Restow vs Veeam for Microsoft 365 backup
Veeam sells two different Microsoft 365 products: Veeam Backup for Microsoft 365, which you run on your own Windows server, and Veeam Data Cloud, which Veeam hosts for you. Both are billed per user for as long as you use them.
The short answer
Choose Veeam if you need SharePoint and Teams backed up today, want a vendor-run service with 24/7 support, or already run Veeam elsewhere. Veeam Data Cloud starts at $2.63 per user and month and includes storage.
Choose Restow if you mainly protect Exchange mail and OneDrive, want to pay once instead of per user, and want the backups on storage you control, with a weekly restore test that proves they can be read back.

Where Veeam is strong
- Full Microsoft 365 coverage, including SharePoint and Teams.
- Veeam Data Cloud is fully managed, with storage and 24/7 support in the price.
- Bring-your-own-key encryption through your own Azure Key Vault.
- A free Community Edition for up to 10 users.
- A large partner network and many admins who already know the product.
Where Restow is different
- One payment instead of a monthly fee per user: Business costs €595 once, no matter whether you protect 10 or 1,000 mailboxes.
- No Windows server and no separate database to patch: Restow runs as one Linux container stack.
- Your storage, your region, including plain local disks or NFS.
- Every week Restow restores a sample from each backup and compares it byte for byte. A backup that has not been checked is shown as not proven.
- Open source core and an open storage format, so leaving Restow does not mean losing access to your backups.
5-year cost at three sizes
Restow at list price from release, plus server, storage and admin time, against Veeam Data Cloud (Foundation) at its published list price. Net, in euros.
25 mailboxes
Veeam Data Cloud (Foundation) is €1,500 cheaper
150 mailboxes
Restow is €13,796 cheaper
MSP, 20 tenants, 1,000 mailboxes
Restow is €149,503 cheaper
Veeam Data Cloud includes storage, 24/7 support, SharePoint and Teams; Restow does not cover SharePoint and Teams. Not like for like. In the MSP case each tenant is priced at Veeam's end-customer list price; partner prices are not public and are likely lower. Every assumption and source · calculator with your numbers
What Veeam costs over five years
Veeam publishes list prices only for Veeam Data Cloud. At the Foundation rate, 150 users cost $3.15 per user and month, which is about $28,350 over five years before tax, storage included. The self-hosted Veeam Backup for Microsoft 365 is priced per user through resellers, and you add the Windows server, its license, the database and the storage yourself.
For Restow the license is a one-time €595 (Business), and you pay for the server, storage and the time you spend running it. Our 5-year cost chart puts both side by side with every assumption listed. At very small sizes a per-user service can be cheaper; the gap turns in Restow's favour as the number of mailboxes grows.
What Restow does not do (yet)
- Restow does not back up SharePoint or Teams in version 1.
- The audit log, SSO and roles are in development for Business.
- Licenses include no support; setup is available on quote.
- The server and endpoint agent runs on Linux and macOS, file-level; Windows is planned.
- Restow 0.1.0 is a beta: do not use it as your only backup.
Veeam: the facts, with sources
Each line is taken from Veeam's own documentation unless the rating says otherwise. "Checked: not found" means we looked in the named sources and did not find it, which is not proof that it does not exist.
| Fact | Source | How solid |
|---|---|---|
| VBM365's self-hosted server component requires 64-bit Windows Server (2016–2025) or Windows 10/11; backup proxies run on Windows, or on Linux only for object-storage repositories; a local, remote or Azure-hosted PostgreSQL 15.9+/16.4+ database is required. | Veeam system requirements | Official source |
| Licensed per protected user, sold as a subscription or, for service providers, a monthly rental. No perpetual license is documented in official sources. | Licensing and License Types, Rental License | Official source |
| A free Community Edition exists, unlimited in time: up to 10 user accounts, 1 TB of SharePoint data, 10 Teams; restoring does not need a license at all. | Licensing and License Types | Official source |
| After a license lapses: a one-month grace period for subscriptions, two months for rental licenses; after that, backup jobs stop but restoring already-backed-up data stays possible. | Subscription License | Official source |
| Veeam Data Cloud for Microsoft 365 publishes list prices, billed annually, backup storage and 24x7 support included: Foundation $3.50 (10 to 50 users), $3.15 (51 to 250) and $2.63 (251+) per user per month; Advanced $3.71 per user per month ($3.33 with volume discount); Premium $7.00. Prices may vary by region. | Veeam Data Cloud pricing and purchasing options (read 2026-09-29) | Official source |
| Veeam Data Cloud (the SaaS product) is billed per user (covering their mailbox, OneDrive and personal site) on annual, multi-year or monthly terms. If a protected object has no restore point for 31 days, its individual license is released and stops counting toward the total licensed count (freeing it up, rather than a penalty). | Veeam Data Cloud licensing | Official source |
| Veeam Data Cloud stores data in dedicated, Veeam-operated Azure storage accounts in a region you pick, including Germany West Central and the EU Data Boundary; the Express plan instead uses Microsoft 365 Backup Storage. No option to use your own storage was found. | Region availability | Official source |
| Encryption keys for Veeam Data Cloud are bring-your-own via the customer's own Azure Key Vault. Veeam does not hold the key material itself. | BYOK encryption | Official source |
| No automated, SureBackup-style test-restore feature for Microsoft 365 backups was found in the 8.6 release documentation; a Veeam product manager stated on the community forum (26 September 2023) that no such feature existed at that time. | Veeam community forum | Moderate |
| PST export is available through Veeam Explorer, but requires a local Microsoft Outlook installation to run. | One-click export | Official source |
| No open-source edition or AGPL/GPL licensing was found for either product; both are proprietary commercial software. | Absence checked across the licensing pages above | Checked: not found |

Does Veeam Backup for Microsoft 365 need Windows?
Yes. The server component requires 64-bit Windows Server 2016 to 2025 or Windows 10/11, plus a PostgreSQL database. Restow runs on Linux in Docker.
Can I keep my backups when I stop paying?
With VBM365, backup jobs stop after a grace period but restores stay possible. With Restow there is nothing that expires: the license is permanent, and the storage format is open, so a standalone tool can restore without a running Restow server.
