Disk space in H-Sphere is allocated to customers through quotas, which are set separately for user's home directory on the web server and each user mailbox and database. Quotas are obligatory plan resources and can't be disabled. Customers can't upload and store more MB than the resource quota allows (except for My/Pg SQL DBs) and will get an error message if they try to do so.
Every 24 hours a cron script scans end user's FTP home directory, all mailboxes, and DBs to summarize the disk space and make up summary disk usage for the last day. Summary readings of each daily scan are added up and divided by days elapsed from the beginning of the billing month. The resulting amount makes up user's average summary disk usage.
