If for some reason point-in-time isn't exactly what you were looking for, keep 
in mind that when you go to restore individual files or sets of files, there 
are options to look for "inactive" files, files that are not the most recent 
copies of a file, or files that were deleted after being backed up. 

All of this depends on your management classes and the management classes' 
copygroups being set up to retain inactive or last copies of a file as long as 
you might need them, and as many versions as you might need. These retention 
policies probably are something unlike other backup programs, so it is worth 
some time to get to understand them.
