title: Debian Jessie (proxmox) tar backup
body: <p>I have four servers each with same hardware specification running proxmox 4 with same configuration. Yesterday I tried to do tar backup on each of them. I created simple script:</p>
  
  <pre><code>tar -zcvpf /mnt/backup1/root_backup/root_backup_1.tar.gz --directory=/ --exclude=mnt/backup1/root_backup .
  </code></pre>
  
  <p>and save it as fullserver.sh placed in backup directory on main root tree.</p>
  
  <p>/mnt/backup1 is directory where second hard disk is mounted.</p>
  
  <p>Example script is for the server number 1. And It's the same on all other except directory names.</p>
  
  <p>What happened is that created *.tar.gz file is different in size on each server, varying from 100 to 400 Mb. And biggest problem is with the last one, where I did everything the same and output file is only 1 Mb in size. </p>
  
  <p>Do you see where I made a mistake?</p>
  
  <p>Thanks in advance</p>
