Hanna Backup Procedures

Hanna Backup Procedures

This document provides comprehensive guidelines on how to perform backups for Hanna, the puppet used in our projects. The purpose of these procedures is to ensure data integrity, facilitate disaster recovery, and maintain operational continuity.

Introduction

Hanna, as an essential part of our operations, requires reliable backup procedures to safeguard all relevant data, configurations, and scripts associated with its operation. This document outlines the step-by-step process for backing up Hanna's data, along with best practices and troubleshooting tips.

Scope

These procedures cover:

• Data files related to Hanna
• Configuration files
• Scripts and automation tools
• Relevant documentation and logs

Note: These backups are to be performed separately from the main Hanna repository to prevent bundling and to ensure modular recovery.

Backup Frequency

• Daily incremental backups: To capture recent changes.
• Weekly full backups: To create comprehensive restore points.
• Monthly archival backups: For long-term storage.

The backup schedule should be aligned with operational needs and data change frequency.

Backup Methods

Automated Scripts

Use automated scripts to perform backups at scheduled intervals. Scripts should be configured to:

• Copy relevant files to a dedicated backup location.
• Compress files for storage efficiency.
• Log backup activities and errors.

Manual Backups

Manual backups can be performed when necessary, especially before major updates or changes. Ensure to:

• Copy all relevant files to a secure backup location.
• Verify the integrity of backups.

Backup Storage

• Use secure, redundant storage solutions such as network-attached storage (NAS), cloud storage, or external drives.
• Ensure backup data is encrypted to prevent unauthorized access.
• Maintain backup copies in multiple locations if possible.

Restoration Procedures

In case of data loss, follow these steps to restore Hanna:

1. Identify the most recent valid backup.
2. Verify backup integrity.
3. Follow the restoration process specific to the backup method used.
4. Test Hanna after restoration to confirm data accuracy.

Troubleshooting

• Check script logs for errors.
• Ensure sufficient storage space.
• Verify network connectivity if backups are stored remotely.
• Consult backup logs regularly to detect issues early.

Best Practices

• Regularly test backups by restoring data in a test environment.
• Keep multiple backup versions.
• Document all backup activities.
• Update backup procedures after any significant changes.
