follows the same methodology as Veeam Backup and Replication. This 3-2-1-1-0 rule can also be applied to backup repositories in cloud-based object storage using Backup Copy Jobs: Azure Blob Storage Archive access tier, Amazon S3 Glacier storage class, or Amazon S3 Glacier Deep Archive storage class.
You can create different tiers of backup jobs when creating backup jobs. For example, a gold backup tier for executives has a higher retention rate. On the other hand, a silver backup tier for seasonal teammates necessitates a different retention period and settings. This could be divided into different departments to share costs across storage accounts.
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.
If you try to add an organization with modern authentication and legacy protocols or basic authentication at Veeam Backup for Microsoft 365 but failed, the error message is ” Connect to PowerShell: Connecting to remote server outlook.office365.com failed with the following error message: Access is denied”.
If you try to add organization at Veeam Backup for Microsoft 365, it happens Connect to PowerShell: Connecting to remote server outlook.office365.com failed with the following error message: Access is denied error, that’s because Microsoft begin disabling Basic authentication for Outlook, EWS, RPS, POP, IMAP, and EAS protocols in Exchange Online.
You are required to provide a username and password to authenticate to your Microsoft 365 organization if you add an organization using the basic authentication method.
I won’t recommend adding organization with basic authentication, Microsoft announced that effective October 1, 2022, we will begin disabling Basic authentication for Outlook, EWS, RPS, POP, IMAP, and EAS protocols in Exchange Online. SMTP Auth will also be disabled if it is not being used.
You will use both Veeam Backup account and Azure AD application for authentication if you add an organization using the modern authentication method with legacy protocols allowed. Veeam Backup for Microsoft 365 uses Veeam Backup account and an application to establish a connection to your Microsoft 365 organizations with disabled security defaults and maintain data transfer during backup and restore sessions.
