E-Mail for each mysql-backup cronjob run

[mibuthu]

I get an email every day with the result of the mysql backup cronjob run:

==> Backup completed successfully.
==> Detailed log (/var/vmail/backup/mysql/2021/12/14/2021-12-14-03-40-01.log):

* Backup completed (Success? YES).

I my opinion there should be no email if the script completes successfully, so the script should have no output in this case.
As the actual script output is reasonable for manual runs, probably adding a '-q' (quiet) arg to the backup_mysql.sh script would be the best solution.
