Commands
GENERALINFORMATION
The tdbbackup utility can safely be run at any time. It was designed so that it can be used at any time
to validate the integrity of tdb files, even during Samba operation. Typical usage for the command will
be:
tdbbackup [-s suffix] *.tdb
Before restarting samba the following command may be run to validate .tdb files:
tdbbackup -v [-s suffix] *.tdb
Samba .tdb files are stored in various locations, be sure to run backup all .tdb file on the system.
Important files includes:
• secrets.tdb - usual location is in the /usr/local/samba/private directory, or on some systems in
/etc/samba.
• passdb.tdb - usual location is in the /usr/local/samba/private directory, or on some systems in
/etc/samba.
• *.tdb located in the /usr/local/samba/var directory or on some systems in the /var/cache or
/var/lib/samba directories.
Description

Name
tdbbackup - tool for backing up and for validating the integrity of samba .tdb files
Options
-h
Get help information.
-s suffix
The -s option allows the administrator to specify a file backup extension. This way it is possible to
keep a history of tdb backup files by using a new suffix for each backup.
-v
The -v will check the database for damages (corrupt data) which if detected causes the backup to be
restored.
-n hashsize
The -n option sets the hash size for the new backup tdb.
-l
This options disables any locking, by passing TDB_NOLOCK to tdb_open_ex(). Only use this for database
files which are not used by any other process! And also only if it is otherwise not possible to open
the database, e.g. databases which were created with mutex locking.
