Recovery you have already rehearsed.

What is protected

Physical and virtual servers, with image-based backups that can be booted as virtual machines in minutes. Workstations that hold data not stored elsewhere. Microsoft 365 and Google Workspace, including mail, OneDrive and Drive, SharePoint, Teams, and calendars, which the platforms themselves do not back up in the way most owners assume. Line-of-business databases with application-aware snapshots. Network device configurations. And cloud servers in Azure or AWS, replicated across regions.

Why immutability and testing matter

Modern ransomware looks for backups first and encrypts or deletes them before it touches the live data. Immutable storage cannot be altered by anyone, including an administrator whose credentials were stolen, for the retention period. Testing matters because backups fail quietly: a job that reports success can still contain an unusable copy. We restore real data every month and record how long it took, so the recovery time objective in your plan is a measurement rather than an estimate.

How Corewell designs it

We begin by asking two questions for every system: how much data can you afford to lose, and how long can you be without it. Those answers become recovery point and recovery time objectives, and the design follows. Critical servers get local appliances for fast recovery plus cloud copies for disasters. Cloud accounts are backed up to independent storage. Retention is set to meet legal and regulatory requirements. Every job is monitored, every failure is a ticket, and every month we restore files, mailboxes, and at least one full server to confirm the plan works.

When disaster comes

A failed server is booted as a virtual machine on the local appliance or in the cloud within the hour while the hardware is replaced. A ransomware event is recovered from the immutable copy after the environment is cleaned. A flooded or burned office runs from the cloud while employees work from home. The continuity plan names the people, the order of recovery, and the communications to customers and staff, and Corewell runs the technical recovery start to finish.
