I know something like this has been asked many times. Right now we are running Zimbra on a physical server and I want to see if there are good options to make sure there is minimal downtime if there is hardware failure or data corruption on the server itself.
How does everyone make sure that they can get backup quickly if there is hardware failure. What about data corruption ? My understanding is the full backups will backup everything including LDAP and the mysql database. Is this enough to get up and running on a new server?
I think virtualizing zimbra would allow us to survive hardware failure. My only concern is using something like NFS or iSCSI can it handle the I/O that zimbra needs to operate without any problems?
My understanding is that something like Zimbra clustering requires RHCS and that is primarily for load balancing. Is that correct?
