**"Permission denied"** - Check database user privileges or run with appropriate system user- Verification of required tools (psql, pg_restore, tar, gzip)
|
||||
|
||||
|
||||
|
||||
**"Disk space check failed"** - Ensure sufficient space in backup directory (4x archive size recommended)- Automatic detection and cleanup of existing databases (interactive mode)SSL modes: `disable`, `prefer`, `require`, `verify-ca`, `verify-full`

## Requirements### Environment Variables
|

|
||||
|

|

### System Requirements**Warning:** This is a destructive operation. Only use in test environments or genuine disaster recovery scenarios.
|
||||
|
||||
|
||||
|
||||
- Linux, macOS, FreeBSD, OpenBSD, or NetBSD```bash
|
||||
|
||||
- 1 GB RAM minimum (2 GB recommended for large databases)
|
||||
|
||||
- Sufficient disk space for backups (typically 30-50% of database size)## Configuration# Database
|
||||
|
||||
|
||||
|
||||
### Software Requirementsexport PG_HOST=localhost
|
||||
|
||||
|
||||
|
||||
#### PostgreSQL### PostgreSQL Authenticationexport PG_PORT=5432
|
||||
|
||||
- PostgreSQL client tools (psql, pg_dump, pg_dumpall, pg_restore)
|
||||
|
||||
- PostgreSQL 10 or later recommendedexport PG_USER=postgres
|
||||
|
||||
|
||||
|
||||
#### MySQL/MariaDBPostgreSQL authentication varies by system configuration. The tool automatically detects issues and provides solutions.export PGPASSWORD=secret
|
||||
|
||||
- MySQL/MariaDB client tools (mysql, mysqldump)
|
||||
|
||||
- MySQL 5.7+ or MariaDB 10.3+ recommendedexport MYSQL_HOST=localhost
|
||||
|
||||
|
||||
|
||||
#### Optional#### Peer/Ident Authentication (Default on Linux)export MYSQL_PWD=secret
|
||||
|
||||
- pigz (for parallel compression)
|
||||
|
||||
- pv (for progress monitoring)
|
||||
|
||||
|
||||
|
||||
## Best PracticesRun as the PostgreSQL system user:# Backup
|
||||
|
||||
|
||||
|
||||
1. **Test Restores Regularly** - Verify backups can be restored successfullyexport BACKUP_DIR=/var/backups
|
||||
|
||||
2. **Monitor Disk Space** - Ensure adequate space for backup operations
|
||||
|
||||
3. **Use Compression** - Balance between speed and space (level 3-6 recommended)```bashexport COMPRESS_LEVEL=6
|
||||
|
||||
4. **Automate Backups** - Schedule regular backups via cron or systemd timers
|
||||
|
||||
5. **Secure Credentials** - Use .pgpass or .my.cnf files with proper permissions (0600)sudo -u postgres ./dbbackup backup clusterexport CLUSTER_TIMEOUT_MIN=240 # Cluster timeout in minutes
|
||||
|
||||
6. **Version Control** - Keep multiple backup versions for point-in-time recovery
|
||||
|
||||
7. **Off-Site Storage** - Copy backups to remote storage for disaster recovery```
|
||||
|
||||
8. **Document Procedures** - Maintain runbooks for restore operations
|
||||
|
||||

