tdbbackup — tool for backing up and for validating the integrity of samba .tdb files
tdbbackup [-s suffix] [-v] [-h]
This tool is part of the samba(1) suite.
tdbbackup 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.
Get help information.
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.
The -v will check the database for damages (corrupt data)
which if detected causes the backup to be restored.
