Hi I have some questions and i'd be happy if you help me 1. I have installed Debian 4 etch with ISPConfig 2.2.18 and my questions is can I update it to 2.2.21 without previous versions 2.2.19, 2.2.20 ?? I mean is this correct 2. I have more than 200 email accounts on my server, so first I think to make a back up of my server. So I think to use Partimage (here I find a guide: http://www.debianadmin.com/backup-and-restore-linux-partitions-using-partimage.html) For example when I type: #fdisk -l , this is the result - Disk /dev/sda: 248.9 GB, 248999051264 bytes 255 heads, 63 sectors/track, 30272 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 29942 240509083+ 83 Linux /dev/sda2 29943 30272 2650725 5 Extended /dev/sda5 29943 30272 2650693+ 82 Linux swap / Solaris So I must back up the first one sda1 right ? 3 And after that I think to upgrade to 2.2.21 , I know that it makes it owns back up but I want to do all this because some of my friends tell me that they have some problem while updating ISPConfig and now they don't do the updates.. So please tell is all this is right and if you have any suggestions about other back up software please tell me Thank You in advanced !
