Microsoft doesn't back up your data the way you think
Microsoft 365 keeps your services running, but under its shared responsibility model, protecting your data is your job. Deleted items and version history are kept for limited periods, and if an attacker or an angry employee deletes or encrypts files, those copies may not save you. A separate Microsoft 365 backup covers Exchange, OneDrive, SharePoint and Teams, with point-in-time restores going back as far as you choose.
Immutable means ransomware can't touch it
Modern ransomware hunts for backups and deletes them first. Immutable backups are written so that nobody, including an attacker with admin passwords, can change or delete them until the retention period ends. Combined with backups stored off-site and outside your main accounts, that's the copy that gets you back.
Disaster recovery is a plan, not a product
We document what needs to come back first, how long you can be down (your recovery time objective), and how much data you can afford to lose (your recovery point objective). Then we test restores on a schedule and send you the results. A backup you haven't tested is a hope, not a plan.
