Prerequisites and operational notes for restoring Exchange individual mailboxes, mailbox folders, public folders, or messages
Review the following information before you restore individual mailboxes, mailbox folders, public folders, or messages:
The destination mailbox must exist to successfully restore a mailbox.
When you restore mailbox messages or public folder documents, the option overwrites the contents and properties of the original objects. Messages are overwritten regardless of their location. (For example, if the messages were moved to the "Deleted Items" folder.) If the original message no longer exists, a new message is generated with the same contents and properties. A new message is also generated if a new destination location is entered.
If the option is selected, NetBackup skips the restore of any message that still exists, regardless of the current location.
Note that if the original message(s) no longer exists, a restore of the message(s) generates a new copy every time it is restored. A restored copy of the message does not count as the original message in the existence check.
Restores that use Granular Recovery Technology (GRT) must be made from a disk storage unit. You cannot restore from the tape copy.
NetBackup can back up the online archive mailbox for users. However, a restore from a backup using GRT by default restores the items to the user's mailbox and not the archive mailbox. Items are restored starting at the root of the mailbox hierarchy. Alternatively, you may want to redirect the restore to the path
Top of Information Store\Inbox\Archives\.Exchange Server provides a feature to retain deleted items for a period of time after you "permanently" delete them. Because the deleted items still exist, NetBackup includes them in the backup image. NetBackup displays these items when you browse the granular backup image and you can restore these items.
NetBackup does not support restoring mailbox items into tenant mailboxes in a multi-tenant Exchange environment. To recover items pertaining to a tenant mailbox, redirect the recovery to a non-tenant mailbox.
