+# WebGIS Poverty Mapping - Backup & Recovery Plan
+
+**Version:** 1.0  
+**Last Updated:** May 2026  
+**Classification:** Important
+
+## Executive Summary
+
+This document outlines the backup and recovery strategy for the WebGIS Poverty Mapping application. It ensures business continuity, data protection, and rapid recovery from data loss or system failures.
+
+### Key Objectives
+
+- **Prevent Data Loss:** Regular backups at multiple intervals
+- **Ensure Business Continuity:** Rapid recovery procedures
+- **Minimize Downtime:** RTO ≤ 4 hours, RPO ≤ 1 day
+- **Compliance:** Maintain audit trail and regulatory requirements
+
+---
+
+## 1. Backup Strategy
+
+### 1.1 Backup Schedule
+
+| Backup Type | Frequency | Retention | Storage |
+|-------------|-----------|-----------|---------|
+| **Full Daily** | Every day at 2:00 AM | 7 days | Local + Network Drive |
+| **Weekly** | Every Sunday at 3:00 AM | 4 weeks | Local + External HDD |
+| **Monthly** | First day of month at 4:00 AM | 1 year | External HDD Archive |
+| **Transaction Log** | Hourly (if available) | 3 days | Local |
+
+### 1.2 Backup Methods
+
+#### Method 1: MySQL Dump (Recommended)
+
+```bash
+# Full database backup
+mysqldump -u root -p --single-transaction --result-file=/backup/webgis_full_$(date +%Y%m%d).sql webgis_unified
+
+# With compression (smaller file)
+mysqldump -u root -p webgis_unified | gzip > /backup/webgis_full_$(date +%Y%m%d).sql.gz
+```
+
+#### Method 2: Scheduled Backup Script
+
+Create `/backup/backup.sh`:
+
+```bash
+#!/bin/bash
+
+# Configuration
+DB_NAME="webgis_unified"
+DB_USER="root"
+DB_PASSWORD="YourPassword"
+BACKUP_DIR="/backup"
+DATE=$(date +%Y%m%d_%H%M%S)
+BACKUP_FILE="$BACKUP_DIR/webgis_backup_$DATE.sql"
+
+# Create backup
+echo "Starting backup: $DATE"
+mysqldump -u $DB_USER -p$DB_PASSWORD $DB_NAME > $BACKUP_FILE
+
+# Compress
+gzip $BACKUP_FILE
+BACKUP_FILE="${BACKUP_FILE}.gz"
+
+# Check file size
+SIZE=$(du -h $BACKUP_FILE | cut -f1)
+echo "Backup completed: $BACKUP_FILE ($SIZE)"
+
+# Remove old backups (keep 7 days)
+find $BACKUP_DIR -name "webgis_backup_*.sql.gz" -mtime +7 -delete
+
+# Copy to network drive (optional)
+cp $BACKUP_FILE /mnt/network_backup/
+
+# Verify backup
+if gzip -t $BACKUP_FILE; then
+    echo "Backup verification: SUCCESS"
+else
+    echo "Backup verification: FAILED" | mail -s "Backup Failed" admin@example.com
+fi
+```
+
+#### Method 3: Automated Cron Job
+
+Edit crontab:
+
+```bash
+crontab -e
+```
+
+Add:
+
+```cron
+# Daily backup at 2:00 AM
+0 2 * * * /backup/backup.sh
+
+# Weekly backup (Sunday 3:00 AM)
+0 3 * * 0 /backup/backup_weekly.sh
+
+# Monthly backup (1st day 4:00 AM)
+0 4 1 * * /backup/backup_monthly.sh
+```
+
+### 1.3 Backup Storage
+
+#### Local Storage
+
+```
+/backup/
+├── webgis_backup_20260520_020000.sql.gz
+├── webgis_backup_20260519_020000.sql.gz
+├── webgis_backup_20260518_020000.sql.gz
+└── ... (7 days of daily backups)
+```
+
+#### Network Storage
+
+```
+/mnt/network_backup/
+├── Daily/    (7 copies)
+├── Weekly/   (4 copies)
+└── Monthly/  (12 copies)
+```
+
+#### External HDD
+
+- Store weekly and monthly backups
+- Keep in secure location (fire-proof safe recommended)
+- Update quarterly
+
+### 1.4 File-Level Backup
+
+```bash
+# Backup application files

+
+# Backup PHP configuration
