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...
