Hi Well, we have that issue as well. We have large DB/2 and Oracle database(+2TB) doing logbackups every ½ hour to the system.
The unload/load process isnt something you should run every two weeks. Perhaps once a year or with two years in etween would be a good idea. I think you should have no problems having the system down once in two years for the unload/load process. Every time we need to have the system down for maintenance, we need to request down-time three weeks in advance. The system is on a 24/7 production time and is monitored 24 hours a day by our operators. This however doesnt stop us from having the system down for maintenance every second year.

Many places can't have their TSM servers down for more then 8 hours. We have Oracle and SAP DB's that use TSM to archive their logs. If we are down for up to 8 hours they can survive but if we were down for 24 I'm sure many of their log directories would fill and the DB would crash.

If we had choosen not to do the audit, the process would have taken about 28 hours.
