Know how your Microsoft 365 data can be restored
Microsoft 365 holds a lot of important business information.


Why use Chrome 365 Backup?
Your email, files, shared folders, Teams content, calendars and user data may all sit at the centre of the working day. Because Microsoft 365 is cloud-based, it is easy to assume everything is already protected in the way your business needs.
That assumption can cause problems.
A file may be deleted by mistake. A mailbox may need restoring after a user leaves. A SharePoint folder may be changed, or an account may be affected by malicious activity. Sometimes the team only notices missing data weeks later.
Chrome helps UK businesses review and support 365 Backup, sometimes called M365 backup or Office 365 backup, so important Microsoft 365 data is easier to recover when something goes wrong.
We’ll help you understand what needs backing up, what is included, how restores work and how backup fits into your wider IT support.
Recover deleted or changed data
Backups can help restore agreed Microsoft 365 data when files, folders or mailboxes are deleted or changed.
Reduce reliance on built-in recovery alone
Microsoft 365 includes retention and recovery features, but these are not always the same as a separate backup service.
Support leavers and account changes
Backup can help when users leave, accounts are changed or mailbox data needs to stay available.
Make recovery clearer
Chrome can help explain what is protected, how long backups are kept and who to contact when something needs restoring.

What is 365 Backup?
365 Backup is a backup as a service offering for agreed Microsoft 365 data.
Depending on the platform and setup, it may help protect Exchange Online email, SharePoint, OneDrive and Teams content.
The purpose is simple: keep a recoverable copy of important Microsoft 365 data through cloud to cloud backup, so your business has clearer options if something is deleted, changed, lost or affected by an incident.
365 Backup is not the same as Microsoft 365 itself.
Microsoft 365 provides cloud services and built-in recovery features, but your business should still understand what those features cover and where a separate Microsoft 365 backup solution may be useful.
A good 365 Backup setup should answer practical questions: what data is backed up, how often backup runs, how long data is kept, who can request a restore, what happens when a user leaves, and what is not included.
Chrome can help you work through those questions before you need the answers in a hurry.
Exchange Online
A recoverable copy of business email.
SharePoint and OneDrive
Files kept recoverable beyond the standard retention period.
Teams content
Conversations and files that live inside Teams.
Cloud to cloud
No local hardware needed to hold the backup.
Why Microsoft 365 data still needs a plan
Microsoft 365 is widely used, but cloud data still needs clear management.
People can delete files by mistake. Users can move folders without realising the impact. Data can be changed, overwritten or removed before anyone notices. A leaver process can also create problems if mailbox or OneDrive data is not handled properly.
Built-in retention settings may help in some situations, but they are not always designed to cover every recovery need.
That is why backup should be planned rather than assumed.
Chrome can help review how your Microsoft 365 data is currently protected and where the gaps may be. We’ll look at the services your team uses, the data that matters most and the recovery situations you are most likely to face.
The aim is not to make backup feel complicated. It is to make sure your business knows what can be restored and what process should be followed.
What can be backed up and restored?
The exact scope depends on the backup service, licence and Microsoft 365 setup.
Chrome can discuss backup for agreed areas such as Exchange Online backup for email, mailboxes and calendars, SharePoint backup for sites and document libraries, OneDrive backup for files and folders, Teams content where supported, Microsoft 365 Groups where supported, deleted or changed files, and user data linked to starters and leavers.
We’ll make clear what is included, what is not included and where another platform or supplier may need to be involved.
This matters because Microsoft 365 is not one simple storage pot. Teams files may live in SharePoint, personal work files may sit in OneDrive and shared mailboxes may need different handling from user mailboxes.
Chrome can explain this in plain English, so your team understands what is protected and where the limits are.
A backup is only useful if the data can be restored when needed. We’ll help you understand how restore requests work, who can request them and what information your team needs to provide, such as the user name, mailbox, folder, file name or date range.
Some restores may be simple, such as recovering a deleted file. Others may be more involved, such as restoring a mailbox, recovering a folder structure or checking data after suspicious account activity.
Backup, retention and leavers
Backup and retention are related, but they are not the same thing.
Retention controls help keep or remove information according to rules. Backup is there to support recovery when agreed data needs to be restored.
Your business may need both, depending on how Microsoft 365 is used and what information needs protecting.
Leavers are a common area where planning matters. When someone leaves, the business may need to keep email, OneDrive files, shared documents or project information. At the same time, access should be removed properly and licences may need reviewing.
Chrome can help connect 365 Backup with starter, leaver and role-change processes. That may include checking mailbox handling, OneDrive access, shared files, group membership and backup coverage.
A clear process helps your team avoid last-minute searches for data that belonged to someone who left months ago.
Backup and cyber security
365 Backup is part of a wider cyber security and recovery setup.
It can support recovery after accidental deletion, malicious activity, account issues or ransomware-related incidents. It should not be treated as the only layer of protection.
Backup works best alongside multi-factor authentication, email security, managed DMARC, password management, device protection, awareness training and user access reviews.
For example, if an account is compromised, your business may need to secure the account, check recent activity, review email rules and restore affected data. If a user deletes or changes data by mistake, backup may help recover the information, while better permissions or user guidance may help reduce repeat issues.
Chrome can help bring these areas together through one team, giving your business a clearer response when something needs attention.
365 Backup and your wider cloud setup
365 Backup rarely sits on its own.
It connects with Microsoft 365, cloud strategy, endpoint backup, device management, managed IT, cyber security and user support.
A lost laptop may involve endpoint backup as well as Microsoft 365 access. A SharePoint restore may involve permissions, user accounts and file structure. A migration project may need backup checked before data is moved.
Chrome can help your team understand what is backed up in Microsoft 365, what is protected elsewhere and where the gaps may be.
We’ll explain what Chrome manages and where another provider remains responsible. That gives your team a clearer place to start when something needs recovering.

Does Microsoft 365 include backup?
Microsoft 365 includes built-in retention and recovery features, but your business should still understand what they cover. A separate Microsoft 365 backup solution may provide clearer restore options for agreed data.
What Microsoft 365 data can be backed up?
This depends on the backup service and licence. Common areas include Exchange email, SharePoint sites, OneDrive files and Teams content where supported.
Can Chrome help restore deleted files or emails?
Yes, where the data is included in the agreed backup service and the restore point is available. Chrome can explain the restore process and what information is needed.
Does 365 Backup replace cyber security?
No. Backup supports recovery, but it should sit alongside account security, email security, awareness training, device protection and wider IT support.
Do you use immutable backup?
Immutable backup, where stored data cannot be changed or deleted within an agreed period, is one of several protections a backup platform may offer. We’ll confirm what your service includes.
Do you know how your Microsoft 365 data would be restored?
Your business may rely on Microsoft 365 every day, but backup and recovery still need a clear plan.
Chrome can help you review what is protected, what needs attention and how restore requests should work.
