Main Points about Disk Quotas
Disk space can be restricted by implementing disk quotas.
It alert a system administrator before a user consumes too much disk space or a partition becomes full.
Disk quotas can be configured for individual users as well as user groups.
In addition, quotas can be set not just to control the number of disk blocks consumed but to control the number of inodes.
Because inodes are used to contain file-related information, this allows control over the number of files that can be created.
