How To Take An Adminer Database Backup

Website backups are essential for preserving your valuable data and Adminer is a tool to backup your database. 

Databases hold crucial information such as user data and site content, making them vital for any website’s functionality. Adminer is a basic interface to manage all your database tables. It’s manual in nature and can be prone to failure. 

In this article, we’ll go over the steps to taking and restoring a backup. We’ll break down the steps and make it simple for you. 

TL;DR: Adminer backups are easy but susceptible to human error and failure. This is because it’s a type of manual backup that requires human intervention. Use BlogVault instead for more reliable and automated database backups.

Taking Adminer database backup

Adminer is a handy tool for backing up databases, and stands out because of its lightweight nature. It’s a good alternative to cPanel database backups and is accessible through any web browser. It supports various databases like MySQL and PostgreSQL. The simple interface makes it easy to navigate and here are the steps:

Export database tables

1. Launch Adminer and click on the Export option located on the left-side panel.
2. Decide which database tables you want to back up. We recommend selecting all tables to ensure a complete backup.

3. Choose the output and format for your backup file. We recommend using gzip for compression and SQL for format to maintain efficiency.
4. Once you have made the selections, click the Export button. 

This will export your database file to your device. Ensure you save copies of this file in multiple safe locations to protect against data loss.

Restore Adminer backup

Restoring your database with Adminer is just as straightforward as backing it up. You just need to import a previously saved database file to restore your site’s data. Here’s a step-by-step guide on how to do this using Adminer’s in-built feature.

1. Access Adminer and choose the database into which you want to import your data.
2. Click on the Import button to initiate the restoration process.
3. Select the file you want to import. This is typically an SQL file that contains your backup data.
4. Decide on the import options you’ll need, such as Structure and Data, to ensure the correct parts of the database are restored.

5. Click the Execute button to begin the import process. This will restore the database data from your backup file.
6. Wait for the import process to complete and check for any error messages to ensure the restoration is successful.

Troubleshooting Adminer database backup

Just like a cPanel backup, you might encounter a few issues with an Adminer backup. These problems can be frustrating, but they usually have straightforward solutions. We’ve outlined common symptoms below that you might experience and how to address them effectively.

• Backup failures: If your backup attempts fail, it could be due to insufficient disk space or incorrect file permissions. Ensure there is enough space on your drive and verify that Adminer has the correct permissions to access and save the files.
• Slow backup process: A sluggish backup can indicate that your database needs optimization. Before starting a backup, optimize your database by removing unnecessary data and reindexing tables, which can improve efficiency.
• Timeout errors: These errors are caused by your operation taking longer than PHP’s maximum execution time allows. To fix this, increase the maximum execution time in your PHP settings to accommodate longer processes.
• SQL errors during backup: These errors are often caused by syntax issues or conflicting queries in your database. Review your SQL statements for mistakes, or check for queries that might conflict with each other.
• Incomplete backups: If backups are not complete, you might not have all tables and data selected. Double-check to ensure that all necessary components of your database are included in the backup.
• Memory limit issues: These occur when backing up large databases exceeds the PHP memory limit. In such cases, increase the PHP memory limit within your server settings to handle the size of your database.
• File saving problems: If files are not saving correctly, it could be due to an incorrect path or a lack of permissions. Verify that the path is correct and that all necessary permissions are granted.
• Backup format issues: These issues arise when you select an incorrect format to restore. Confirm that the format you’re using is compatible with both your database setup and your intended use.
• Version compatibility: If you encounter persistent backup failures, it might be due to version incompatibilities between Adminer or your PHP installation. Keeping both up to date can resolve many compatibility issues.

Should you use Adminer to take a backup?

Using Adminer for database backups has several drawbacks, making it less than ideal for this task. Here are the main reasons why it may not be the best choice:

• Resource intensive when your backup frequency is high
• Requires manual intervention for every backup, leading to potential human error.
• Lacks built-in scheduling for automatic or regular backups.
• Exporting large databases can be slow and may cause browser timeout or memory issues.
• Potential security risks if the tool is not frequently updated.
• Compatibility issues might arise with certain PHP versions, leading to operational challenges.
• Only one kind of backup – partial backups
