I agree with all of you. It should not take so much time...  disks are 
on a local raid5 box.  I think the time is spent extracting people's 
mailboxes from the db and copying them to disk...  but still, it takes 
way too long...

How do you restore a single mailbox or some emails?  Do you have to 
restore the hole db and then extract the relevant emails?  If so, it is 
a waste of time and resources...  unless there isn't any other way...  I 
think this is what they are trying to avoid but obviously it is not 
working very well...

Thanks!

Denis
