18 – Archiving And Backup
One of the primary tasks of a computer system’s administrator is keeping the system’s data secure. One way this is done is by performing timely backups of the system’s files. Even if you’re not a system administrator, it is often useful to make copies of things and to move large collections of files from place to place and from device to device.
In this chapter, we will look at several common programs that are used to manage collec- tions of files. There are the file compression programs:
● gzip – Compress or expand files
● bzip2 – A block sorting file compressor The archiving programs:
● tar – Tape archiving utility
● zip – Package and compress files And the file synchronization program:
● rsync – Remote file and directory synchronization
