Terabytes of archived redo logs

Hi folks,

I'm about to inherit an interesting project - a group of five 9.2.0.6 databases that produce approximately 2 terabytes (!) of archived redo log files per day.

Apparently the vendor configured the HP ServiceGuard clusters in such a way that it takes over an hour to shut down all of the packages in order to shut down the database. This amount of downtime supposedly can't be supported, so they decided to go with online backups and no downtime.

Does anyone out there have any suggestions on handling 400 gig of archived redo log files per day? I was thinking of either a neear-continuous RMAN job or shell cron that would write the logs to either tape or a storage server. Actually, I think that our tape library might be overwhelmed also by the constant write activity. My thinking right now is a storage server and utilizing a dedicated fast network connection to push the logs over. Storage though might be an issue.

If anyone has any thoughts or suggestions, they would be appreciated. BTW, I already had the bright idea of NOARCHIVELOG mode and cold backups. :)

Thanks,
Lou Avrami
