Yesterday I tested the restoring of zimbra and found something strange.
I used A Simple Shell Script Method to backup zimbra every night by cron. And yesterday I built another zimbra server to test the backup-restoring of zimbra. Everything seemed OK untill I tried to login to my account. I got a wrong username/password error. I tried my old password that I changed it a month ago and entered successfully! After checking my mailbox I found that all the mails is up-to-date(I have all the mails just before the backup yesterday), but the Preference settings are not! I remembered I changed the password/theme/layout a month ago but I could not find them in the mailbox restored from yesterday's backup!
So why the backup of zimbra can restore all the mails but can not hold any new Preference setting? Is anything wrong when backup?
