Thanks for the answers Wanda. Exporting all of the active backup data of all the servers in 1 command isn't an issue of course, just one command and you are sure that you don't miss anything. But if the full export is eg 2 TB and a restore is asked of a file that is of course at the end of the latest tape in the export process, would this require then the full reading/searching of all the tapes? The restore procedure would then become a rather time consuming job if there is no tape positiong info in the TSM database. Anybody with hands-on-experience in such a setup? Or can you find out which tapes were used for which node in the export messages and then just run the import on eg two tapes instead of specifying all the used tapes? Else the export should be done on seperate tapes for each node resulting in a high tape consumption and a lot of admin schedules of course. This would result that the export cannot be used in a practical way to export full backups out of the expisting primary storage pool on a regular basis (once a month due to the SLA agreements). I know of course the exoprt was not written for a such a task and a full backup is not in the TSM dictionary, but I'm just trying to be creative to answer the customer wish list. thanks, Kurt

If I want to export eg two clients A and B to the same volume (eg a tape vol001 that has enough space of course), can I specify twice the command: export node A filedata=backupactive devclass=<tape> VOL=vol001 export node B filedata=backupactive devclass=<tape> VOL=vol001 ==> I don't believe TSM will let you do that; it SHOULD tell you that vol001 is already in use. Or must I specify export node A,B filedata=backupactive devclass=<tape> VOL=vol001 to have both nodes exported to the same tape? ==> Yes, that is way to get both on the same tape. And what if want to run an import of node B only for a restore from the tape that contains the export of node A too with the command: import node B filedata=backupactive devclass=<tape> VOL=vol001 Will it go directly to the point on the tape where the export of B has been written or will it read the entire tape untill TSM finds the beginning of the export of server B? ==> If you say IMPORT NODE Devclass=<tape> VOL=vol001 TSM will import all nodes on the tape If you say IMPORT NODE B devclass=<tape> VOL=vol001 TSM will import only node B As far as I know, TSM doesn't save any tape positioning information that would let it skip to the data from B; I think it will read the whole tape.
