Google Cloud Platform: Backup & Disaster Recovery
This technical guide provides a step-by-step process for creating a backup and disaster recovery plan in Google Cloud Platform. The guide covers the creation of a Google Cloud Storage bucket for storing backups, the configuration of a backup schedule, the creation of a backup script that uses the Google Cloud Storage API, the testing of the backup script, the creation of a disaster recovery plan, the testing of the disaster recovery plan, the monitoring of backups for errors or issues, the monitoring of storage usage and cost, and the regular updating of the backup and disaster recovery plan
Step 1: Create a Google Cloud Storage bucket for storing backups:
- Open the Google Cloud Console and navigate to the Storage section.
- Click on the "Create Bucket" button.
- Enter a unique name for the bucket and select a storage class and location.
- Configure any additional settings as desired (e.g. object lifecycle management, encryption, etc.).
- Click "Create" to create the bucket.
Step 2: Set up a backup schedule:
- Open the Google Cloud Scheduler and create a new job.
- Enter the desired schedule for the job (e.g. daily at 1:00 AM) and select the appropriate time zone.
- Specify the command to be run (e.g. the backup script) and any required parameters.
- Click "Create" to create the job.
Step 3: Create a backup script:
- Write a script that uses the Google Cloud Storage API to upload data to the designated bucket.
- The script should be configured to upload specific data (e.g. a specific database or file system) to the bucket.
- Test the script to ensure that it is working properly and that all necessary data is being backed up.
Step 4: Test the backup script:
- Run the backup script manually to ensure that it is working as expected and that all necessary data is being backed up.
- Check the bucket in the Google Cloud Console to confirm that the data has been uploaded.
Step 5: Create a disaster recovery plan:
- Outline the steps to be taken in the event of a disaster, including how to restore data from backups and how to access backups in the event that the primary data center is unavailable.
- Identify key personnel and assign roles and responsibilities.
- Test the plan regularly to ensure that it is up to date and that all necessary data can be quickly and easily restored in the event of a disaster.
Step 6: Test the disaster recovery plan:
- Simulate a disaster scenario and practice restoring data from backups to ensure that the process is working as expected.
- Make any necessary updates or revisions to the plan based on the results of the test.
Step 7: Monitor the backups:
- Monitor the backups for any errors or issues, and troubleshoot as needed.
- Ensure that all backups are being performed on schedule and that the data is being stored in the correct location.
Step 8: Monitor storage usage and cost:
- Monitor the storage usage and cost of the backups, and archive or delete older backups to save space as needed.
- regularly review the storage class, encryption and object lifecycle management settings to ensure they are still optimised for the backup data and cost.
Step 9: Keep the plan updated:
- Keep the backup and disaster recovery plan updated with any changes or updates to the environment, such as new data sources, new personnel, changes in recovery time objectives, etc.
- Review the backup and disaster recovery plan at least annually and after significant changes to the environment.
