Backout Plan

Backout Plan

Contingency plan to reverse a deployment or implementation if critical issues arise, ensuring business continuity and minimal disruption.

Backout Plan

A Backout Plan documents how to reverse a deployment or implementation if critical issues are encountered, providing a safety net that enables confident go-live decisions.

Purpose

The Backout Plan:

  • Provides a safety net for deployment
  • Defines criteria for triggering rollback
  • Documents step-by-step reversal process
  • Assigns responsibilities for execution
  • Enables confident go/no-go decisions
  • Minimises business disruption

When to Create

Situation Backout Required
Major deployment Yes
System upgrade Yes
Database changes Yes
Integration changes Yes
Process changes Consider
Configuration changes Consider
Minor patches Risk-based

Rollback verified in staging QA ☐
Team briefed on backout PM ☐

Backup Details

Component Backup Location Verified
Database /backup/db/portal_20260607 ☐
Application files /backup/app/portal_v1.9 ☐
Configuration /backup/config/portal_20260607 ☐

Backout Procedure

Step-by-Step Process

Step Action Owner Duration Verify
1 Announce backout to team PM 2 min Team notified
2 Stop incoming traffic Ops 5 min No new connections
3 Notify users (if applicable) Support 5 min Message displayed
4 Stop application servers Ops 5 min Services stopped
5 Restore database DBA 30 min DB restored
6 Restore application Ops 15 min Files restored
7 Restore configuration Ops 10 min Config restored
8 Start application servers Ops 5 min Services started
9 Verify system health QA 15 min All checks pass
10 Resume traffic Ops 5 min System live
11 Notify stakeholders PM 5 min Comms sent
Total     ~100 min  

Detailed Steps

Step 1: Announce Backout

Action: Announce backout decision to deployment team
Owner: Project Manager
Commands/Actions:
- Call: "Backout invoked. All team members standby."
- Confirm: Each team member acknowledges
Verification: Verbal confirmation from all team members

Step 5: Restore Database

Action: Restore database from pre-deployment backup
Owner: DBA
Commands:
1. Stop database connections
   $ sqlplus / as sysdba
   SQL> ALTER SYSTEM KILL SESSION 'sid,serial#';

2. Restore from backup
   $ rman target /
   RMAN> RESTORE DATABASE;
   RMAN> RECOVER DATABASE;

3. Open database
   SQL> ALTER DATABASE OPEN RESETLOGS;

Verification:
- Run: SELECT COUNT(*) FROM customers;
- Expected: Match pre-deployment count
- Run: SELECT version FROM system_info;
- Expected: v1.9

Step 6: Restore Application

Action: Restore application files from backup
Owner: Operations
Commands:
1. Stop application
   $ systemctl stop portal

2. Remove deployed version
   $ rm -rf /opt/portal/current/*

3. Restore previous version
   $ cp -r /backup/app/portal_v1.9/* /opt/portal/current/

4. Verify files
   $ ls -la /opt/portal/current/

Verification:
- File count matches backup
- Version file shows v1.9

Risk Considerations

Backout Risks

Risk Mitigation
Backup corruption Test backups before deployment
Incomplete restore Verify all components in staging
Data loss (new transactions) Minimal deployment window
Team unavailable Clear on-call roster
Unknown dependencies Thorough impact analysis

Cannot Backout Scenarios

Scenario Alternative
Database schema incompatible Data migration scripts
Third-party changes Coordinate with vendor
Distributed systems Coordinated rollback
Data loss unacceptable Forward-fix only

Alternative Strategies

Fix-Forward vs Backout

Factor Favour Fix-Forward Favour Backout
Time to fix Quick (<1 hour) Long (>2 hours)
Confidence High Low
Risk Low High
Business impact Moderate Severe
Data integrity No risk At risk

Partial Backout

Scenario Approach
Single component failure Rollback that component only
Feature-specific issue Disable feature via config
Performance issue Scale down, investigate
