ELI5: What is a Backout/Rollback Plan?
It’s like drawing your room layout before rearranging the furniture. If the new layout is terrible, you can look at the drawing and put everything back exactly the way it was.
Definition
A backout (or rollback) plan is a documented set of procedures that outlines how to reverse a change to a system if that change causes unexpected problems or failures. It is a required element of any well-structured change management process, ensuring that systems can be restored to their prior known-good state quickly and reliably when a change goes wrong.
Key Details
- Should be prepared before any change is implemented—not created reactively after a failure.
- Must be tested where possible, especially for critical infrastructure changes.
- Includes: specific steps to revert the change, estimated time to execute, personnel responsible, and validation checks to confirm successful rollback.
- Stored as part of the change request documentation submitted to the Change Advisory Board (CAB).
- Critical for maintenance windows—if rollback can’t be completed within the window, the change may not be approved.
