True but, modulo issues with open files and so on, which might or might 
not be a problem, one can break a shadow set to get a quick backup which 
one doesn't have to restore---just mount the backup disk (and 
immediately build another shadow set, unless you have more than three 
members so can remove at least two and keep at least two live).  If open 
files are a problem, then they are a problem for other means of backup 
as well.  If one can stop the application, then a 
shadow-set-disk-as-backup is quick and easy.  These days, disks are 
cheap.
