is a tool that may be used to backup samba \&.tdb files\&. This tool may also be used to verify the integrity of the \&.tdb files prior to samba startup or during normal operation\&. If it finds file damage and it finds a prior backup the backup file will be restored\&.
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\&.
will check the database for damages (corrupt data) which if detected causes the backup to be restored\&.

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\&.
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:
.PP
tdbbackup [\-s suffix] *\&.tdb
.PP
Before restarting samba the following command may be run to validate \&.tdb files:
.PP
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:
