We have Zimbra in a 50 user environment. We have been mandated to provide continuous access. What are our redundancy options? Here's what I see:
- we aren't running RHEL, so no cluster support (nor do I think we can afford the hardware to cluster)
- we've tried a second Zimbra install, but you can't simply duplicate data and any solutions seem fragile and "hackish" (like the heartbeat/cold server setups in the wiki and forums)
Would the best option be to run a light email server such as squirrelmail at a separate location as a lower priority on the MX and with the same accounts?
