tdbbackup [-s suffix] [-v] [-h]
This tool is part of the samba(1) suite.

The -s option allows the adminisistrator 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.
The -v will check the database for damages (currupt data) which if detected causes the backup to be restored.
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
