Last Updated: September 9, 2022

Latest News: Updated the documentation.

It is very important to create a database backup of your site. AIOWPS has the feature needed for this. Once you install AIOWPS plugin, the first step you need to take is to create a database backup. If anything goes wrong from here on, you will be protected and you will be able to restore your site through the database you create in this step.

Note: Make sure you follow these steps carefully.

 What you need:

Step 1 ) Go to WP Security -> Database Security admin sidebar as illustrated in the image below to start configuring your database backups and administration.

Database prefix

Important: Create a database backup before you begin changing your database prefix. This is an extremely important step you must take just in case something goes wrong.

Step 2 ) Go to WP Security -> Database Security -> Database Prefix tab to set up the following options.

Note: The following warning, lets you know that the database prefix should be changed. This is very important.

Your site is currently using the default WordPress DB prefix value of “wp_”. To increase your site’s security you should consider changing the DB prefix value to another value.

DB Prefix Options Settings

  • Current database table prefix:
  • Generate new database table prefix:
  • Or choose your own DB prefix by specifying a string which contains letters and/or numbers and/or underscores. Example: xyz_.
  • Click on Change database prefix button once you have completed configuring this settings.

Enabling this feature will give you another  10 points score towards your security meter. See images below. (Intermediate Security Level)

Troubleshooting Backups

Q1 I have created scheduled backups, but they don’t run consecutively on a daily basis as per my setup.  I don’t understand how backup works using WordPress wp-cron functionality.

Explanation: How the scheduled backup feature works with WordPress wp-cron functionality.

The backup time is set at the time you save the automatic scheduled backup settings. In order for the backup to trigger around the time you expect it to, you will need some kind of site activity (such as someone visiting) just after that time.

For example: I’ve configured my scheduled backup settings to do a once daily backup. I saved the config now and it is currently 7:11pm at my location. Then the wp-cron job will be scheduled to perform a backup at around 7:11pm everyday. What this means is that the next backup will be scheduled for tomorrow at approximately 7:11pm. However, if nobody visits my site till 10:30pm tomorrow, then no backup will occur at 7:11pm because there was no activity on the site just after 7:11pm to trigger the wp-cron event. What will happen is that the system will immediately trigger a backup as soon as someone visits my site anytime after the scheduled time. (In other words in this example the backup will occur at 10:30pm)

On the next day the same thing applies. The aiowps backup is still scheduled for around 7:11pm and if I get my next visitor at 7:12pm then the backup will be performed at 7:12pm.

The following example should help you understand the example mentioned above. (Explanation provided by wpsolutions)

Backup Test Steps:

1) Enable debug, go to WP Security -> Settings -> Enable Debug (The log files can help you troubleshoot backup issues.)

2) Set “Number of Backup Files To Keep” to 5.
Do 5 separate manual backups. Check the backups directory and verify that there are 5 backups.

3) Set “Number of Backup Files To Keep” to 3.
Do 2 more separate manual backups. Check the backups directory and verify that there are 3 backups only. (2 oldest backups from previously should have been deleted)

4) Set backup time interval to 1 hour.
Over a period of a day check the backup directory and verify that the number of backups is always as per the config.
(Also check the “wp-security-log-cron-job.txt” file to verify that the logs show that backups were done)

=============================

Q2 If you receive the following error message when you try to create a backup. Try one of the solutions below.

“PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 72879700 bytes) in /var/www/html/wp-content/plugins/all-in-one-wp-security-and-firewall/classes/wp-security-backup.php on line 67”

It could be related to the backup directory not being created correctly in your server when you try to create a backup. It could also mean that you need to allocate more memory to your WordPress.

Solution 1: Make sure that the following path exist in your server /yourwebsite/wp-content/aiowps_backups/. With the proper folder permissions 0755.

Solution 2: Adding the following define( 'WP_MAX_MEMORY_LIMIT', '384M' ); to wp-config.php file can also help.

Hint: Remember to make sure you have 384M allocated to your WordPress if not adjust this in accordance to what has being allocated to your WordPress. Which could be 96M, 128M, 256M.

=============================

Q3 I am unable to create database backups. How do I fix this?

Solution: Check to make sure the following folder “aiowps_backups” in the wp-content folder exist with the correct file permissions. Click the following link forum post to learn more.
