Backup Strategy - Task 2.4

Task 2.4: Create Backup Strategy

Date: 2025-01-23 Purpose: Establish comprehensive backup plan to ensure no data loss during JAEGIS project reorganization

Backup Strategy Overview

🎯 Multi-Level Backup Approach

1. Complete project backup before any changes

2. Incremental backups at each phase

3. Critical file snapshots before high-risk operations

4. Rollback-ready backups with quick restore capability

Backup Levels and Scope

🔒 Level 1: Complete Project Backup

Full System Snapshot

Backup scope: Entire JAEGIS project directory
Backup location: JAEGIS-backup-YYYYMMDD-HHMMSS/
Backup method: Complete directory copy
Timing: Before any reorganization begins

Files included:
  - All source files (src/)
  - All documentation (docs/, JAEGIS-agent/*.md)
  - All scripts (*.ps1, *.bat, *.sh, *.py, *.js)
  - All configuration (*.json, *.cfg, *.service)
  - Build artifacts (dist/, out/)
  - Dependencies (node_modules/) - optional
  - Logs and diagnostics

Files excluded:
  - Temporary files (__pycache__/)
  - Large dependencies (node_modules/) - if space constrained
  - Build caches
  - User-specific files

Backup Verification

Verification steps:
  1. Compare file counts (original vs backup)
  2. Verify critical files exist in backup
  3. Check file sizes match
  4. Validate backup directory structure
  5. Test restore capability

Critical files to verify:
  - JAEGIS-agent/agent-config.txt
  - package.json
  - tsconfig.json
  - webpack.config.js
  - All .md documentation files
  - All script files

🔄 Level 2: Phase-Based Incremental Backups

Phase Backup Strategy

Phase 1 Backup (Before file copying):
  - Backup location: JAEGIS-backup-phase1-YYYYMMDD/
  - Scope: Current state before any file movement
  - Purpose: Rollback point for file movement issues

Phase 2 Backup (After file copying, before reference updates):
  - Backup location: JAEGIS-backup-phase2-YYYYMMDD/
  - Scope: State with files copied but references unchanged
  - Purpose: Rollback point for reference update issues

Phase 3 Backup (After reference updates, before validation):
  - Backup location: JAEGIS-backup-phase3-YYYYMMDD/
  - Scope: State with files moved and references updated
  - Purpose: Rollback point for validation issues

Phase 4 Backup (After validation, before cleanup):
  - Backup location: JAEGIS-backup-phase4-YYYYMMDD/
  - Scope: State with everything working, before original file removal
  - Purpose: Final safety backup before cleanup

📁 Level 3: Critical File Snapshots

High-Risk File Backups

Critical files requiring individual snapshots:

1. agent-config.txt
   - Backup: JAEGIS-agent/agent-config.txt.backup.YYYYMMDD
   - Reason: Core system configuration
   - Restore priority: CRITICAL

2. package.json
   - Backup: package.json.backup.YYYYMMDD
   - Reason: Build system and extension configuration
   - Restore priority: CRITICAL

3. tsconfig.json
   - Backup: tsconfig.json.backup.YYYYMMDD
   - Reason: TypeScript compilation configuration
   - Restore priority: HIGH

4. webpack.config.js
   - Backup: webpack.config.js.backup.YYYYMMDD
   - Reason: Build system configuration
   - Restore priority: HIGH

5. enhanced-JAEGIS-orchestrator-instructions.md
   - Backup: JAEGIS-agent/enhanced-JAEGIS-orchestrator-instructions.md.backup.YYYYMMDD
   - Reason: Primary user documentation
   - Restore priority: HIGH

Snapshot Timing

Before each critical operation:
  - Before moving configuration files
  - Before updating package.json
  - Before updating tsconfig.json
  - Before updating webpack.config.js
  - Before updating core documentation

Backup Implementation Strategy

📋 Implementation Method: Documentation-Based

Since direct file operations are limited, we'll use a documentation-based backup approach:

Step 1: Document Current State

Create comprehensive documentation of:
  1. Current file locations and contents
  2. Current directory structure
  3. Current reference mappings
  4. Current system configuration
  5. Current functionality baseline

Documentation files:
  - current-state-snapshot.md
  - file-location-registry.md
  - reference-mapping-current.md
  - system-configuration-baseline.md

Step 2: Create Backup Manifests

Backup manifests to create:
  1. complete-file-inventory.md - All files with checksums
  2. critical-file-contents.md - Contents of critical files
  3. directory-structure-map.md - Current directory structure
  4. reference-dependency-map.md - All file references

Purpose:
  - Enable manual restoration if needed
  - Provide rollback reference
  - Document system state for comparison

Step 3: Validation Baselines

Create baseline documentation:
  1. functionality-test-results.md - Current system functionality
  2. build-system-status.md - Current build system state
  3. extension-loading-status.md - Current extension status
  4. user-interface-status.md - Current UI functionality

Purpose:
  - Compare against after changes
  - Validate restoration success
  - Ensure no functionality loss

🔧 Backup Validation Process

Backup Completeness Check

Validation checklist:
  □ All critical files documented
  □ File contents captured
  □ Directory structure mapped
  □ Reference dependencies documented
  □ System state baseline established
  □ Functionality baseline captured
  □ Rollback procedures documented

Backup Accessibility Test

Test procedures:
  1. Verify backup documentation is readable
  2. Test sample file restoration process
  3. Validate backup manifest accuracy
  4. Confirm rollback procedure clarity
  5. Test baseline comparison process

Rollback Procedures

🔄 Rollback Triggers

Immediate rollback required for:
  - Core system functionality failure
  - Build system complete failure
  - Extension loading failure
  - User interface completely broken
  - Multiple critical system failures

Conditional rollback for:
  - Performance degradation >20%
  - Partial functionality loss
  - User experience significantly impacted
  - Documentation navigation broken

🚨 Rollback Execution

Level 1: Reference Rollback

Scope: Revert reference changes only
Process:
  1. Restore original file references
  2. Update paths back to original locations
  3. Test functionality
  4. Validate system operation

Time required: 15-30 minutes
Risk: LOW

Level 2: File Location Rollback

Scope: Move files back to original locations
Process:
  1. Copy files back to original locations
  2. Remove files from new locations
  3. Restore original references
  4. Test complete functionality

Time required: 30-60 minutes
Risk: MEDIUM

Level 3: Complete System Rollback

Scope: Restore entire system to original state
Process:
  1. Restore all files to original locations
  2. Restore all original references
  3. Remove new directory structure
  4. Validate complete system functionality
  5. Verify baseline functionality

Time required: 1-2 hours
Risk: LOW (using documented backup)

Recovery Testing

🧪 Recovery Validation

Test scenarios:
  1. Single file restoration
  2. Phase rollback simulation
  3. Complete system restoration
  4. Reference-only rollback
  5. Critical file recovery

Test frequency:
  - Before reorganization begins
  - After each major phase
  - Before final cleanup

✅ Recovery Success Criteria

Success metrics:
  - 100% file restoration accuracy
  - 100% functionality preservation
  - 0% data loss
  - <2 hour complete recovery time
  - <30 minute reference rollback time

  5. Test backup documentation completeness

Timeline: 1-2 hours before reorganization

Phase 2: Ongoing Backup Maintenance

Tasks:
  1. Create phase-specific backups
  2. Update backup documentation
  3. Validate backup completeness
  4. Test rollback procedures
