YouTrack uses its own in-process database, no dedicated database server is required.
note
Accessibility
Please ensure that database files are accessible from within YouTrack! The user account that runs the YouTrack service should always have sufficient permissions to create, modify and read database files. Access to database files via network is prohibited since YouTrack in that way cannot guarantee durability of your data.
Each backup file contains a snapshot of your database including all of the attachments that are stored on your server at the time the file was created.
A collection of valid backup files can come in handy if you need to restore your installation after an outage or attack. We strongly recommend that you enable regular backup of your YouTrack database and set up notifications should the backup fail.
