Multiple Archive Tapes

We are running Online 5.0 on an HP-UX system which has only one DDS tape drive. We want to make two "identical" tape backups of our Online system. One tape is to remain on-site, the other off-site for security/disaster recovery. Our Online system is getting new data 16-20 hours out of each day. We cannot afford to take users off the database to let us do backups (that is one reason why we have Online). The problem is that in the 1-2 hours it takes for us to make one backup, the users have entered new data and the second tape will not contain the same data. In addition, the second backup will remove the logical log(s) that will have been created between the first and second backup. This can cause problems with restoration of the Online system. I cannot add a second tape drive for several reasons. How do others solve this problem? Thanks in advance for your assistance. -- Harold L.
