We are using Zimbra opensource edition for last few years. Some times, we have some server hardware issues or other file system crass issues comes in, In that time we face lot difficulties to restore the mails to the new server and it took nearly a week to comfort with new server.

My Question, How can we setup a secondary Mail Server for our zimbra server. We need to update secondary server every end of the day or some period. So If the primary server down, Users should be automatically able to redirect or pull the mailboxes from secondary server without any delay.

Kindly advice us to do this secondary setup using zimbra ?

Thanks in advance !!!!!!
