Disk quotas do not affect software upgrades

The so-called disk quota means that the administrator can limit the disk space that each user in the domain can use, that is, each user can only use the disk space within the maximum quota. Disk quotas monitor the usage of individual user volumes, so that each user's utilization of disk space does not affect the disk quotas of other users on the same volume. Disk quotas have the following characteristics:

Disk quotas are supported only in the NTFS file system, and disk quotas can be managed on a volume-by-volume basis. However, only the NTFS file system of Windows 2000 XP 2003 can support disk quotas, and disk quotas cannot be set on NTFS partitions of Windows NT.

Disk quotas allow you to track and control the disk usage of each user. This tracking is achieved by utilizing the ownership of a file or folder. When a user copies or stores a new file on an NTFS partition, he or she has ownership of the file, and the disk quota program counts the size of the file towards the user's disk quota.

Disk quotas do not support file compression, and when the Disk Quota program counts disk usage, it is based on the size of the uncompressed file, regardless of how much disk space it actually occupies. This is mainly because different types of file types have different compression ratios when using file compression, and two files of the same size may have very different sizes after compression.

When a disk quota is set, the remaining space in the partition report refers to the remaining space within the user's disk quota.

The disk quota program tracks and controls disk usage independently for each partition, regardless of whether they reside on the same physical disk.

The operating system can monitor the disk quota, it can scan the disk partition, monitor the disk space usage of each user, and use different colors to identify the users whose disk usage exceeds the alarm value and quota limit, so as to facilitate the management of disk quota.

Multiple users logged on to the same computer do not interfere with each other's ability to work; One or more users do not monopolize disk space on a public server; In a shared folder on a personal computer, users don't use excessive disk space.

In summary, it can be seen that disk quota provides a user- and partition-based file storage management, so that administrators can easily use this tool to reasonably allocate storage resources and avoid system crashes that may be caused by uncontrolled disk space usage, thereby improving system security.

It has an impact, because it can't be written, and it can't be written or updated when it's upgraded.

You can set permissions for users, change the ownership of disks to administrators, or limit the quota of users.

Yes, you can select the quota item in the disk quota, and then you can set the user group to zero and the administrator group to increase it.

Disk quota management will result in the allocation of disk space, which is more useful on systems that are shared by multiple people, but not necessarily by a single person.

Setup method: 1. The method is as follows: in "This Computer", right-click a disk partition whose capacity you want to limit, such as f:disk, and select "Properties" to open f:

3 If you select Enable Quota Management, the following settings will change from gray unavailable to configurable. After the settings are complete, click OK and the Enable Quota System prompt will pop up as shown in the following figure to confirm whether to enable the quota system. Click OK to enable the disk quota system.

4 Set the disk quota for the specified user, except for the new user, if you want to set the disk quota for the existing user, then you can do the following: First, as in the previous steps, you need to open the "(f:) Quota Settings" window. As shown in Fig

5 You also need to check "Enable Quota Management", since you wish to limit disk usage, it is also recommended to check "Refuse to allocate disk space for users who exceed the quota limit", now to restrict the specified users, click on the "Quota Item" button in the bottom right corner to open the "(f:) Quota Item" window as shown in the image below:

7 Enter the name of the user you want to restrict in the "Enter the name of the object to be selected" text box, and click "Check Name" on the right to display the full name of the user. Then click "OK" to open the "Add Quota Item" setting window, as shown in the figure

8 Select Limit Disk Space To, set the available disk capacity, and set the warning level. Ok, go back to the quota input window of (f:) and in the list you can see the user who just added the disk quota setting, as shown in the image:

9 Close the window and return to the Quota Settings (f:) window. Click OK to display the Enable Quota System. This completes the disk quota setting for the specified user.

Right-click on the user, select "Properties" to open the "Set User Quota" window, and select "No Restriction on Disk Usage".

Disk quota management allocates disk space by user, which is more useful on systems shared by multiple people, but not by a single person.

As a result, the C drive of the computer cannot install programs with more than the quota.

We use disk quotas to manage disk space with 3 advantages: multiple users logging in to the same computer do not interfere with the ability of other users to work; One or more users do not monopolize disk space on a public server; In a shared folder on a personal computer, users don't use excessive disk space. The disadvantage is that when we enable the disk quota, it will cause a slight increase in system overhead, which will lead to some performance degradation.

To solve this contradiction, you can take full advantage of the auditing capabilities provided by the Win 2003 disk quota by enabling and then disabling quotas on a regular basis to ensure the performance of your computer.
