# Director Services Daemon

## General

This chapter is intended to be a technical discussion of the Catalog services and as such is not targeted at end users but rather at developers and system administrators that want or need to know more of the working details of Bacula.

The Bacula Director services consist of the program that supervises all the backup and restore operations. The system administrator uses the Bacula Console to communicate to the Director daemon in order to schedule backups and to recover files. In general, the Director can perform nine major tasks (only three of which are currently implemented):

Backup
  Backup a FileSet to Backup volumes. File and Backup Volume information is stored in the Catalog.
Restore
  Restore files from Backup Volumes.
Verify
  Verify that a FileSet corresponds to what is in the Catalog or what is on the Backup Volumes. Note that not all options of Verify are currently implemented. This option makes a quite reasonable Tripwire substitute.
*Archive
  Backup a FileSet to Archived volumes and optionally remove the files from the system.
*Clone
  Make a copy of the FileSet on Cloned volumes and put the volume information in the Catalog database.
*Copy
  Make a copy of the FileSet on Copy volumes. No information on Copy volumes is stored in the Catalog database.
*Save
  Save a FileSet to Save Volumes. No information on Save volumes is stored in the Catalog database.
*Migration
  Migrate the specified FileSet to different media.
*Scan
  Restore information on the Volumes scanned to the Catalog database.
*Update
  Ensure that the files on a remote file system are updated to the specified FileSet (a sort of RDIST functionality).
