Thank's everyone for your reply, it help me a lot. Wanda hit exactly the sensitive spot. The organisation don't want to spend a lot of time and money to look after many user type, different need in data protection. And, I know very well if, I ask the majority of Recerche kind of users, what they want, it could mean opening the pandora box. It could also mean to adapt the electronic data to the paper conservation rules ask by ressource department.
That said, I like what Gary wrote. One new node name for short retention and keep original node name for long term. I don't think I will want to use the TSM archive. I use that option when I can remove the original file from disk. I think it will use less space if we do a monthly incremental with verexists=12, verdel=12, retextra=362 and retonly=362 (or more depending of exceptional client request) Comment's ? +---------------------------------------------------------------------- |This was sent by alainrich...@hotmail.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +----------------------------------------------------------------------
