I am renting a single server, on which I installed ubuntu 12.04, postfix and dovecot (and ISPConfig).<\/p>\n
I would like to backup the full postfix+dovecot configuration, in order to restore it in case of a HDD crash.<\/p>\n
I will need to restore all the imap mailboxes (users names, passwords, etc.) as well as the mails and the folders.<\/p>\n
In short, someone with a mail account on the server should not be able to see there was a server crash, unless he\/she tried to connect to the server during the short period of time during which it was under maintenance.<\/p>\n
My question is:<\/strong><\/p>\n Which files should I backup ? Ideally, I should backup some configuration files each time I create or delete mailboxes, and other files (that contain the mails) very frequently.<\/p>\n I have already found that I should backup Originally posted 2014-01-02 12:06:32. <\/small><\/p>","protected":false},"excerpt":{"rendered":" I am renting a single server, on which I installed ubuntu 12.04, postfix and dovecot (and ISPConfig).
