By default, Confluence stores attachments in the home directory (e.g. in a file system).

If your team has large or increasing data sets and requires the ability to scale efficiently, we recommend you use S3 object storage. Amazon S3 is currently the only Confluence-supported object storage solution.

Good to know:

  • Amazon S3 object storage is an optional attachment storage method available to anyone on a Data Center license and running Confluence in AWS.
  • If you're a new customer, see S3 object storage for setup instructions.
  • If you're an existing customer, you'll need to migrate your attachment data to S3 object storage from the file system or another storage method. See Attachment storage configuration for steps to do this.
  • Even if you use S3 object storage, other non-attachment data will still be stored in your home directory.