+tar -czf /backup/php_config_$(date +%Y%m%d).tar.gz /etc/php/
+
+# Backup Apache configuration
+tar -czf /backup/apache_config_$(date +%Y%m%d).tar.gz /etc/apache2/
+```
+
+---
+
+## 2. Recovery Procedures
+
+### 2.1 Full Recovery (Complete Restore)
+
+**Scenario:** Database completely corrupted or lost
+
+**Time to Recover:** 30-60 minutes
+
+**Steps:**
+
+1. **Stop Application**
+   ```bash
+   sudo systemctl stop apache2
+   ```
+
+2. **Backup Current Database** (if possible)
+   ```bash
+   mysqldump -u root -p webgis_unified > current_backup_$(date +%Y%m%d).sql
+   ```
+
+3. **Drop Current Database**
+   ```bash
+   mysql -u root -p
+   DROP DATABASE webgis_unified;
+   ```
+
+4. **Restore from Backup**
+   ```bash
+   # Unzip if compressed
+   gunzip /backup/webgis_backup_20260520.sql.gz
+   
+   # Restore
+   mysql -u root -p < /backup/webgis_backup_20260520.sql
+   ```
+
+5. **Verify Recovery**
+   ```bash
+   mysql -u root -p
+   USE webgis_unified;
+   SHOW TABLES;
+   SELECT COUNT(*) FROM data_unified;
+   ```
+
+6. **Restart Application**
+   ```bash
+   sudo systemctl start apache2
+   ```
+
+7. **Test Application**
+   - Access http://localhost/webgis/
+   - Verify data is present
+   - Check recent data
+
+### 2.2 Partial Recovery (Selective Tables)
+
+**Scenario:** Only specific tables corrupted
+
+**Time to Recover:** 15-30 minutes
+
+**Steps:**
+
+1. **Export Specific Table from Backup**
+   ```bash
+   # Extract table from backup
+   gunzip -c /backup/webgis_backup_20260520.sql.gz | \
+   mysql -u root -p -e "USE webgis_unified; SOURCE /dev/stdin"
+   ```
+
+2. **Or Restore Specific Table**
+   ```bash
+   # Create temporary database
+   mysql -u root -p -e "CREATE DATABASE temp_restore"
+   
+   # Restore backup to temporary DB
+   mysql -u root -p temp_restore < /backup/webgis_backup_20260520.sql
+   
+   # Copy specific table
+   mysql -u root -p -e "
+   USE webgis_unified;
+   DROP TABLE IF EXISTS data_unified;
+   RENAME TABLE temp_restore.data_unified TO webgis_unified.data_unified;
+   "
+   
+   # Drop temporary DB
+   mysql -u root -p -e "DROP DATABASE temp_restore"
+   ```
+
+### 2.3 Point-in-Time Recovery (Specific Date/Time)
+
+**Scenario:** Need to recover data from specific point in time
+
+**Requirements:** Transaction logs or multiple daily backups
+
+**Steps:**
+
+1. **Identify Target Point in Time**
+   ```bash
+   # Example: Recover to May 18, 2:00 PM
+   TARGET_DATE="2026-05-18 14:00:00"
+   ```
+
+2. **Restore Latest Backup Before Target**
+   ```bash
+   # Find appropriate backup
+   ls -la /backup/webgis_backup_20260518*.sql.gz
+   ```
+
+3. **Restore Full Backup**
+   ```bash
+   mysql -u root -p webgis_unified < /backup/webgis_backup_20260518_020000.sql
+   ```
+
+4. **Apply Transaction Log** (if available)
+   ```bash
+   # Apply changes up to target time
+   # Requires binary logging to be enabled
+   ```
+
+### 2.4 Disaster Recovery (System-Wide Failure)
+
+**Scenario:** Entire server lost
+
+**Time to Recover:** 2-4 hours

+   - Verify data integrity
+
+---
+
+## 3. Backup Verification
+
+### 3.1 Regular Testing
+
+**Monthly Backup Test:** (1st Sunday of each month)
+
+```bash
+#!/bin/bash
+# Test backup by restoring to test database
+
+echo "Starting monthly backup test..."
