+ <para>
+<indexterm><primary>tdb file locations</primary></indexterm>
+ The directory in which Samba stores the tdb files is determined by compile-time directives. Samba-3 stores
+ tdb files in two locations. The best way to determine these locations is to execute the following
+ command:
+<screen>
+&rootprompt; smbd -b | grep PRIVATE_DIR
+ PRIVATE_DIR: /etc/samba/private
+</screen>
+ This means that the confidential tdb files are stored in the <filename>/etc/samba/private</filename>
+ directory. Samba-3 also uses a number of tdb files that contain more mundane data. The location of
+ these files can be found by executing:
+<screen>
+&rootprompt; smbd -b | grep LOCKDIR
+ LOCKDIR: /var/lib/samba
+</screen>
+ Therefore the remaining control files will, in the example shown, be stored in the
+ <filename>/var/lib/samba</filename> directory.

+ The persistent tdb files are described in <link linkend="tdbpermfiledesc">the Persistent TDB File

+ preserved during machine migrations, updates and upgrades.

+ The temporary tdb files do not need to be backed up, nor do they need to be preseved across machine
