What does Acronis Cyber Backup Advanced Microsoft 365 do?

It makes scheduled, cloud-to-cloud copies of your Microsoft 365 tenant and lets you restore them when data is lost. The backup agent runs inside the Acronis Cloud and pulls data straight from Microsoft's data centers to Acronis data centers, so nothing is installed on your premises. It covers Exchange Online, OneDrive for Business, SharePoint Online and Microsoft Teams in one configuration. This matters because Microsoft's native recycle bin and retention windows expire, after which an accidentally deleted mailbox or a ransomware-encrypted file is gone unless you hold a separate backup.

Which Microsoft 365 data does it back up?

It protects Exchange Online, OneDrive for Business, SharePoint Online and Microsoft Teams. Exchange backups include emails, attachments, contacts, tasks, calendars, plus group and archive mailboxes, while OneDrive and SharePoint backups keep their access permissions, and SharePoint captures site collections, team sites and communication sites. That permission-aware coverage means a departed employee's mailbox or a deleted SharePoint site can be rebuilt with its sharing structure intact. For an admin, this avoids re-creating folder permissions by hand after a restore.

Does it cover Teams and SharePoint, not just email?

Yes, Microsoft Teams and SharePoint Online are included alongside Exchange and OneDrive. SharePoint site collections, team sites, communication sites and their permission settings are captured, and Teams content can be searched directly inside the backups. Teams channel files and a deleted team are a frequent blind spot, because native 365 retention often cannot bring a removed team back once it ages out. With this edition you can locate and restore that material instead of relying on Microsoft's limited recovery window.

Why is Microsoft 365 backup only available in the Advanced edition?

Microsoft 365 cloud-to-cloud backup is supported only in the Acronis Cyber Protect Backup Advanced edition, not the Standard tier. Acronis licenses it per seat and bundles unlimited Acronis Cloud storage for the 365 workload. If you were comparing this to a cheaper Standard license expecting it to include 365 protection, that tier does not cover cloud-to-cloud Microsoft 365 backup at all. Advanced is therefore the entry point for protecting Exchange, OneDrive, SharePoint and Teams.

What does Acronis Cyber Backup Advanced Microsoft 365 not protect?

It backs up Microsoft 365 cloud data only and does not protect local PCs, on-premises servers, or other non-365 workloads. It is a backup-and-recovery edition, so the endpoint detection and anti-malware tools (EDR) found in the separate Cyber Protect Advanced edition are not part of it. If you also need to image laptops or a Windows file server, you would add a device-based Acronis license, since this product alone will not cover them. Checking which workloads you actually need to protect before buying avoids assuming this single license covers your whole environment.

How fast can you recover a deleted mailbox or file?

Recovery is granular, so you restore a single email, file, folder or whole site without rolling back everything else. You can preview email content, download attachments or send an email straight from the backup, and download files directly from a OneDrive backup. Mailbox search lets you find items by subject, sender, recipient or date, including partial matches. In practice a helpdesk can return one accidentally deleted message in minutes rather than restoring an entire mailbox and overwriting newer mail.

Frequently asked questions about Acronis Cyber Backup Advanced Microsoft 365

Does Microsoft already back up Microsoft 365 for me?

No. Microsoft runs a shared-responsibility model where it keeps the service available but leaves protection of your content to you, and it recommends backing up data with a third-party service. Native recycle bins and retention policies only hold items for a limited time before they are purged for good. A dedicated 365 backup like this one keeps independent copies you control.

Where is my backup data stored?

Backups are written to secure Acronis Cloud data centers, copied directly from Microsoft's data centers in a cloud-to-cloud flow. Because the agent runs in the Acronis Cloud, you do not need local storage hardware or an on-premises backup server. The Microsoft 365 workload includes unlimited Acronis Cloud storage, so mailbox and file growth does not require buying extra capacity.
