I would like to have a queue for creating backups. For instance, when clicking on create full backup in cpanel, it would queue the request and check to see if any other backups were running and then proceed. This would prevent a reseller or someone to spawn 10+ backups at one time. Also, an option in whm to select how many concurrent backups are allowed to run.
