From workstation, run the lab archive-manage start command. The command runs a start script that determines if the host, servera, is reachable on the network. The script also ensures that the file and directory to be created in the exercise does not exist on servera.

[student@workstation ~]$ lab archive-manage start

Use the ssh command to log in to servera as the student user.

[student@workstation ~]$ ssh student@servera
...output omitted...
[student@servera ~]$

Switch to the root user as only the root user can access all of the content of the /etc directory.
```
[student@servera ~]$ su -
Password: redhat
[root@servera ~]# 
```
Use the tar command with the -czf options to create an archive of the /etc directory using gzip compression. Save the archive file as /tmp/etc.tar.gz.
```
[root@servera ~]# tar -czf /tmp/etc.tar.gz /etc
tar: Removing leading `/' from member names
[root@servera ~]# 
```

Use the tar command with the -tzf options to verify that the etc.tar.gz archive contains the files from the /etc directory.

[root@servera ~]# tar -tzf /tmp/etc.tar.gz
etc/
etc/mtab
etc/fstab
etc/crypttab
etc/resolv.conf
...output omitted...

On servera, create a directory named /backuptest. Verify that the etc.tar.gz backup file is a valid archive by decompressing the file to the /backuptest directory.

Create the /backuptest directory.
```
[root@servera ~]# mkdir /backuptest
```

Change to the /backuptest directory.

[root@servera ~]# cd /backuptest
[root@servera backuptest]#

List the contents of the etc.tar.gz archive before extracting.

[root@servera backuptest]# tar -tzf /tmp/etc.tar.gz
etc/
etc/mtab
etc/fstab
etc/crypttab
etc/resolv.conf
...output omitted...

Extract the /tmp/etc.tar.gz archive to the /backuptest directory.

[root@servera backuptest]# tar -xzf /tmp/etc.tar.gz
[root@servera backuptest]#

List the content of the /backuptest directory. Verify that the directory contains the files from the /etc directory.

[root@servera backuptest]# ls -l
total 12
drwxr-xr-x. 95 root root 8192 Feb  8 10:16 etc
[root@servera backuptest]# cd etc
[root@servera etc]# ls -l
total 1204
-rw-r--r--.  1 root root       16 Jan 16 23:41 adjtime
-rw-r--r--.  1 root root     1518 Sep 10 17:21 aliases
drwxr-xr-x.  2 root root      169 Feb  4 21:58 alternatives
-rw-r--r--.  1 root root      541 Oct  2 21:01 anacrontab
...output omitted...

Exit from servera.

[root@servera backuptest]# exit
logout
[student@servera ~]$ exit
logout
Connection to servera closed.
[student@workstation]$

Finish

On workstation, run the lab archive-manage finish script to complete this exercise.

[student@workstation ~]$ lab archive-manage finish

This concludes the guided exercise.

Hello,I am trying to finish up Lab 3 of the Chapter 15 Comprehensive Review Labs in RH124, and when I type in sudo dnf install zsh for the 6th specification of the lab, I get an error message basically saying that it failed to download metadata for the repo 'ansible-2.9-for-rhel-9-x86_64-rpms', and that they could not download repomd.xml. It provided a 404 status code.Can someone please let me know what the problem is, and if there is a current workaround? Thanks.
