Microsoft 365 has recovery and retention features, and separate backup options also exist. Check your actual coverage before assuming everything is protected or buying another product. On this page ## Three different jobs | Feature | The question it helps answer | | --- | --- | | Synchronisation | Are changes available across the places where we work? | | Retention | Which content should be kept or deleted under our policy? | | Backup and recovery | Can we restore the data we need after a loss or unwanted change? | [Microsoft Purview retention](https://learn.microsoft.com/en-us/purview/retention) can preserve or delete content according to configured policies. Its purpose and behaviour need to be understood separately from a business recovery plan. Microsoft also offers [Microsoft 365 Backup](https://learn.microsoft.com/en-us/microsoft-365/backup/backup-overview?view=o365-worldwide) for supported Exchange, OneDrive and SharePoint data. It is a distinct service; its existence does not mean that your organisation has enabled the right policies or protected every workload. ## Start with two realistic scenarios A colleague overwrites an important document. Identify the file, when the problem happened and which recovery options are available. A limited file recovery may be enough. A large amount of business data is damaged or deleted. The challenge includes choosing a clean recovery point, coordinating people and checking restored content. Recovering one test file does not establish how quickly the whole business could recover. These are planning examples, not claims about a particular product’s performance. Write down the business outcome you need before comparing tools. ## Ask your IT provider these questions - Which mailboxes, sites, accounts and other workloads are protected today? - Which important data is outside that protection? - How often are recovery points created, and how long are they kept? - Who is allowed to change protection settings or restore data? - What happens to protection when someone leaves or a licence changes? - What happens if billing, permissions or a backup job fails? - When was the last restore test, and what did it demonstrate? - What costs apply to storage, restoration, support and cancellation? Keep the answers in a short coverage record. “Included in our subscription” should be followed by the product name, scope and relevant settings. ## Test safely before an emergency Our recommended starting exercise is a small, agreed restore using non-sensitive test content. Record the requested recovery point, who performed the restore, the elapsed time and whether the restored content was usable. Use an approved destination and avoid overwriting live work. A larger recovery exercise needs its own plan and permissions. Agree who would make decisions during an incident and where that plan can be found if normal email is unavailable. ## Choose the right next step If your coverage is clear and recent testing meets the business need, document it and review it when the setup changes. If there are gaps, compare Microsoft’s backup service and suitable third-party options against those gaps. Check current product coverage, storage location, access controls and pricing before committing. Our [Microsoft 365 security checklist](https://cloud365.io/blog/microsoft-365-security-checklist/) puts recovery alongside sign-in security, administrator access and sharing. Backup is one part of the overall setup. ## Get an independent view of your setup A [Microsoft 365 security audit](https://cloud365.io/microsoft-365-security-audit/) can identify areas needing closer review and help prioritise next steps. The audit is read-only; it does not include a destructive recovery exercise or automatically install a backup product. Any implementation or restore testing is scoped separately. [Ask about a Microsoft 365 review](https://cloud365.io/start/?service=audit), or [read the illustrative sample report](https://cloud365.io/microsoft-365-security-audit/sample-report/). ## Common questions Does owning Microsoft 365 mean every file is backed up? Do not assume so. Check the actual recovery features, backup policies, supported workloads and accounts included in your organisation’s setup. Is a security audit a restore test? No. Cloud365’s audit is read-only. A restore test needs its own agreed scope, permissions and safe destination. ## More guides [4 November 2026 3 minute read ### Google Workspace to Microsoft 365: Migration Checklist Plan a move from Google Workspace to Microsoft 365.
