Introduction to UNIX/Linux
Lesson Title:
Managing Packages and System Backups (slo-07)
Learning Outcome:
This chapter covers the mechanics of
package installation in general, using any of three common packaging schemes. This chapter
also covers tools and procedures you can use to protect both system packages and user data
by backing up the computer. Although they’re often overlooked, system backups are critical;
having good backups can greatly reduce downtime in the event of a disk failure, a system
break-in, or even just an accidental deletion of a critical file. Several backup options exist, in
terms of both the hardware used to back up data and the software you use to do the job.
Key Concept: (page 48 of the textbook)
A running Linux system consists largely of processes—that is, programs that are active. Linux
provides tools that enable you to view, start, stop, change the priority of, and otherwise manipulate
processes.
