Linux Shell Scripting Cookbook - Third Edition

How it works...

Like tar, fsarchiver examines the filesystem to create a list of files and then saves those files in a compressed archive file. Unlike tar which only saves information about the files, fsarchiver performs a backup of the filesystem as well. This makes it easier to restore the backup on a fresh partition as it is not necessary to recreate the filesystem.

If you are seeing the /dev/sda1 notation for partitions for the first time, this requires an explanation. /dev in Linux holds special files called device files, which refer to a physical device. The sd in sda1 refers to SATA disk, the next letter can be a, b, c, and so on, followed by the partition number.
