Michael,

The rules I described apply universally to backup objects with the same name
owned by a given node in backup storage.

With TDP products, in some cases, the backup objects are given different,
unique names every time a backup occurs -- you must review the Install &
User's Guide for the TDP you are using.  For example, TDP v1 for Exchange
creates unique names for every backup, so retention/expiration must be done
manually;  in v2 of this TDP, objects stored in backup storage are given the
same name, so their retention/expiration becomes "automated" like for files
backed up by the b/a-client -- and the management class rules, as I
described, will apply.

Hope this helps.
