How are the following TSM parameters seen from LiteSpeed:
1. Versions kept while a file exists (VERE)
2. Extra versions kept while a file exists (RETE)
3. Number of versions to keep if a file is deleted (VERD)
4. How many days to keep the last version of a deleted file (RETO)
Both @RETAINDAYS and @EXPIRATION are entirely ignored with TSM backups.
TSM-based backup retention semantics are handled by the TSM management class specified.
