Where is the database folder of projeqtor, I would like to create a backup of the database...
It is not in ProjeQtOr, it is in your MySql installation.
But it is a bad idea to backup files to save a database.
Best is to get a dump, for instance with PhpMyAdmin, or with the excellent MySqlDumper (I use this one to save my database on linux as it provides a perl script very easy to CRON)
so in PhpMyAdmin, is there any backup system ?
Yes, it's possible to export a dump with phpMyAdmin.
