NTDBBACKUP(8) System Administration tools NTDBBACKUP(8)NAME
ntdbbackup - tool for backing up and for validating the integrity of
samba .ntdb files
SYNOPSIS
ntdbbackup [-s suffix] [-v] [-h]
DESCRIPTION
This tool is part of the samba(1) suite.
ntdbbackup is a tool that may be used to backup samba .ntdb files. This
tool may also be used to verify the integrity of the .ntdb 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.
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 ntdb 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.
COMMANDS
GENERAL INFORMATION
The ntdbbackup 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 ntdb
files, even during Samba operation. Typical usage for the command will
be:
ntdbbackup [-s suffix] *.ntdb
Before restarting samba the following command may be run to validate
.ntdb files:
ntdbbackup -v [-s suffix] *.ntdb
Note that Samba 4 can use .tdb files instead, so you should use
tdbbackup on those files.
Samba .tdb and .ntdb files are stored in various locations, be sure to
run backup all .(n)tdb files on the system. Important files includes:
· secrets.(n)tdb - usual location is in the /usr/local/samba/private
directory, or on some systems in /etc/samba.
· passdb.(n)tdb - usual location is in the /usr/local/samba/private
directory, or on some systems in /etc/samba.
· *.tdb and *.ntdb located in the /usr/local/samba/var directory or
on some systems in the /var/cache or /var/lib/samba directories.

The original Samba software and related utilities were created by
Andrew Tridgell. Samba is now developed by the Samba Team as an Open
Source project similar to the way the Linux kernel is developed.
The ntdbbackup man page was written by Rusty Russell, based on the
tdbbackup man page by John H Terpstra.
