How your Microsoft 365 backup works and how to ask for a restore
Updated 8 November 2026 · How we workHow-to
Microsoft keeps the service running, but deleted or encrypted data is only recoverable for a limited time. Here is what we back up with Wisecom Atlas and how quickly it comes back.
Why a separate backup
Microsoft 365 is built to stay online, not to be your archive. Deleted mail and files can be recovered for a limited window, and nothing protects you from a mailbox that was emptied by an attacker or files that were encrypted by ransomware and then synced. A separate backup does.
What we back up
Clients on a managed plan have Outlook mailboxes, OneDrive files and SharePoint sites backed up with Wisecom Atlas, an open-source backup engine, to storage we control. Backups run every day. We keep daily copies for 30 days and monthly copies for a year, unless your agreement says otherwise.
Asking for a restore
Email hello@bitnode.tech or call +1 (778) 779-7127 and tell us what is missing, roughly when it was last seen, and where it should go back to. A single message or file is usually back within a few hours during working hours. A whole mailbox or site takes longer and we give you a time estimate before we start.
How you know it works
Every quarter we restore a sample item for each client and record the result. The date of the last successful test restore is on your monthly report, and you can ask for a test restore at any time.
