If you have installed your web application (such as WordPress, OpenCart, Joomla etc) on one of our Shared Hosting services using the Installatron Applications Installer, the system will automatically take backups of your web application for you. From time to time you may receive an email notification from the system that the backup has failed.
The most common reason that the backups would fail is that your hosting account has reached it disk quota limit, and there isn’t enough space to create the new backup. In this case, the error email that the system sends you may contain these errors:
- Error: Compression failed.
- Technical error: [0] No disk space available.
There are two actions that you should take if you receive these notifications:
1) Check the backup retention settings
The system can be configured to automatically maintain the backups for you, to ensure that that don’t keep adding up and take all of your space. To check this, log into your cPanel account, click on your web application (under Web Applications) and then click edit.
Scroll down, and the last section of the settings will be for Automatic Backup. This setting controls how many backups the system will maintain for you (and remove older backups that are outside of the policy). We recommend that you select the option for 1 Weekly + 1 monthly.
Once you have made your selection, click Save All. The system will remove unnecessary backups during the next maintenance run (typically overnight).
2) Check your account disk usage
You can quickly and easily check to see what is using the disk space within your account. Simply log into your cPanel account, and clock on the 'Disk Usage' application. The page may take a few seconds to load while it looks at all the data in your account, but will then present an easy to read graph showing where your disk space is being used. Common culprits for high disk space usage include:
- Lots of emails stored on the server. If this is the case, consider archiving or removing old emails
- Old backups
- Bloated databases
From this page you can also drill down into the file/folder structure of your account to find where disk usage may be higher than expected.
