Description: Exchange Mailbox backups and restores are slow.
Inherently, Microsoft Exchange mailbox backups in NetVault are slower than most database backups. This is due to the fact that, in order to back up mailboxes on a 'brick-level,' NetVault has to impersonate an Exchange mailbox account and authenticate for each individual mailbox item, whereas a database backup is streamed to NetVault in one continuous data package. At this time we use MAPI to access the Exchange database, this is why you will notice slow transfer rates when backing up or restoring on those jobs.
