Hello, This sounds like you just need a management class setup to immediatley expire files deleted on the workstation.
You can do this with the VERsionsDeleted and RETainOnly parameters in a backup copygroup. If you set them both to 0, the next time an incremental is run against the workstation, TSM will notice the file is deleted and mark it for expiration. Next time expiration runs on the TSM server, the file will be deleted from its inventory.

I believe "what goes around comes around" with the caveat "but not always in the way you expect!" in terms of how it gets back to you, so I try to help and volunteer in other subjects I have more expertise in to keep the cycle going. Anyway, to clarify the client need, once a particular file is deleted from a particular network workstation, he merely wants to make it impossible for that file--which was previously backed up--to be restored back to the original location from the backup tape. Fortunately, he doesn't care whatever method I use to prevent the file from being restored. If it's as simple as having the application take a selected file and scripting dsmc to do an immediate expiration, he will be happy. Meanwhile, I have to wait for him to have someone forward me the technote you suggested since I don't have the IBM number--GRRRRR! But at least I can rephrase the question to "How do I prevent a single file from being restorable?" Thanks again, Brian J. Matuschak Ciber, Inc.

Welcome to the product, and the List, Brian. >From time to time we see postings like this from client customers who spring for a big, expensive product like TSM and then completely ignore what it's all about, seeking instead to have it do things which are contrary to its nature. Very much a Dilbert P.H.B. scenario. That client may not use Archives, but obviously should for this expressed need. You can otherwise try to bend the product to make it do what they want, but I doubt that anyone involved in the effort will be happy with the result. Stay away from anything which is not a standard, supported part of the product, which is to say Delete Object. There are procedural alternatives: one is found in the IBM site Technote 1166278, "How to remove a single file from a TSM backup tape volume". But not trivial. Another approach is to employ limited retentions for Inactive files and then do 'dsmc EXPire'; or do a selective backup on an empty surrogate file to push the real data out of existence in the TSM storage pool; or just Exclude the file to incite its expiration. Overall, though, I don't get the sense that the client has fully defined EXACTLY what they want to achieve. A file not in the Backup storage pool implies that the file is no longer in the originating file system - which doesn't seem like the situation they'd have (but which is the inherent, most simple way that files expire out of TSM). That client obviously does not understand what "backup" means, or perhaps care. Archive was created for what they want to do. Have them define their requirements in detail, and then outline the aspects of the product which meet their needs. Beyond that, a whole different methodology - and perhaps product - would be called for.
