High I/o Of Database Backup

My hosting allows 10 mb/s I/O limit which is quite high for a shared hosting. However they are penalizing me for hitting the limit whenever I perform a database backup via Cscart Admin panel. I know I can perform backups using cpanel as an alternate solution. But does anyone know if I can configure cs-cart not to exceed 10 mb/s?

using 4.3.2
