Help on Archive

Hi all, I am faced with having to do an archive of a 75 GB database within a 6 hour time frame. We cannot perform an On-Line archive because our clients do not wish to add the complexity of administrating logical log tapes spaning over different days, and the degregation of performance. I have looked at the following options: Informix Version 6.0 on Sun Solaris 2.3 on RAID 5 ==================================== 1) onarchive - too slow and buggy 2) dd - we can dd from one raw device to another, then perform ontape on the later via another instance. This method will not update the archive information on the "real" instance. This information is necessary for full and logical log restore. 3) optimize RAID - Informix seems to max out reads at 2 MB/s Vs. 3 MB/s using 'dd'. This is due to page qualification Informix has to perform to determine if the current page should be archived or not. Any suggestions would be greatly appreciated.
