Create a tar archive of /var/log named /root/logs.

Solution:

mkdir -p /backup

tar -cvf /root/logs.tar /var/log

tar -xvf /root/logs.tar -C /backup

Detailed Explanation:

tar -cvf creates an uncompressed archive.

tar -xvf extracts the archive.

-C /backup tells tar where to extract the files.

This is a common RHCSA-style archive and restore task.
