+# MySQL/MariaDB Point-in-Time Recovery (PITR)
+
+This guide explains how to use dbbackup for Point-in-Time Recovery with MySQL and MariaDB databases.
+
+## Overview
+
+Point-in-Time Recovery (PITR) allows you to restore your database to any specific moment in time, not just to when a backup was taken. This is essential for:
+
+- Recovering from accidental data deletion or corruption
+- Restoring to a state just before a problematic change
+- Meeting regulatory compliance requirements for data recovery
+
+### How MySQL PITR Works
+
+MySQL PITR uses binary logs (binlogs) which record all changes to the database:
+
+1. **Base Backup**: A full database backup with the binlog position recorded
+2. **Binary Log Archiving**: Continuous archiving of binlog files
+3. **Recovery**: Restore base backup, then replay binlogs up to the target time
+
+```
+┌─────────────┐     ┌──────────────┐     ┌──────────────┐     ┌──────────────┐

+```
+
+## Prerequisites
+
+### MySQL Configuration
+
+Binary logging must be enabled in MySQL. Add to `my.cnf`:
+
+```ini
+[mysqld]
+# Enable binary logging
+log_bin = mysql-bin
+server_id = 1
+
+# Recommended: Use ROW format for PITR
+binlog_format = ROW
+
+# Optional but recommended: Enable GTID for easier replication and recovery
+gtid_mode = ON
+enforce_gtid_consistency = ON
+
+# Keep binlogs for at least 7 days (adjust as needed)
+expire_logs_days = 7
+# Or for MySQL 8.0+:
+# binlog_expire_logs_seconds = 604800
+```
+
+After changing configuration, restart MySQL:
+```bash
+sudo systemctl restart mysql
+```
+
+### MariaDB Configuration
+
+MariaDB configuration is similar:
+
+```ini
+[mysqld]
+log_bin = mariadb-bin
+server_id = 1
+binlog_format = ROW
+
+# MariaDB uses different GTID implementation (auto-enabled with log_slave_updates)
+log_slave_updates = ON
+```
+
+## Quick Start
+
+### 1. Check PITR Status
+
+```bash
+# Check if MySQL is properly configured for PITR
+dbbackup pitr mysql-status
+```
+
+Example output:
+```
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+  MySQL/MariaDB PITR Status (mysql)
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+
+PITR Status:     ❌ NOT CONFIGURED
+Binary Logging:  ✅ ENABLED
+Binlog Format:   ROW
+GTID Mode:       ON
+Current Position: mysql-bin.000042:1234
+
+PITR Requirements:
+  ✅ Binary logging enabled
+  ✅ Row-based logging (recommended)
+```
+
+### 2. Enable PITR
+
+```bash
+# Enable PITR and configure archive directory
+dbbackup pitr mysql-enable --archive-dir /backups/binlog_archive
+```
+
+### 3. Create a Base Backup
+
+```bash
+# Create a PITR-capable backup
+dbbackup backup single mydb --pitr
+```
+
+### 4. Start Binlog Archiving
+
+```bash
+# Run binlog archiver in the background
+dbbackup binlog watch --binlog-dir /var/lib/mysql --archive-dir /backups/binlog_archive --interval 30s
+```
+
+Or set up a cron job for periodic archiving:
+```bash
+# Archive new binlogs every 5 minutes
+*/5 * * * * dbbackup binlog archive --binlog-dir /var/lib/mysql --archive-dir /backups/binlog_archive
+```
+
+### 5. Restore to Point in Time
+
+```bash
+# Restore to a specific time
+dbbackup restore pitr mydb_backup.sql.gz --target-time '2024-01-15 14:30:00'
+```
+

+GTID Set: 3E11FA47-71CA-11E1-9E33-C80AA9429562:1-1000
+
+Position String: mysql-bin.000042:123456
+```
+
+## Restore Scenarios
+
+### Restore to Specific Time
+
+```bash
+# Restore to January 15, 2024 at 2:30 PM
+dbbackup restore pitr mydb_backup.sql.gz \
+  --target-time '2024-01-15 14:30:00'
+```
+
