If you worry about server redundancy for your emails, we’ve got the solution for you.

We’ve recently made a HowTo page detailing how to setup GlusterFS with your Atmail server. GlusterFS is distributed file system for scalable file storage, allowing for the usage of files across servers. This allows you to have multiple copies of your system running at the same time!

Failovers, striping, replication, and load balancing for your Atmail servers? A breeze, with the GlusterFS system.

With the GlusterFS howto guide, you can setup two mirrored instances of Atmail. In the case the primary server goes down, the secondary server can kick in and handle all requests seamlessly. When the primary server is turned back on, the files added to the secondary server are automatically synchronised. Easy.
