Hello. This is not the way that TSM works. You need to understand the TSM system of "progressive backups", where a file is backed up only once. If it never changes, it is never backed up again. Every day, only the files that change get backed up. The TSM Database keeps track of all this, and allows you to do a complete restore if you need to, getting each file from the tape it was written to. I suggest looking in the manual "TSM Administrator's Guide" which you may be able to find in your own language for easier reading. There is an English copy at http://publib.boulder.ibm.com/infocenter/tivihelp/v1r1/index.jsp.
You have two separate backup requirements. One is the normal working backups. Instead of weekly overwrite and so on, you need to set these up with 7 inactive copies, keep inactive copies for one month, and use normal TSM progressive backups. You will find that normal TSM progressive backups are MUCH faster than overwriting a full backup every 2 or 7 days, use a LOT less tape, and that it gives you better protection. For fastest restore, these should probably be set up with TSM collocation. Your monthly archive is a separate problem. This should be a TSM archive process, set to be kept for 2 years. This would be a full archive copy. Multiple backups will be written to the same tape, until it is full. The same tape can have backups from different dates on it. This is normal, and it saves tape. The tape will be reused and overwritten automatically when enough of its files have expired that it can be copied to a new one. The default is when it becomes 50% empty. Do not forget that you also need to back up the TSM Database to tape. Hope this helps get you started. It is a different way of working in TSM. You do not have the usual cycle of weekly full backups and daily incremental backups. TSM is very different - you never do a full backup after the first day, because you do not need to. This confuses a lot of people, but once you understand how progressive backups work and how the TSM database keeps track of everything for you, then you will understand how it is really better. Contact your local IBM office and have them order a copy of the TSM Concepts Poster for you. It is free, and it makes of these concepts a lot easier to understand. The poster is IBM publication number SC32-9464-00.
