title: Backup a sqlite3 database
body: <p>I have a Python project where I use sqlite3 to save data.</p>
  <p>I want to do a backup of the database ( I am really worried about datalock, cause my software will be used by like 10 peoples which will have to access to my database to write or read, and without luck, someone will try to access to the database at the bad moment, even if I will increase timeout)</p>
  <p>If I do it manually with the Windows cmd, there is no problem.</p>
  <pre><code>v:
  cd V:\directory\
  sqlite3 mydatabase.db&quot;
  .backup backup_db.db
  </code></pre>
  <p>I try to do a batch file which will be call every hours by my python software to do it automatically.
  I applied the same commands in it.</p>
  <p>The batch file is launched, but the process stop after the opening of the database.
  The dot command is not executed.</p>
  <p>Where is my mistake?</p>
