>First of all, does it cause any problem? You don't want to do this unless (a) you copy the index files as well, (b) your backup sofware doesn't lock the copying files for writing, i.e. is a true open file backup, (c) your client realizes that they can still lose up to one backup-frequency's worth of messages and (d) you can ensure that any user add/change/delete operations, including forwards and rules, are propagated to both servers. If any of these requirements are not met...well, I can't even begin to tell you how messed up things could get.
>I was thinking to cluster servers or use DFS of Active Directory. DFS won't really help you in this area. MSCS, however, will, as would Double-Take or Vinca/Legato. The third-party options cost less in hardware but a substantial amount in software. MSCS is free but requires HCL hardware. Clustering, by design, does not have the first paragraph's requirements and is a much safer choice if your client is serious about redundancy and real-time backup.
