What is Veeam Backup for Microsoft 365?
Veeam Backup for Microsoft 365 is the self-managed backup software Veeam Software for Microsoft 365 data — Exchange Online, SharePoint Online, OneDrive for Business and Microsoft Teams — installed on the company's own infrastructure, which decides where the copies are kept. The architecture has a control server on Windows Server, backup proxies talking to the Microsoft Graph API, a configuration database on PostgreSQL and a NATS server for component communication; data goes to a local repository, an SMB share or object storage such as Amazon S3, Azure Blob Storage, IBM Cloud Object Storage and Wasabi. It is the self-managed alternative to Veeam Data Cloud for Microsoft 365, where Veeam runs the service and the storage. Veeam Backup for Microsoft 365 solves the fact that the Microsoft 365 recycle bin and retention policies are not backup: permanent deletion, a disabled account, ransomware on synced files and a misconfigured retention policy leave no way back — and release 8.5 restores item by item, with search, without depending on the tenant.
Key features
Veeam Backup for Microsoft 365 covers backup, secondary copy, immutability and granular recovery in the same console.
- Full tenant coverage — Exchange Online and on-premises Exchange mailboxes, SharePoint sites, OneDrive for Business accounts, Teams with private and shared channels, and channel posts.
- Veeam Explorers — four recovery consoles (Exchange, SharePoint, OneDrive and Teams) to restore an item, folder, site or whole mailbox to the original or an alternate location.
- eDiscovery with advanced search — finds items by sender, period, attachment and content, and exports the result as a .PST file through Microsoft Outlook, to answer a legal request or an audit.
- Immutable repositories — object lock on object storage blocks deletion within the configured period; Veeam automatically adds 10 days on backup repositories and 30 days on backup copy repositories to reduce I/O operations.
- Backup copy — a second copy on different object storage, also immutable, for the 3-2-1 rule without depending on a single provider.
- Backup proxy pools — spread processing across several proxies, which raises throughput and reduces the effect of Microsoft Graph API throttling.
- Restore Portal — a web portal where the end user or a delegated restore operator recovers what they need, without raising a ticket with the infrastructure team.
- REST API and PowerShell — automation of jobs, reports and restores, with MFA and RBAC in the console to separate administrators restore-only staff.
Benefits
Control over where data lands is real because the repository is the company's choice and can be changed later: the same backup can move off an SMB share to Amazon S3 or Azure Blob Storage with no exit penalty. The loss window shrinks because jobs can run every five minutes, and different objects can follow different schedules.
Ransomware resistance comes object lock: within the immutability period, not even a compromised administrative credential s the copy. Support load drops because the Restore Portal hands item recovery to the end user, with scope limited by role. And cloud cost stays predictable because the local cache holds the backup structure, letting you browse in a Veeam Explorer without pulling data object storage.
Who it is for
Veeam Backup for Microsoft 365 serves Microsoft 365 and Exchange administrators, infrastructure teams, and compliance and legal groups that must answer eDiscovery requests. Three scenarios: the company that must keep backup data in its own country or with a specific provider for regulatory reasons; the organization hit by mass deletion that must rebuild mailboxes and sites; and the team running a hybrid organization, with on-premises Exchange and SharePoint alongside the cloud tenant.
What sets it apart
Veeam Backup for Microsoft 365 does not tie the customer to one storage: it takes local JET repositories, SMB shares and object storage several providers, including generic S3-compatible, and lets you migrate between them. Because it is self-managed, backup data never leaves the perimeter the company defined — decisive for data sovereignty and Brazilian LGPD. And the product talks to the rest of the portfolio: monitoring through Veeam ONE, multi-tenant management through Veeam Service Provider Console and protection of the backup server itself through Veeam Backup & Replication.
System requirements
The server runs on Windows Server, with Microsoft .NET Runtime, ASP.NET Core Runtime and .NET Desktop Runtime 8.0 and Windows PowerShell 7.4.2 or later. The configuration database uses PostgreSQL — setup deploys PostgreSQL 16.14 locally when no instance is prepared — plus a NATS server on version 2.10 or 2.12; Veeam recommends hosting both on Linux. Backup proxies run on Windows or Linux. Exporting Exchange items as .PST files requires 64-bit Microsoft Outlook on the machine running Veeam Explorer for Microsoft Exchange. Supported targets include Amazon S3, Azure Blob Storage, IBM Cloud Object Storage, Wasabi and S3-compatible object storage. On the Microsoft side, a Microsoft Entra ID application must be registered; to protect public folder and discovery search mailboxes, that application needs the Exchange.ManageAsApp permission and the Global Reader role.
Editions and license types
The product has one commercial edition and one free edition. The subscription license is the commercial one, with a one to five year term and full functionality. Community Edition is free, never expires and holds back no features, but is capped at 10 user accounts, 1 TB of SharePoint data and 10 Teams — it suits a proof of concept. There are also the evaluation license, the NFR license for demonstration and training, and the rental license, distributed only to service providers.
How much does Veeam Backup for Microsoft 365 cost?
Veeam Backup for Microsoft 365 is licensed per protected user account, as a one to five year subscription. Each protected user consumes one license unit, and that unit covers the same person's Exchange mailbox, OneDrive for Business account and SharePoint personal site — a personal mailbox and an Online Archive together count as one. Restores consume no license. If an object goes 31 days without a backup, its unit is revoked automatically and returns to the pool.
The counting rules that most change a quote: Teams objects, group sites and non-personal SharePoint sites do not consume units; shared, resource, group and public folder mailboxes do not either, as long as they have no Microsoft 365 license assigned; and external SharePoint users and Teams guests stay out of the count. The trap is on the other side: every user who is a member of a protected team or has access to a protected non-personal site must be licensed. There is no single list value because the investment depends on the number of licensable users, the contract term and whether it is a new purchase or a renewal.
