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\&. .SH "OPTIONS" .PP \-h .RS 4 Get help information\&. .RE .PP \-s suffix .RS 4 The \FC\-s\F[] 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\&. .RE .PP \-v .RS 4 The \FC\-v\F[] will check the database for damages (currupt data) which if detected causes the backup to be restored\&. .RE .SH "COMMANDS" .PP \fIGENERAL INFORMATION\fR .PP The \FCtdbbackup\F[] 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 .PP Samba \&.tdb files are stored in various locations, be sure to run backup all \&.tdb file on the system\&. Important files includes: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \FCsecrets\&.tdb\F[] \- usual location is in the /usr/local/samba/private directory, or on some systems in /etc/samba\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \FCpassdb\&.tdb\F[] \- usual location is in the /usr/local/samba/private directory, or on some systems in /etc/samba\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \FC*\&.tdb\F[] located in the /usr/local/samba/var directory or on some systems in the /var/cache or /var/lib/samba directories\&. .SH "VERSION" .PP This man page is correct for version 3\&.0 of the Samba suite\&. .SH "AUTHOR" .PP 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\&. .PP The tdbbackup man page was written by John H Terpstra\&.
