I've been through that situation with two of my customers. It was about 450GB of archived data which had to exported (using 3590-E1A tape drives). It took about 4 hours to bring up an old version of the database (we couldn't use a different TSM server an connect it to some drives and there was not enough space to bring up a second TSM instance at those customers), then it took about 20 hours to export the data, then bring the original TSM database back online. Be carefull that you don't get TSM client sessions running and deactivate all TSM client and admin schedules so that no tapes are being overwritten. At that old TSM database time tapes that were scratch then will be with data at the aktual TSM time. At least get a full and consistent set of OFFSITE Copy Pool Tapes before going "back in time". In a time frame of 20 hours something will be missed and the wrong tapes could be overwritten, so consistent OFFSITE data is essential.
If you have more question, you can always call or email me directly.
