I would like to know if one of you know how to backup all the owner from files with IBM Tivoli ?

Right now, using the lastest version of TSM, the files owners are replaced by the "servername" after their backup up by Tivoli. Restoring is very complicated when you used QUOTAS ... :/

Is there any NSS parameters or tools under Linux who are able to backup all the owners on a particular NSS volumes ?

Any suggestions will be appreciated.
