You need to backup /var/vmail, /var/www (or the place where you stored the websites), the ispconfig database, all mysql databases of the websites incl. the “mysql” database, the users and passwords in /etc/passwd and /etc/group. Make sure that you backup the directories with preserved permoissions.
We must backup:
c. /var/www (web content)
b. /var/vmail (mail content)
a. /etc/passwd and /etc/group (users)
d. MySQL databases (is it better to stop mysql and tar.gz the /var/lib/mysql?)
e. All /etc/
f. /var/log
