Veeam Backup for Microsoft 365

What is Veeam Backup for Microsoft 365?

Microsoft keeps the service running; keeping your data is a different job, and it stays yours. That distinction is the whole reason this category of IT infrastructure product exists — and it becomes concrete the first time somebody needs a mailbox deleted eight months ago.

Veeam Backup for Microsoft 365 is a solution for backing up Microsoft 365 data - Exchange Online, SharePoint Online, OneDrive for Business, and Microsoft Teams. Full control over data in Microsoft cloud.

What it protects:

• Exchange Online - mailboxes, folders, attachments
• SharePoint Online - sites, libraries, lists
• OneDrive for Business - user files
• Microsoft Teams - channels, chats, files

Shared Responsibility Model - Microsoft DOESN’T protect:

• Accidental data deletion by user
• Ransomware encrypted in OneDrive/SharePoint
• Departing employee data (after 30 days = loss)
• Long-term retention for compliance

FAQ

Doesn’t Microsoft backup M365? Microsoft provides geo-redundancy and basic retention (30 days). But doesn’t protect against accidental deletion, ransomware, or long-term compliance requirements.

How much does a license cost? Per-user licensing. Price depends on number of M365 users to protect.

Where can I store backups? On-premises (disk, NAS), object storage (S3, Azure Blob, GCS), or combination. Recommended: object storage for lower costs.

How quickly can I restore data? Granular restore - single email or file in minutes. Full mailbox - depends on size, but significantly faster than Microsoft support ticket.

Does nFlo deploy Veeam Backup for M365? Yes. We design architecture, deploy, configure backup policies and retention. Integration with existing Veeam repository or dedicated storage.