+### Restore to Specific Position
+
+```bash
+# Restore to a specific binlog position
+dbbackup restore pitr mydb_backup.sql.gz \
+  --target-position 'mysql-bin.000042:12345'
+```
+
+### Dry Run (Preview)
+
+```bash
+# See what SQL would be replayed without applying
+dbbackup restore pitr mydb_backup.sql.gz \
+  --target-time '2024-01-15 14:30:00' \
+  --dry-run
+```
+
+### Restore to Backup Point Only
+
+```bash
+# Restore just the base backup without replaying binlogs
+dbbackup restore pitr mydb_backup.sql.gz --immediate
+```
+
+## Best Practices
+
+### 1. Archiving Strategy
+
+- Archive binlogs frequently (every 5-30 minutes)
+- Use compression to save disk space
+- Store archives on separate storage from the database
+
+### 2. Retention Policy
+
+- Keep archives for at least as long as your oldest valid base backup
+- Consider regulatory requirements for data retention
+- Use the cleanup command to purge old archives:
+
+```bash
+dbbackup binlog cleanup --archive-dir /backups/binlog_archive --retention-days 30
+```
+
+### 3. Validation
+
+- Regularly validate your binlog chain:
+```bash
+dbbackup binlog validate --binlog-dir /var/lib/mysql
+```
+
+- Test restoration periodically on a test environment
+
+### 4. Monitoring
+
+- Monitor the `dbbackup binlog watch` process
+- Set up alerts for:
+  - Binlog archiver failures
+  - Gaps in binlog chain
+  - Low disk space on archive directory
+
+### 5. GTID Mode
+
+Enable GTID for:
+- Easier tracking of replication position
+- Automatic failover in replication setups
+- Simpler point-in-time recovery
+
+## Troubleshooting
+
+### Binary Logging Not Enabled
+
+**Error**: "Binary logging appears to be disabled"
+
+**Solution**: Add to my.cnf and restart MySQL:
+```ini
+[mysqld]
+log_bin = mysql-bin
+server_id = 1
+```
+
+### Missing Binlog Files
+
+**Error**: "Gaps detected in binlog chain"
+
+**Causes**:
+- `RESET MASTER` was executed
+- `expire_logs_days` is too short
+- Binlogs were manually deleted
+
+**Solution**:
+- Take a new base backup immediately
+- Adjust retention settings to prevent future gaps
+
+### Permission Denied
+
+**Error**: "Failed to read binlog directory"
+
+**Solution**:
+```bash
+# Add dbbackup user to mysql group
+sudo usermod -aG mysql dbbackup_user
+
+# Or set appropriate permissions
+sudo chmod g+r /var/lib/mysql/mysql-bin.*
+```
+
+### Wrong Binlog Format
+
+**Warning**: "binlog_format = STATEMENT (ROW recommended)"
+
+**Impact**: STATEMENT format may not capture all changes accurately
+
+**Solution**: Change to ROW format (requires restart):
+```ini
+[mysqld]
+binlog_format = ROW
+```
+
+### Server ID Changes
+
+**Warning**: "server_id changed from X to Y (possible master failover)"
+
+This warning indicates the binlog chain contains events from different servers, which may happen during:
+- Failover in a replication setup
+- Restoring from a different server's backup
+
+This is usually informational but review your topology if unexpected.
+
+## MariaDB-Specific Notes
+
+### GTID Format
+
+MariaDB uses a different GTID format than MySQL:
+- **MySQL**: `3E11FA47-71CA-11E1-9E33-C80AA9429562:1-5`
+- **MariaDB**: `0-1-100` (domain-server_id-sequence)
+
+### Tool Detection
+
+dbbackup automatically detects MariaDB and uses:
+- `mariadb-binlog` if available (MariaDB 10.4+)
+- Falls back to `mysqlbinlog` for older versions
+
+### Encrypted Binlogs
+
+MariaDB supports binlog encryption. If enabled, ensure the key is available during archive and restore operations.
