Overview

This articles covers basic information on the different quotas in Plesk and what each quota setting means. Quotas can be useful to limit your domains use of disk space on the server thus preventing one domain from filling the server. A basic run down for the quota settings:

• Domain disk space - a calculation of everything the domain uses disk space for i.e. web, mail, databases, etc.
• Hard disk quota - a calculation of disk space used by a domains ftp user account i.e. web files.

For more detailed information, please see below.

Domain disk space

• This is how much disk space is used by the entire domain. It is made up of Plesk statistics and includes the amount of disk space taken by web pages, mail accounts, databases and other domain data including options specified in the statistic settings on Server -> Server preferences page in the Plesk CP.
• If a domain exceeds the "Domain disk space" limit, both the server administrator and the domain owner receive notifications.
• Domain disk space can be configured on the domain's limit page Domains -> example.com -> Limits -> Disk space.

Hard disk quota

• This is a file system feature that limits how much disk space can be taken by the files which are owned by a specific system account (either domain FTP user or webuser or subdomain FTP user).
• This file system quota cannot be exceeded. If the limit is reached, the system user will not be able to create new files and will receive the error "no more space left on device".
• You can set domain hard disk quota on the domain hosting setup page Domains -> example.com -> Setup -> Hard disk quota.
