Neil, I feel your pain. I've been thinking my way 'round this one for a while, but I see no easy solution. All I can suggest to give them precisely what they want is a restore to point-in-time followed by an archive. However this will produce 9 full copies of the data and is likely to use up more tapes than you currently use, plus need the disk, server and admin resources to do the work. I'd suggest that this is will probably cost more than the savings in tapes will provide.
The only other alternative would be for them to clone the TSM Server instance, set up a one month retention and backupsets paradigm and then leave the previous instance shutdown/idle until needed for a restore. The historical tapes could be checked out until needed. Hope this helps Steve. Steven Harris AIX and TSM Admin, seeking work Sydney Australia - willing to move for the right job.

I have a question - please do not ask for an explination - it is what the customer wants. Environment: -TSM Server 5.4 on AIX -TSM BA client on Linux, Solaris and Windows (various flavors) -TS3500 tape library with TS1120 drives (+1TB on each tape) The customer desires me to convert the last couple of years of backup data - all of which has 3 year retention - to look like periodic full backups. - Data between 1 and 6 months old - only the end of month backup - Data older than 6 months - only one backup at the end of the year Similar to a traditional backup where fulls are periodically taken The customer's data from their 160 clients occupies nearly 500TB of tape space (primary only) and is looking to cut down on the number of tapes that they would be required to purchase. This will be a one time effort since the customer is now performing their own backups and I would like the customer to take custody of this legacy data. One thought is to create backup sets of each client at the specified points in time. Your ideas are appreciated. Thank you Neil Strand Storage Engineer - Legg Mason Baltimore, MD.
