  81         The <command>ntdbbackup</command> utility can safely be run at any time. It was designed so
  82         that it can be used at any time to validate the integrity of ntdb files, even during Samba
  83         operation. Typical usage for the command will be:
  84         </para>
  85
  86         <para>ntdbbackup [-s suffix] *.ntdb</para>
  87
  88         <para>
  89         Before restarting samba the following command may be run to validate .ntdb files:

  91
  92         <para>ntdbbackup -v [-s suffix] *.ntdb</para>
  93
  94         <para>
  95         Note that Samba 4 can use .tdb files instead, so you should
  96         use <command>tdbbackup</command> on those files.