+
+# Create test database
+mysql -u root -p -e "DROP DATABASE IF EXISTS webgis_test; CREATE DATABASE webgis_test;"
+
+# Restore latest backup
+LATEST_BACKUP=$(ls -t /backup/webgis_backup_*.sql.gz | head -1)
+gunzip -c $LATEST_BACKUP | mysql -u root -p webgis_test
+
+# Verify
+RECORD_COUNT=$(mysql -u root -p -e "USE webgis_test; SELECT COUNT(*) FROM data_unified;")
+
+if [ "$RECORD_COUNT" -gt 0 ]; then
+    echo "Backup test PASSED - Restored $RECORD_COUNT records"
+    mail -s "Backup Test Passed" admin@example.com
+else
+    echo "Backup test FAILED"
+    mail -s "ALERT: Backup Test Failed" admin@example.com
+fi
+
+# Cleanup
+mysql -u root -p -e "DROP DATABASE webgis_test;"
+```
+
+### 3.2 Integrity Checks
+
+```bash
+# Check backup file integrity
+gzip -t /backup/webgis_backup_20260520.sql.gz
+
+# Verify backup size
+du -h /backup/webgis_backup_20260520.sql.gz
+
+# Test restore to temporary location
+mysql -u root -p -e "CREATE DATABASE test_restore"
+gunzip -c /backup/webgis_backup_20260520.sql.gz | mysql -u root -p test_restore
+mysql -u root -p test_restore -e "SELECT COUNT(*) FROM data_unified"
+mysql -u root -p -e "DROP DATABASE test_restore"
+```
+
+### 3.3 Audit Trail Verification
+
+```sql
+-- Verify audit log is being populated
+SELECT COUNT(*) FROM audit_log;
+
+-- Check recent activity
+SELECT * FROM audit_log ORDER BY changed_at DESC LIMIT 10;
+
+-- Verify data consistency
+SELECT COUNT(*) FROM data_unified;
+SELECT COUNT(DISTINCT tipe) FROM data_unified;
+```
+
+---
+
+## 4. Retention Policy
+
+### 4.1 Backup Retention
+
+| Backup Type | Retention Period | Storage Location |
+|-------------|-----------------|-----------------|
+| Daily | 7 days | Local server |
+| Weekly | 4 weeks | Network drive |
+| Monthly | 1 year | External HDD |
+| Quarterly Archive | 7 years | Off-site (optional) |
+
+### 4.2 Data Retention
+
+```sql
+-- Archive old audit logs (older than 1 year)
+DELETE FROM audit_log WHERE changed_at < DATE_SUB(NOW(), INTERVAL 1 YEAR);
+
+-- Archive old statistics
+DELETE FROM data_statistics WHERE stat_date < DATE_SUB(CURDATE(), INTERVAL 1 YEAR);
+```
+
+### 4.3 Cleanup Script
+
+```bash
+#!/bin/bash
+
+# Remove backups older than 7 days
+find /backup -name "webgis_backup_*.sql.gz" -mtime +7 -exec rm {} \;
+
+# Remove backups older than 30 days from network drive
+find /mnt/network_backup -name "webgis_backup_*.sql.gz" -mtime +30 -exec rm {} \;
+
+# Archive monthly backups to external HDD (optional)
+find /backup -name "webgis_backup_*.sql.gz" -mtime +30 -exec cp {} /mnt/external_hdd/archive/ \;
+```
