open Access files

[Gill, Geoffrey L.]

Hello again all,
I was wondering if anyone can tell me how they deal with Access (.mdb) files. 
If thesse files remain in an open state when the backup runs are there any 
issues? Will they get backed up? Will they be in a useable state when restored 
if they do get backed up while open? We know from past experience open Oracle 
files are not, which is why tools are available to back these up, but I'd like 
to hear from anyone who has experience the .mdb's.
 
Thanks for the help.
