AKS restore DevOps Test Hub

Learn reliable methods for AKS restore DevOps test hub to ensure quick recovery. Our DevOps Support team is ready to assist you. 

Restoring DevOps Test Hub Data on Azure Kubernetes Service

Safeguarding test data is one of the most important tasks in any DevOps workflow. When HCL DevOps Test Hub runs on Azure Kubernetes Service (AKS), a reliable backup and restore strategy ensures that projects remain accessible, downtime stays minimal, and recovery is quick after unexpected issues. This guide explains why data protection matters, how to back up and restore Test Hub on both AKS and Ubuntu, and the best practices that keep disaster recovery smooth and predictable.

Why Backups and Restores Matter for DevOps Test Hub

Every DevOps environment depends on accurate and accessible data. Without a backup, even minor errors can disrupt teams and delay releases.

Key benefits of backups and restores

• Backups maintain business continuity when failures occur.
• Restores make it possible to recover quickly from crashes, corruption, or security incidents.
• Rollback options during upgrades or migrations prevent unexpected disruptions.
• Consistent test environments can be created for accurate debugging and validation.
• Compliance and audit requirements are easier to meet with a reliable backup system.
• Protection against accidental deletion or human mistakes ensures stability.

Risks of skipping a backup strategy

• Permanent loss of critical project data.
• Downtime that halts testing pipelines and delays releases.
• Costly disruptions that impact revenue and operations.
• Reputational damage and loss of customer trust.
• Exposure to ransomware and security breaches.
• Non-compliance penalties from regulatory authorities.

Backing Up DevOps Test Hub Data on AKS and Ubuntu

The method you choose depends on whether Test Hub runs on AKS or directly on Ubuntu servers.

Backup on AKS
Azure Backup provides an integrated way to protect AKS clusters.

Requirements:

• A Backup vault in the same region and subscription as the cluster.
• Registered Kubernetes configuration provider.
• Backup extension installed on the cluster.
• Secure connection between the vault and the AKS environment.

Process:

1. Define a backup policy with schedules and retention rules.
2. Select the data source, such as namespaces or labels.
3. Run scheduled or on-demand backups through the Azure portal or CLI.

Backup on Ubuntu
When Test Hub is installed on Ubuntu, use traditional database and file backups. For environments where teams frequently experiment with containerized deployments, it is also useful to install Kubernetes on Ubuntu 22.04 on a single node to manage local clusters efficiently before scaling to production.

Database backup example:

pg_dump -U <username> -h <hostname> -p <port> <database_name> > /path/to/backup/db_backup.sql

File system backup example:

tar -czvf /path/to/backup/files_backup.tar.gz /opt/HCL/DevOpsTestHub/

This approach protects both configuration files and stored data. Automating these backups ensures consistency and reduces manual errors.

Key considerations for backups

• Store copies offsite in Azure Blob or another secure location.
• Test backups regularly to confirm that it restores work.
• Automate scheduling to prevent gaps.
• Set up alerts to track backup status and failures.

Restoring DevOps Test Hub Data with Velero on AKS and Ubuntu

When recovery is necessary, a clear restoration process prevents delays.

Restore on AKS using Velero

1. Log in to the cluster:

az login

2. Start the restore process:

velero restore create --from-backup <BACKUP_NAME>

3. Check progress and confirm completion:

velero restore describe <RESTORE_NAME> --details

4. If external databases are used, restore them separately.
5. Restart the required services to complete recovery.

Restore on Ubuntu

1. Stop the cluster:

k3s-killall.sh

2. Restore the data:

sudo ./backup.sh restore [options] <backup-file-name>

3. Adjust namespaces or release names if needed.
4. Restart the cluster and services:

sudo systemctl start k3s

What to check after restoration

• Verify that the user has correct permissions.
• Confirm that the restored data matches the intended state.
• Check logs and validate that backups were not corrupted.

Disaster Recovery Best Practices

Disaster recovery extends beyond backups. A structured plan reduces risks and ensures fast recovery after failures.

Essential practices

• Define clear Recovery Time and Recovery Point Objectives.
• Follow the 3-2-1 backup rule: three copies, two media types, one offsite.
• Use immutable storage and strong encryption.
• Automate both backups and validation tests.
• Run recovery drills regularly and update the plan after infrastructure changes.
• Keep documentation clear so that recovery steps are easy to follow.

Troubleshooting common recovery failures

Many failures happen because of poor planning. Common issues include:

• Outdated recovery plans that do not reflect current systems.
• Backups that were never tested and fail during emergencies.
• Local-only backups that cannot survive natural disasters.
• Recovery objectives that are unrealistic for business needs.
• Communication gaps during outages.
• Ransomware attacks that compromise unprotected backups.
• Failed upgrades without rollback options.
• Inefficient storage management and unnecessary backup sprawl.
• Over reliance on third-party providers without proper contingency plans.
