Since only the root user can read all the contents of the /etc directory, we are going to back up the directory and log into serverX as root.
```
[student@desktopX ~]$ ssh root@serverX
```
Create an archive of /etc using gzip compression to back up the configuration file directory /etc. Save the file as /tmp/etc.tar.gz.
```
[root@serverX ~]# tar czf /tmp/etc.tar.gz /etc
```
Verify that the backup file etc.tar.gz is a valid archive by decompressing the file to a newly created directory named /backuptest on serverX.
1. Create the target directory /backuptest.
```
[root@serverX ~]# mkdir /backuptest
```
2. Switch to the /backuptest directory, where we will extract the files from the etc.tar.gz archive.
```
[root@serverX ~]# cd /backuptest
```
3. Extract the etc.tar.gz archive to the /backuptest directory.
```
[root@serverX backuptest]# tar xzf /tmp/etc.tar.gz
```

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.
