Topic: Two or more iRedMail Servers synchronized

Is there some documentation on making two or more iRedMail servers synchronize so that they may be fault tolerant and contain the same users,passwords, and such in real time for the purpose of fault tolerance ??

Cheers;

Re: Two or more iRedMail Servers synchronized

One could use rsync or unison [0] for example to sync user mailboxes and config data.

Both backends (MySQL and OpenLDAP) have their own ways of replicating data accross node boundaries.

If you search the net, you will find a bunch of information on how to do both. One thing/solution I have become very fond of since 2 month now is couchdb; using couchdb (eg as backend) provides for replication out of the box.

Use rsync to synchronize the directories and mailboxes, and use ucarp for automatic failover.
