How to run a Microsoft 365 Backup RFP
What you're really buying is the ability to restore, so agree on what you need to recover, how quickly and from how far back before vendors get involved. The example schedule below runs about 10 weeks from kickoff to contract award; stretch it if you have several tenants or a Multi-Geo tenant, or if your legal hold requirements are still being settled.
- Inventory the tenant and set recovery targets (weeks 1-2). Count what vendors will size and price against: licensed users, shared and resource mailboxes, archive mailboxes, OneDrive accounts, SharePoint sites, teams, and data volume and growth by workload. Set a recovery point objective and recovery time objective for each workload, a retention period for backups, and any legal hold obligations. List the Microsoft 365 retention policies and holds you already use, so the backup design complements them.
- Assemble the buying team. Include the Exchange, SharePoint and Teams administrators, the identity team that owns Entra ID, security operations, whoever runs backup today, and legal, records management, privacy and procurement. Bring security in early: a backup product needs tenant-wide permissions to read and restore your data, and it holds a full copy of it.
- Decide whether you need an RFI (weeks 2-3). If you haven't decided between Microsoft's native options, a vendor-hosted backup service and software you run yourself, or your long list has more than five vendors, send a short RFI first. Ask which workloads each product covers, where backup data is stored, how pricing is counted and which regions are supported. Use the answers to build a shortlist of three or four.
- Tailor and issue the RFP (weeks 3-6). Delete requirements that don't apply, adjust priorities, and add your tenant numbers to Section 1. Make Entra ID backup, Multi-Geo support and cross-tenant restore Must-haves if you depend on them. Give vendors three weeks to respond, with a written question-and-answer window in the first week.
- Score the responses (weeks 6-7). Have each evaluator score independently against the rubric before comparing notes, and set aside any vendor that misses a Must-have. For each workload, check exactly which item types are covered, and whether every 'yes' is generally available today or still on the roadmap.
- Run a proof of concept with two vendors (weeks 7-9). Use a test tenant or a pilot group, after security has reviewed the permissions each product requests. Time the first backup of a sample, then test the restores you'd need in a real incident: a single email, a full mailbox, a SharePoint site to a new location, a Teams channel, a simulated mass deletion and, if relevant, a restore into another tenant. Check that permissions, metadata and versions come back intact and that every action appears in the audit log.
- Negotiate and award (weeks 9-10). Use the pricing table to compare like for like. Settle how shared mailboxes and departed users are counted, storage limits, renewal caps and exit terms, including how you'd get your backup data out, before you sign.
Microsoft 365 Backup RFP requirements
Each line is written to paste straight into your RFP. Must-have means a vendor that cannot meet it is out; Nice-to-have earns extra points. Change the priorities to fit your situation, and delete what doesn't apply.

Nice-to-have |
Technical and architecture
| ID |
Requirement |
Priority |
| T1 |
Backup copies held outside our Microsoft 365 tenant, in a separate storage location and security domain, so that a compromised Microsoft 365 administrator account cannot delete or alter them. State where each copy is stored, and whether it can be kept in a cloud storage account we own. |
Must-have |
| T2 |
Immutable backup storage: retention locks that no single administrator, ours or the vendor's, can shorten or remove before the retention period ends. |

Must-have |
| T4 |
Choice of the region where backup data, search indexes and metadata are stored, to meet our data-residency requirements. |
Must-have |
| T5 |
Support for Microsoft 365 Multi-Geo: back up and restore users and sites in every geography of our tenant, and keep each backup in the region we specify. Make this Must-have if your tenant uses Multi-Geo. |

