How can you test the reliability of your GIS backup?

由人工智能和领英社区提供技术支持

A GIS backup is a copy of your geographic data and related files that can be used to restore your system in case of a disaster, such as a hardware failure, a virus attack, or a human error. Having a reliable GIS backup is essential to protect your valuable information and ensure business continuity. But how can you test the reliability of your GIS backup and make sure it works when you need it? Here are some tips to help you verify your GIS backup strategy and avoid unpleasant surprises.

1 Plan your backup tests

The first step to test the reliability of your GIS backup is to plan your backup tests in advance. You should define the frequency, scope, and objectives of your tests, as well as the roles and responsibilities of the staff involved. You should also document your backup procedures, policies, and standards, and review them regularly. A good backup plan should include both scheduled and random tests, as well as different types of backup scenarios, such as full, incremental, or differential backups.

Incorporating GIS backup testing into existing emergency exercises, like fire drills or security protocols, provides a more integrated approach to preparedness. This not only heightens the realism of the training but also ensures that staff roles and responses are tested under conditions that closely simulate actual emergencies, thereby solidifying readiness posture.

2 Perform your backup tests

The second step to test the reliability of your GIS backup is to perform your backup tests according to your plan. You should use a separate test environment that mimics your production environment as closely as possible, and avoid testing on live data or systems. You should also use the same backup software, hardware, and media that you use for your actual backups, and follow the same steps and protocols. You should test both the backup and the restore processes, and check for any errors, warnings, or inconsistencies in the logs, reports, or messages.

Many companies do restore tests once a year. Some test once a quarter. Since many things can go wrong with backups, the more often you can perform test restores, the better. A successful test restore in the past is no guarantee that your backups are successful now, especially with hackers breaking in and shutting down your backups. Administrators take risks when they test infrequently. Our service actually does test restores daily to ensure the best possible odds of a recovery in case of disaster.

3 Evaluate your backup results

The third step to test the reliability of your GIS backup is to evaluate your backup results and measure their effectiveness. You should compare the backup data with the original data, and verify that they are identical, complete, and accurate. You should also check the backup speed, size, and compression, and ensure that they meet your expectations and requirements. You should also assess the restore time, performance, and quality, and make sure that they do not affect your normal operations or user experience.

4 Report your backup findings

The fourth step to test the reliability of your GIS backup is to report your backup findings and share them with your stakeholders. You should document your test methods, outcomes, and recommendations, and use clear and concise language and formats. You should also highlight any issues, risks, or gaps that you identified during your tests, and propose solutions or improvements to address them. You should also communicate your backup successes and best practices, and acknowledge the contributions of your team members.

5 Update your backup plan

The fifth step to test the reliability of your GIS backup is to update your backup plan based on your test results and feedback. You should review your backup objectives, criteria, and schedule, and make any necessary changes or adjustments. You should also update your backup procedures, policies, and standards, and ensure that they reflect the current state and needs of your system. You should also train your staff on the new or modified backup processes, and monitor their compliance and performance.

6 Repeat your backup tests

The sixth and final step to test the reliability of your GIS backup is to repeat your backup tests periodically and consistently. You should not assume that your backup is reliable just because it worked once or twice. You should test your backup regularly and systematically, and adapt to any changes or challenges that may arise in your system, data, or environment. You should also keep track of your backup history, trends, and patterns, and use them to improve your backup strategy and quality.

Prepare a “bare metal” rebuild If you lost your all of your kit due to flooding/theft etc and had to do a complete rebuild from first principles on new kit, how long would a complete rebuild take including the OS, patches, software environment and databases and web server
