If you are doing a Symmetrix sync ( not rsync ) you are pushing bits from prod to the other servers' disks, thusly you will need to shut down your target db or there will be corruption. Once the two are in-sync, it's time to split them. Once they are split they are each on their own
again, the target can be brought back up.

The oiriginal poster wants the disk copy as a backup. not to use for any othr purpose. Therefore, I don't understand this idea of "shutting down the target server" and "bringing it back up". You just the leave the disk copy intact, maybe refreshing it nightly, for years on end without ever pointing a server at it *except* when you need to use it.

The minute you bring Informix up on it the disk copy is destroyed as a potential source for a point-in-time restore using logical logs.

In a typical R5 array that is installed/setup by small shops, where they have 3xDisk for R5, you are right, but, in a proper setup where you have 5xDisks or more, then you will see a LOT of read performance that you don't get out of a Mirror - this is very much the case when you have LOTS of users accessing the server or have a SQL database that users are hitting. ... then install another RAID-0 or RAID-1 or single disk for page file, it's still not as fast as a properly configured system designed for SQL use. ...