Questions to ask Microsoft 365 Backup vendors
These questions are designed to separate vendors, not to collect brochure answers. Ask for evidence: a demo, a document or a reference.
- For each workload, list the item types, metadata and permissions you capture and the ones you don't. Where is this documented, and how do you tell customers when it changes?
- Which Microsoft APIs do you use to back up and restore Exchange Online mailboxes, including archive mailboxes and Microsoft 365 Group mailboxes, as Microsoft phases out Exchange Web Services? Which gaps remain, and what is your plan and date for each?
- How do you handle Microsoft 365 API throttling in a tenant of our size? What happens to backup frequency when you're throttled, and how would we see the recovery point you actually achieved?
- Where is each copy of our backup data stored: in storage you operate, in a cloud account we own, inside Microsoft 365 (for example, Microsoft 365 Backup Storage), or a combination? Which restore scenarios use which copy?
- An attacker has taken over one of our Global Administrator accounts and a backup administrator account. Walk us through what they could and could not do to our backups, and what would alert us.
- Demonstrate restoring a single Teams channel message, a private channel and a 1:1 chat. What goes back into Teams, and what is only available as an export?
- Demonstrate restoring a SharePoint site to a new location. Which permissions, metadata, versions and customizations come back, and which don't?
- Which Entra ID objects and settings do you back up? Show the restore of a deleted Conditional Access policy and an app registration. If an object was permanently deleted, what is re-created and what is lost, such as object IDs, credentials or assignments?
- Ransomware has encrypted files in [number] OneDrive accounts over two days. How does your product identify the affected files and the last clean restore point, how long would the restore take, and what is that estimate based on?
- How do you restore data from one Microsoft 365 tenant into another, including mapping users and sites and resolving conflicts? Which items don't transfer?
- How do you support Multi-Geo tenants and data residency for backup data, search indexes, metadata and support access?
- Which features in your proposal are generally available today, and which are in preview or on the roadmap? Give dates for the roadmap items.
- When Microsoft has added a workload or changed an API in the last two years, how long did it take you to support the change? Give examples with dates.
- If we leave, how do we get our backup data out, in what formats, how long would it take for our data volume, and what would it cost?
- Provide a reference customer of similar size that has completed a large restore with your product, such as a full site or bulk mailbox recovery.

Frequently asked questions
What should a Microsoft 365 backup RFP include?
Your tenant numbers and recovery targets; requirements for each workload (Exchange Online, OneDrive, SharePoint Online, Teams and, if you need it, Entra ID) marked Must-have or Nice-to-have; restore options; immutability and where backup data is stored; retention, legal hold and search; security and compliance terms; support and SLA terms; a pricing table that defines who is billable; and the rubric you'll score with. This template includes all of them.
Do you need Microsoft 365 backup if you already use retention policies?
Microsoft describes its Purview retention policies as a compliance feature: they keep content in place, in the same tenant, so it can't be permanently deleted before the retention period ends and stays available for eDiscovery. A backup keeps separate copies you can restore to a chosen point in time after deletion, corruption or ransomware. Decide which restores, retention periods and storage separation you need, then check whether your current setup provides them.
Does Microsoft offer its own Microsoft 365 backup?
Yes. Microsoft 365 Backup is a separately billed, pay-as-you-go service that backs up SharePoint sites, OneDrive accounts and Exchange Online mailboxes, and Microsoft states that its backups stay within the Microsoft 365 data boundary. Microsoft also offers Microsoft Entra Backup and Recovery for directory objects. Check the current scope, retention limits and pricing in Microsoft's documentation, and score these options against the same requirements as any other proposal.
How long does a Microsoft 365 backup RFP take?
The example schedule in this template runs about 10 weeks from kickoff to contract award, including three weeks for vendor responses and about three weeks for a proof of concept. Allow more time if you have several tenants or a Multi-Geo tenant, if the first full backup of a large tenant must finish during the proof of concept, or if security review of a backup product's permissions is new to your organization.
What should you test in a Microsoft 365 backup proof of concept?
Test restores, not just backups: a single email, a full mailbox, a OneDrive account, a SharePoint site restored to a new location, a Teams channel and a simulated mass deletion. Check that permissions, metadata and version history come back intact, time each restore, and confirm that every action appears in the audit log. If cross-tenant restore or Entra ID recovery is a Must-have for you, test those too.
