We are wanting to have a “mirrored” HA environment in case our main server went down. I was wondering what solutions or how others have set this up.
We were thinking about setting up a cluster server and having adminp replicate mail files over but wasn’t for sure if this would be to hog-heavy in our environment.
Cluster réplication is light regarding to the service provided, it is also very reliable. Only if the “passive” server restarts after a long time down, then all the bandwidth is used. If your line is dedicated it is not a problem.This solution also works trough internet connections : cheap but maybe less reliable depending on provider.
