System Administration

How to set up, use and maintain disk quotas for your Linux system.
How Users Can Check Their Quotas

Every user or group can check their disk quota with the command quota. This command produces a report that contains information for all file systems listed in the /etc/fstab. Give the command quota -u (for user quota) or quota -g (for group quota) or a combination to obtain this information. If no quotas are set, the command quota -u results in the following output:

Disk quotas for dsnjaro (uid 503):none

If quotas have been set, the output looks like:

Disk quotas for user dsnjaro (uid 503):
File system blocks  quota  limit  grace  files  quota  limit grace
/dev/hda3   49   100   110       30    0    0
Only the system administrator can use either of the commands:
quota -u <
quota <-g <group-id>
Quota is working very well for me in my work, where there are approximately 300 users on our system.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
