Storing attachments outside of the database

From Zarafa version 6 you will have the possibility to store all attachments outside of the MySQL database. The architecture change is made to get a more efficient MySQL caching system and get a smaller database.

Configuring storage method

The attachment storage can be configured in the server.cfg file via the option attachment_storage. When using the install script the default value is set to database, so the attachments are stored in the database. To store the attachment outside of the database, set this option to files and configure the attachment_path. Make sure that there is enough space on this partition or filesystem.
