Disk space

The amount disk space required for a Magnolia instance depends on what data you store and how many versions of content you keep. Today, marketing oriented websites use a lot of images and video. It is not uncommon for such a website to have 5-10 GB of Web content.

Best practice

We recommend that you allocate at least 50GB of disk space for an author instance and 25GB for a public instance.

Example calculation

What takes space? GB

Total website content including assets such as images and videos.


Magnolia and Tomcat systems.


Cached content, assuming cache is 70% full.


Site is served in two languages. The other language is also cached.


Content is indexed for search. A compressed index is 20% of the original data size.


Logs: access, audit, error


Temporary storage for streaming large files


Total for a public instance


Versioning on author instance, assuming 30% of content is versioned 20 times.


Total for an author instance


Adjust the numbers to your needs.

  • Is your site smaller?

  • Is your database on the same machine as the application server? You can also persist data to a remote database.

  • Have you switched off versioning?

There are many options for reducing the space required. However, assume that you need up to 50 GB of space out of the box.
