How to Check & Fix Disk Over Quota Issues in DirectAdmin
This guide explains how to check disk usage in DirectAdmin and fix “Disk Quota Exceeded” problems. If your hosting account is full, your website, email, backups, or uploads may stop working correctly.
Common Signs of Disk Quota Issues
Email Not Receiving
Mailboxes may stop receiving messages when storage limits are reached.
Website Errors
Your website may fail to upload files, generate backups, or cache content.
Backup Failures
Backups may fail if there is not enough free disk space available.
Step-by-Step Instructions
Step 1: Login to DirectAdmin
Access your hosting account and open DirectAdmin.
Step 2: Open System Info & Files
Navigate to the System Info & Files section inside DirectAdmin.
Step 3: Open User Statistics
Click on User Statistics to view account usage and storage information.
Step 4: Review Disk Usage
Review the Disk Usage section to identify which folders are using the most storage space.
Common large folders include:
- mail/
- domains/
- backups/
- tmp/
- public_html/
Expand folders to drill deeper into directories using the most space.
Folder sizes are displayed in MB or GB, making it easy to identify large directories.
Step 5: Remove Unneeded Files
Delete unnecessary backups, spam emails, cache files, logs, or large archives that are no longer required.
Important
Be careful not to delete important website files, databases, or active email accounts. Always keep a recent backup before removing files.
Most Common Causes of Disk Quota Problems
Spam & Junk Email
The most common cause of disk quota issues is large amounts of spam or junk email stored inside mailboxes.
Check:
- Spam folders
- Trash folders
- Sent mail
- Large attachments
Emptying these folders can quickly free significant disk space.
WordPress Backup Plugins
WordPress backup plugins commonly store multiple full website backups inside your hosting account.
Common examples:
- UpdraftPlus
- All-in-One WP Migration
- Duplicator
- BackupBuddy
Backup files are often stored inside:
/domains/yourdomain.com/public_html/wp-content/
Old backups can sometimes use several GB of storage space.
Cache & Log Files
Cache plugins and log files can grow over time and consume unnecessary storage.
Examples:
- LiteSpeed Cache
- WP Rocket
- Wordfence logs
- Error logs
Cache files are usually safe to clear from the plugin settings.
How to Identify Large Folders
Expand Folder Paths
Expand folder paths inside Disk Usage to drill deeper into subfolders.
Check Folder Sizes
DirectAdmin displays folder sizes in MB or GB, helping identify which directories are using the most storage.
Follow the Largest Folders
Continue expanding the folders using the highest storage until you identify the files or folders using the most space.
Example
domains/
└── yourdomain.com/
└── public_html/
└── wp-content/
└── updraft/
└── backup-files.zip
If a folder shows several GB of usage, old backups or log files may need removing.
Common Issues & Fixes
Disk Usage Not Updating
Refresh DirectAdmin or wait a few minutes for usage statistics to update.
Email Still Bouncing
Empty Spam and Trash folders fully inside webmail after deleting emails.
Cannot Delete Files
Use File Manager if FTP cannot remove large files or folders.
Pro Tips
Download Backups Locally
Store backups on your computer or remote cloud storage instead of inside your hosting account.
Clear Spam Regularly
Regularly empty spam and trash folders to prevent mailboxes filling up.
Monitor Usage Monthly
Regular checks can help prevent future disk quota problems before they cause downtime.
