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).
