Hi Jose I did some analysis on this for monthly backups and discovered that a monthly archive and a monthly incremental worked out about the same in our environment but that the monthly archive was easier to implement. Our requirement was just a point-in-time each month with one month each year kept "forever".
In your case, if it is a real requirement that every backup be kept, Create a new copypool extend your retention to 210 days every 180 days, backup all primary pools to your new copy pool take a database snapshot and ship it and all your new copypool tapes to storage for 4 ½ years Delete the volumes in the new copypool The other thing that you might like to do is run q content on each of the volumes and drop it into a database somewhere, so that you can tell if you have a particular file and which tapes are required to get it back without huge amounts of effort.

I currently have a retention period for backups of 180Days. We are debating the scenarios - Wondering if I can poll the list to get possible suggestions or ideas for handling this. Some things that we have been discussing are 1) extend the retention period to 5 years and set nolimit to versions created.. deleted etc 2) create separate mgmtclass for once a month backups with retention period of 5 years 3) generate backupsets once a month and retain for 5 years 4) create separate TSM instance to provide 5 year retention 5) Using archive with 5 year retention Would appreciate any ideas and potential ramifications I currently have 180 unix and intel clients, storing 15TB onsite and 15TB offsite. My db is approx 55GB I am using TSM 5.1.5.4 on an IBM RS/6000 (H80 with 6cpus and 8GBs of ram) running AIX 5.1ML03. Attached are 2 x3584 with 8 LTO fibre drives for backups. For archive I use 3494 library (L12 and D12 with 4x3590H1a drives).