# MySQL/MariaDB
|
||||
## Why dbbackup?
|
||||
|
||||
export MYSQL_HOST=localhost**Authentication Errors (PostgreSQL):**
|
||||
**Test connectivity:**
|
||||
|
||||
export MYSQL_PORT=3306
|
||||
- **Reliable**: Comprehensive safety checks, validation, and error handling
|
||||
|
||||
export MYSQL_USER=rootIf you see: `FATAL: Peer authentication failed for user "postgres"` or `FATAL: Ident authentication failed`
|
||||
- **Simple**: Intuitive menu-driven interface or straightforward CLI```bash
|
||||
|
||||
export MYSQL_PWD=password
|
||||
- **Fast**: Automatic CPU detection, parallel processing, streaming compression./dbbackup status
|
||||
|
||||
The tool will automatically show you 4 solutions:
|
||||
- **Efficient**: Minimal memory footprint, even for huge databases```
|
||||
|
||||
# General1. Run as matching OS user: `sudo -u postgres dbbackup`
|
||||
- **Flexible**: Multiple backup modes, compression levels, performance options
|
||||
|
||||
export BACKUP_DIR=/var/backups/databases2. Configure ~/.pgpass file (recommended for automation)
|
||||
- **Safe**: Dry-run by default, archive verification, smart database cleanup**PostgreSQL peer authentication error:**
|
||||
|
||||
export COMPRESS_LEVEL=63. Set PGPASSWORD environment variable
|
||||
|
||||
export CLUSTER_TIMEOUT_MIN=2404. Use --password flag
|
||||
|
||||
```
|
||||
|
||||
**Test connection:**
|
||||
|
||||
## Performance```bash
|
||||
|
||||
dbbackup status
|
||||
|
||||
### CPU Optimization
|
||||
|
||||
# Disable SSL
|
||||
|
||||
The tool automatically detects CPU configuration and optimizes parallel operations:dbbackup status --insecure
|
||||
|
||||
|
||||
|
||||
```bash# Use postgres user (Linux)
|
||||
|
||||
./dbbackup cpusudo -u postgres dbbackup status
|
||||
|
||||
``````
|
||||
|
||||
|
||||
|
||||
Manual override:### Out of Memory Issues
|
||||
- **Complete**: Full cluster backup/restore, point-in-time recovery, multiple formats
|
||||
|
||||
```bash
|
||||
|
||||
./dbbackup backup cluster --max-cores 32 --jobs 32 --cpu-workload cpu-intensiveCheck kernel logs for OOM events:
|
||||
|
||||
``````bash
|
||||
|
||||
dmesg | grep -i oom
|
||||
|
||||
### Memory Usagefree -h
|
||||
dbbackup is production-ready for backup and disaster recovery operations on PostgreSQL, MySQL, and MariaDB databases of any size.sudo -u postgres ./dbbackup status
|
||||
|
||||
```
|
||||
|
||||
Streaming architecture maintains constant memory usage:
|
||||
|
||||
Enable swap file management (Linux + root):
|
||||
|
||||
| Database Size | Memory Usage |```bash
|
||||
|
||||
|---------------|--------------|export AUTO_SWAP=true
|
||||
|
||||
| 1-10 GB | ~800 MB |export SWAP_FILE_SIZE_GB=8
|
||||
|
||||
| 10-50 GB | ~900 MB |sudo dbbackup backup cluster
|
||||
|
||||
| 50-100 GB | ~950 MB |```
|
||||
|
||||
| 100+ GB | <1 GB |
|
||||
|
||||
Or manually add swap:
|
||||
|
||||
### Large Database Support```bash
|
||||
|
||||
sudo fallocate -l 8G /swapfile
|
||||
|
||||
- Databases >5GB automatically use optimized plain format with streaming compressionsudo chmod 600 /swapfile
|
||||
|
||||
- Parallel compression via pigz (if available) for maximum throughputsudo mkswap /swapfile
|
||||
|
||||
- Per-database timeout configuration (default: 4 hours)sudo swapon /swapfile
|
||||
|
||||
- Automatic format selection based on size```

||||
```bash
|
||||
free -h
|
||||
dmesg | grep -i oom
|
||||
```
|
||||
|
||||
2. Add swap space:

## Best Practices
|
||||
|
||||
1. **Test Restores Regularly** - Verify backups can be restored successfully
|
||||
2. **Monitor Disk Space** - Ensure adequate space for backup operations
|
||||
3. **Use Compression** - Balance between speed and space (level 3-6 recommended)
|
||||
4. **Automate Backups** - Schedule regular backups via cron or systemd timers
|
||||
5. **Secure Credentials** - Use .pgpass or .my.cnf files with proper permissions (0600)
|
||||
6. **Version Control** - Keep multiple backup versions for point-in-time recovery
|
||||
7. **Off-Site Storage** - Copy backups to remote storage for disaster recovery
|
||||
8. **Document Procedures** - Maintain runbooks for restore operations
|
||||
1. **Test restores regularly** - Verify backups work
|
||||
2. **Monitor disk space** - Ensure adequate space
|
||||
3. **Use compression** - Balance speed/space (level 3-6)
|
||||
4. **Automate backups** - cron or systemd timers
|
||||
5. **Secure credentials** - .pgpass/.my.cnf with 0600 permissions
|
||||
6. **Keep versions** - Multiple backup versions for point-in-time recovery
|
||||
7. **Off-site storage** - Remote backup copies
|
||||
8. **Document procedures** - Maintain restore runbooks
