What is a disk quota?
Disco quota is a protocol that system administrators often use to ensure that available sources are fairly and reasonably divided among users of operating systems that are used by the domestic or business network. This setting of the file use of each workstation system in the network helps to prevent multiple resources from using one user at the expense of another user in the group. The system manager usually has the ability to assign disk quotas based on workstations and to each user.
There are basically two recognized types of quota implementation on the disk that are used today. The first is known as a block quota or use. With this system's approach, the system administrator sets the limits of the disk space that any system user can use. By setting a quota of use, the administrator can ensure that all network users have adequate access to resources needed to perform the basic tzepit, but do not use so many resources that other users remain reducedreserves.
The second way to manage the function of disk quotas is known as a quota of inode or file. This approach to disk quota management focuses on limiting the total number of directories or files that can be created rather than dealing with the amount of disk space. One of the advantages of this approach is that it can reduce the creation of multiple files or directories that are so similar to nature and content that they should be included in one file or directory in the first place.
Most administrators use some type of notification or warning when a user is about to exceed its current disk quota. This is often referred to as a soft quota and uses a simple announcement that the user is approaching their limit. However, this approach does not include any subsequent action, except for the administrator warning that the user is close to their assigned disc quota.
more aggressiveThe announcement, known as a hard quota, performs a process around a simple warning. After notifying the user that he is approaching his assigned disc quota, the system will effectively close after exceeding the assigned quota. This type of system management will require the administrator to intervene, either by increasing the disk quota assigned to the user or working with the user to the archive or removing unnecessary files and reducing the user's files back to the level below the quota.
