MODX Cloud gives you the flexibility to run powerful websites without needing to worry much about the hosting infrastructure—but like any cloud platform, it’s important to understand how storage and usage limits work so you can manage your account efficiently and avoid overages.
This article gives you a high-level overview of the two main types of storage in MODX Cloud: Disk Usage and Vault Storage.
What's Covered in This Guide
- The difference between Disk Usage and Vault Storage
- Where you can find your usage info
- Links to more detailed docs
- Tips to stay within your plan limits
Disk Usage (Active Site Storage)
Disk Usage is the active storage used by your running Cloud instances. This includes:
- Website files (
www/folder contents) - PHP and nginx error logs (
/logs) - MODX-specific error logs (
/www/core/cache/logs/error.log) - Any other custom files inside your sites
It does not include: database size, Backups, Snapshots, or Archive Clouds

Vault Storage (Backups, Snapshots & Archives)
Vault Storage is used for things that aren’t actively running but are stored in your account:
- Nightly and manual backups
- Snapshots of MODX Revolution sites
- Archived Clouds (compressed site copies you can restore anytime)
These items live in secure, encrypted, and redundant object storage outside of your live environments.

Where to See Your Usage
You can view both Server Disk and Vault usage right in your account:
- Click the down arrow next to your account name (top right of the dashboard)
- Choose Account
- Click on the Add-ons Tab
- You'll see the usage beneath where it says Server Disk or Vault Storage where you’ll see a visual display of each storage type and whether you’re approaching or exceeding your plan limits.
Staying Within Limits
To help you stay within your plan’s included storage:
- Delete old logs, unused files, and media you no longer need
- Upload optimized media in modern formats such as WebP for images
- Use object storage + MODX Media Sources for large media like videos
- Archive development or dormant projects to save space
