→Part 1: Backing Up Virtual Machines
{{Admon/important |Please be patient|It may look like the command prompt is stuck but it could take a while for gzip to compress an entire operating system. '''NOTE:''' Do NOT press '''<ctrl>c''' to cancel this process. If you do, your archive will become incomplete and your recovery will be corrupt.}}
<ol><li value="7"> Compare the size of the compressed and original files (hint: use '''ls -lh'''). If file is very large (like 15GB), you didn't compress it and you need to remove that file and perform the previous step until you get it right!</li>
<li>Once you are '''sure you have all three VMs backed up''', use the <b><code><span style="color:#3366CC;font-size:1.2em;">exit</span></code></b> command to revert back to your normal user.</li>
<li> Start the '''''centos3''''' VM.</li>
<li> '''Make certain that you are in your VM and <u>not</u> in your main system!''' </li>
