Sounds to me like something that should be (and has been) configured at the filesystem/block layers rather than at the Courier application layer. Take a look at projects like RedHat's GFS or Sun's ZFS. I don't know much about NetApps either but I know they do NFS very well (which Courier supports very well) and I'm pretty sure they can be configured redundantly.

Is it any feature in courier that allows me to inform backup storage paths?

Today I use unison to maintain a replica of our email files, configurations, ..., in a second server to use as a fast recovery backup solution. The problem is that unison uses a lot of resources and IO_WAIT is always very high.

So, I was wondering if it is any feature to inform backup storage paths for courier to save all its files always into two different paths. Does something like this exist?

If it does not exist, don't you think it is a interesting feature to be implemented?

Thanks and regards,

Hi,

If we work with a filer, an easier way to proceed would be to affect LUNS/filesystems to the "backup" server. This way, you don't have to copy anything... The rollback on the master server just follows the same process. After that, you have to secure your filer. (snapshot and so on)
