Customize Zotero toolbar to add a button that will run a backup.bat

Vialo

I've lost a lot of notes so as a security, I have created a backup.bat that automatically backup my zotero.sqlite every 10 minutes as long as Firefox is open.

But if I use firefox before working on Zotero (Firefox add-on), I often forget to run the .bat.

So I am looking for a way to personalize the toolbar to add a button that will launch the backup.bat

I want to add the button just above the note pane (cf the printscreen: http://i.imgur.com/lyjnv5I.png)

How can I add this button?

Thanks a lot for your help!

For the forum readers who may need it, here is my backup.bat (this one also launch firefox, if you don't want this step just remove the line "start %programName%" )

@echo off
set programName=firefox.exe
start %programName%
:loop
tasklist /FI "IMAGENAME eq %programName%" 2>NUL | find /I /N "%programName%">NUL
if "%ERRORLEVEL%"=="0" copy "C:\Users\Me\Zotero (online DB)\zotero.sqlite" "C:\Users\Me\Zotero_Backup_sqlite\Working_on_zotero_%date%---%time:~0,2%_%time:~3,2%_%time:~6,2%.sqlite"
if "%ERRORLEVEL%"=="1" exit /b
timeout /t 600 /nobreak
goto loop
