Try  dsmc PREview  and see if it provides the info you seek.

An in-client preview can't tell you how long a networked backup is going to 
take or gauge the effects of a large Incremental contending for memory with 
other apps in the client system, where paging can cripple a backup.  I'd advise 
performing analysis to identify the slowest ingredients in your backups and see 
if they can be addressed.  Exploration of journal-based backups or target area 
backups may be in order.
