We don't have the requirement for email archiving, so I can't address that question.
I would first ask, what do you mean by "when there is a problem with the tape??!?" I assume when you say "restore of the tape", you mean recreating the tape using RESTORE VOLUME from your offsite/DR tape? I would be shocked to find out you have had "problems" with an LTO2 volume that caused you to do a RESTORE VOLUME more than once in a year, and my response would be to address THAT issue. In the meantime, a quick and dirty solution is to have TWO tape copy pools. Keep one onsite, as well as the one you keep offsite. (If you don't have room in your library, put the 2nd copy pool tapes on a shelf outside the library as they fill up.) That way, if you can't read your onsite tape, mark it DESTROYED, and restores will take place from the onsite copy pool tapes. After you have met your SLA that way, you can let the RESTORE VOLUME take as long as it needs, won't affect your SLA's. (BUT, fix those tape issues ASAP.)

Background: TSM Server 5.2.3.5 AIX Op System 5.2.2.0, P650 box Library -ADIC I2000 Scaler, LTO 2 Drives Looking for feedback from the group. We have currently have a partioned library, 10 drives for all our system backup. The other library partition, with 2 drives for content manager. We are using content manager, via common store for email archiving. The problem is when there is a problem with the tape, there are thousands of small files on tape..and the restore of the tape is taking 20 hours to move the data off a tape. Seems that using LTO tape is not the answer with all of thousands of individual emails on one tape. Business SLA for email archiving is 24 hours. We are looking at increasing our disk pools, and keep all data on the disk...and of course, still keep offsite copy for DR purposes at this point. Interested in any suggestions? What are you doing for email archiving?
