PS-Backup: Complete Guide to Features & SetupPS-Backup is a modern backup solution designed to protect data across desktops, servers, and cloud environments. This guide covers core features, system requirements, installation, configuration, backup strategies, recovery procedures, security considerations, performance tuning, troubleshooting, and best practices to help administrators and power users implement reliable, maintainable backups.
What PS-Backup Does
PS-Backup performs scheduled and on-demand backups, supports full, incremental, and differential modes, can target local storage, network shares, and cloud providers, and offers encryption, compression, and deduplication. It provides a command-line interface (CLI) for automation and a web-based dashboard for monitoring and restores.
Key Features
- Full, Incremental, Differential Backups — choose the strategy that balances speed and storage.
- Cross-Platform Support — Windows, macOS, and major Linux distributions.
- Multiple Targets — local disks, NAS, S3-compatible cloud storage, and FTP/SFTP.
- Encryption at Rest and In Transit — AES-256 for stored data; TLS for network transfers.
- Compression & Deduplication — reduces storage footprint and transfer times.
- Versioning & Retention Policies — configurable retention rules and automatic pruning.
- Scheduling & Alerts — cron-like scheduling and email/SMS/ webhook notifications.
- CLI & REST API — for automation, orchestration, and integration with CI/CD pipelines.
- Web Dashboard — visual monitoring, job history, and guided restores.
- Agentless & Agent-Based Modes — agent for application-aware backups (databases, Exchange, VMs); agentless for file-level snapshots via network mounts.
- Integrity Checks & Test Restores — verify backups automatically and perform randomized test restores.
System Requirements
- CPU: Dual-core minimum; quad-core recommended for large workloads.
- RAM: 4 GB minimum; 8+ GB recommended for deduplication and compression-heavy tasks.
- Disk: Local install 1–2 GB; additional space for temporary staging during backups.
- Network: 1 Gbps recommended for high-volume transfers; TLS-capable endpoints for cloud targets.
- Supported OS versions: Recent LTS releases of Ubuntu/Debian/CentOS/RHEL, Windows Server 2016+, macOS 10.14+.
Installation
Below are general installation steps. Follow vendor-specific docs for packaged installers.
Linux (example using a Debian package):
wget https://example.com/ps-backup/latest/ps-backup.deb sudo dpkg -i ps-backup.deb sudo systemctl enable --now ps-backup Windows (MSI installer):
- Run the MSI and follow the installer wizard.
- Choose Install Location and whether to install the service.
- Start the PS-Backup Service from Services.msc or the provided shortcut.
macOS (Homebrew / PKG):
brew install ps-backup sudo launchctl load /Library/LaunchDaemons/com.psbackup.plist Initial Configuration
- Access the web dashboard at http://localhost:8080 (or the host’s IP) and log in with the default admin account.
- Change the default admin password immediately.
- Add storage targets:
- Local path or mounted network share.
- S3-compatible endpoint: provide Access Key, Secret Key, bucket name, and region.
- FTP/SFTP: hostname, port, credentials.
- Configure encryption keys:
- Generate a new AES-256 key or upload your own.
- Decide where to store the key: local keystore, HSM, or KMS (AWS KMS, Azure Key Vault).
- Set up notification channels (email SMTP, Slack, webhooks).
- Register agents on hosts that require application-aware backups.
Backup Types & When to Use Them
- Full backup: Complete copy of selected data. Use periodically (weekly/monthly) as a baseline.
- Incremental backup: Backs up only changes since the last backup of any kind. Best for daily backups to save time/storage.
- Differential backup: Backs up changes since the last full backup. Simpler restore chain than incremental; larger than incremental.
Example strategy:
- Weekly full backups + daily incrementals + monthly archival full stored offsite.
Scheduling and Retention
- Use PS-Backup’s scheduler for daily/weekly/monthly jobs; support for cron expressions for complex schedules.
- Retention policy examples:
- Keep last 7 daily incrementals.
- Keep last 4 weekly full backups.
- Archive monthly full backups for 12 months.
- Implement lifecycle rules for cloud targets to transition older backups to cheaper storage classes and then to deletion.
Encryption, Security, and Access Control
- Encrypt backups client-side with AES-256 before upload; ensure keys are stored securely and backed up.
- Use TLS 1.2+ for all network communications.
- Limit access with role-based access control (RBAC): admins, operators, auditors with least privilege.
- Enable MFA for dashboard logins.
- Regularly rotate credentials and encryption keys according to policy.
- Enable audit logging for admin actions and restores.
Restores & Disaster Recovery
- File-level restore: select files/folders and restore to original or alternate path.
- Full system restore: boot from recovery media and apply the latest full backup and subsequent incrementals/differentials.
- Bare-metal restore: supported for Windows and Linux with driver injection for different hardware.
- Database-aware restores: quiesce databases, apply transaction logs if supported (e.g., for PostgreSQL, SQL Server).
- Test restores monthly and after major changes; maintain playbooks describing RTO (Recovery Time Objective) and RPO (Recovery Point Objective).
Performance Tuning
- Use deduplication and compression sensibly: dedupe saves bandwidth/storage at CPU cost.
- Staging area: use fast local SSDs for temporary staging when backing up many small files.
- Parallelism: increase worker threads for large environments but monitor CPU/memory usage.
- Network: use bandwidth throttling during business hours; enable multipart uploads for cloud backends.
- Database backups: use native snapshotting when available (LVM, ZFS, cloud provider snapshots) to avoid long lock times.
Monitoring & Alerts
- Monitor job success rates, data change rates, and storage consumption.
- Configure alerts for failed jobs, low storage, or exceeded retention thresholds.
- Integrate with monitoring systems (Prometheus, Nagios) via metrics endpoint or webhooks.
Troubleshooting Common Issues
- Failed upload: check network connectivity, credentials, and endpoint TLS settings.
- Slow backups: inspect CPU/RAM, I/O wait, and parallel worker settings; consider increasing staging throughput.
- Restore failures: verify backup integrity, check encryption key availability, ensure correct restore permissions.
- Agent connection problems: firewall rules, outdated agent version, clock skew.
Example Backup Job (CLI)
ps-backup job create --name "DailyFiles" --paths "/home,/etc" --target "s3://backups-bucket/daily" --type incremental --schedule "0 2 * * *" --retention "daily=7,weekly=4,monthly=12" --encrypt --compression lz4 Compliance & Data Governance
- Configure retention to meet legal/regulatory requirements.
- Maintain tamper-evident logs and WORM (Write Once Read Many) storage if required.
- Use encryption and key management practices compliant with standards (NIST, GDPR considerations for data locality).
Best Practices Summary
- Use a mix of full and incremental backups for efficiency.
- Store at least one copy offsite (different geographic region).
- Encrypt client-side and manage keys securely.
- Test restores regularly and document recovery procedures.
- Monitor storage growth and automate lifecycle policies.
