This section explains how to identify and resolve problems you
may encounter when attempting to backup or restore Exchange using
Windows 2000 Backup. Use the following information to learn more
about the problems you may encounter and how to resolve them.
Although performing a full backup of Information Store each day is
the best method to use if you need to restore data in the even of a
disaster, full daily backups take significantly longer than other
backup methods. A full backup archives every database in
Information Store to the backup media. Other backup methods, such
as the differential backup method, take less time to perform.
Differential backups only archive data that has changed since the
last full backup.
Solution
To save time, use a backup plan that includes a combination of a
full backup one day a week, and incremental or differential backups
on the remaining days of the week.
For more information on preparing to back up and restore
Information Store, see Microsoft Exchange 2000 Planning and
Installation.
If you deleted your Exchange server from Active Directory before
performing a disaster recovery of your Exchange server, you cannot
reconnect your Exchange mailboxes until you perform the Remove
Exchange Attributes task.
Solution
To resolve this issue, use Exchange Task Wizard to remove
Exchange attributes and then attempt to reconnect the Exchange
mailboxes to the Active Directory objects.
Warning Do
not attempt to remove Exchange attributes until you have discussed
the need to perform this procedure with Microsoft Product Support.
For the most up-to-date information about how to remove Exchange
attributes, see the Microsoft
Knowledge Base .
To enable an Exchange mailbox reconnect:
Use Exchange Task Wizard to remove
Exchange attributes from the Active Directory objects you want
to reconnect.
