Simple to understand and execute, [root@station ~]# yum install bzip2 [root@station ~]# tar -cvf /root/backup.tar /usr/local/ [root@station ~]# du -sh /root/backup.tar 20K /root/backup.tar [root@station ~]# bzip2 /root/backup.tar [root@station ~]# du -sh /root/backup.tar.bz2 4.0K /root/backup.tar.bz2 [root@station ~]#

I don't think this is right answer as the question explicitly asks "tar must use bzip2 to compress". Apart from that the answer provided is perfectly valid.

Answer for RHEL8 # cd /usr/local # tar -jcvf /root/backup.tar.bz2 /usr/local # mkdir /test # tar -jxcf /root/backup.tar.bz2 -C /usr/local If you do it the way the original answer says it will return the "cowardly refusing" error
