They both have the same management class with the same "expire date/days" and nothing for "expiration by non-useage".

I know that 3 of them must exist when the dataset is not deleted. One backup when deleted. I confirmed that there is a backup when the dataset is not longer catalog by recalling it with "hrecover". </snip> HLIST DA(' dsname') BOTH Also verify you are using EXPIRATION BY DAYS and not EXPIRATION BY NON-USEAGE. They are represented in the DFSMS online panels by: EXPIRE DATE/DAYS and EXPIRE NON-USEAGE respectively. With EXPIRATION BY NON-USAGE *any* reference (even just to look at the vtoc without opening the dataset) to the dataset will reset the expiration counter to the date of that reference. The online help panels are very good for these two items. Read them carefully. BTW, given that the dataset exists, based on the previous entries in this thread, anywhere from 0 to 3 backups may be validly present.
