NAME

6       tdbbackup - tool for backing up and for validating the integrity of
7       samba .tdb files
8

SYNOPSIS

10       tdbbackup [-s suffix] [-v] [-h] [-l]
11

DESCRIPTION

13       This tool is part of the samba(1) suite.
14
15       tdbbackup is a tool that may be used to backup samba .tdb files. This
16       tool may also be used to verify the integrity of the .tdb files prior
17       to samba startup or during normal operation. If it finds file damage
18       and it finds a prior backup the backup file will be restored.

OPTIONS

21       -h
22           Get help information.
23
24       -s suffix
25           The -s option allows the administrator to specify a file backup
26           extension. This way it is possible to keep a history of tdb backup
27           files by using a new suffix for each backup.
28
29       -v
30           The -v will check the database for damages (corrupt data) which if
31           detected causes the backup to be restored.
32
33       -l
34           This options disables any locking, by passing TDB_NOLOCK to
35           tdb_open_ex(). Only use this for database files which are not used
36           by any other process! And also only if it is otherwise not possible
37           to open the database, e.g. databases which were created with mutex
38           locking.

COMMANDS

41       GENERAL INFORMATION
42
43       The tdbbackup utility can safely be run at any time. It was designed so
44       that it can be used at any time to validate the integrity of tdb files,
45       even during Samba operation. Typical usage for the command will be:
46
47       tdbbackup [-s suffix] *.tdb
48
49       Before restarting samba the following command may be run to validate
50       .tdb files:
51
52       tdbbackup -v [-s suffix] *.tdb
53
54       Samba .tdb files are stored in various locations, be sure to run backup
55       all .tdb file on the system. Important files includes:
56
57       ·    secrets.tdb - usual location is in the /usr/local/samba/private
58           directory, or on some systems in /etc/samba.

60       ·    passdb.tdb - usual location is in the /usr/local/samba/private
61           directory, or on some systems in /etc/samba.

72       Source project similar to the way the Linux kernel is developed.
