In V5.1 and up you can specify linked copy pools and actually create the primary and the copy pools at the same time, but you have to have 3 tape drives.

The tapes contents should be identical. Create a primary tape storage pool (call it primtape1) and two copy storage pools (call them copytape1 and copytape2). After backups complete, run backup stg primtape1 copytape1 backup stg primtape1 copytape2 upd stg diskpool hi=0 lo=0 and when diskpool-->primtape1 migration is complete: upd stg diskpool hi=90 lo=70 (or whatever your diskpool migration levels are) (This assumes, of course, that you're using a disk cache to catch client backups.) Contents of all three tapes may not be absolutely identical, but they'll be pretty damn close. (If you're looking to clone the contents of one tape to another tape via an OS utility like tcopy or dd, you may or may not get a usable tape.) -- Mark Stapleton ([EMAIL PROTECTED])
