Hi - Wondering if I can get ideas or suggestions

We need to retain all backups for a 5 year period. 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).



Thanks
