UDFS, backups and BRMS

  I just created three UDFS files in /dev/QASP03.  I mounted each of 
my three Domino data directories to one of the UDFS files and moved 
the data to them.  It works great.  I was changing my full system save 
control group in BRMS and got thinking.  I know the file systems have 
to be UNMOUNTED to have BRMS save the UDFSs in QASP03 but at some 
point I need to MOUNT them back for the contents to be availible for 
backing up.  
Right now I UNMOUNT them right at the beginning of the backup because 
I'm not sure at what point the contents of /dev are saved.  I have a 
List Type (*LNK) called SAVSYSIFS that pretty much saves the entire 
IFS with the exception of the MAIL folder under my mail server.

Does saving the configuration (*SAVCFG) save the UDFSs 
in /dev/QASP03?  I could remount them after that and they would be 
availible for the SAVSYSIFS.

Thanks in advance,
m.
