## Managing server data

During its running process, JReport Enterprise Server keeps track of server information and stores it to its own database for the purpose of running various managing and monitoring tasks, such as managing the resources on the server, monitoring the task running status, and collecting server running statistics.

The server data includes system tables and profiling tables. Each type of data is saved to its own database. The system database holds information of folders, nodes, versions, the security system, and the completed table. The profiling database holds server runtime performance related information.

JReport provides completed SQL files to create system and profiling tables for all databases supported. They reside in `<install_root>\script_files.`

This section covers the following topics:

- Initializing the database system as a non-admin database user
- Checking server data integrity
- Backing up/restoring server data
- Archiving and restoring server data
- Viewing the summary information of archive files
- Clearing unused nodes from the system database
