backup - retention with 0 days on TSM 5.5

Hi max, and what about the 0 days on backup-restore retention? Is this value correct?
This domain is the PRODUCTION, the most important backups we need to take care.

Hi,
well that depends on waht you want: for some tdp products, or brms, you may want to create a dedicated domain whose retention is really managed by the tdp product itself, and thus you set verdeleted, retextra and retonly parameters to 0 to strip off this from tsm server. I don't know if it is your case though.

Hi max.. sorry the delay but we're very very busy these days..:)

I  don't understand your answer well...   I have read on the help page of ICS I see this backup/archive retention policy are for doamins:

Use the Policy Domains Properties to view and change policy domains for a server. A policy domain defines the policies for backup, archive, and migration operations on client nodes assigned to the policy domain. The policies also help you to automatically meet business requirements for protecting and retaining data.

Policies include settings such as these: 
•How and when files and directories are backed up and archived
•How space-managed files are migrated from client nodes to server storage
•Where backed-up, archived, or migrated files are initially stored
•How files are managed by the server (how many backup versions are kept, for how long)
Assign client nodes with similar requirements for data protection to the same policy domain.

If you see other domains, on the image attached, have retention/archive policy not to 0 days as produccion domain and we dont understand yet which is the meaning of '0days' of retetention for this domain..

Thanks MAx
