Performing instant recovery (Exchange Server)
Before performing instant recovery of a Microsoft Exchange Server backup:
The DS-Client service account must be run under a local administrator account and have write access to the instant recovery vault.
The Microsoft Exchange Server must be running and configured with sufficient credentials to operate in the Windows domain of the database server so that it can accept the data from the instant recovery vault.
The destination Microsoft Exchange Server must have the same domain name and Microsoft Exchange Server name as the backup source.
The instant recovery vault can reside on the original Microsoft Exchange Server or a dedicated Microsoft Exchange Server. The path to the instant recovery vault must be unique to each DS-Client.
To perform instant recovery of an Exchange Server (VSS-aware) backup:
1. Click the Backup Sets tab.
2. Select the backup you want to instantly recover.
3. On the Restore menu, click Instant Recovery.
4. Select a backup session, and then click Next.
5. Select the components to restore, and then click Next.
6. In the Share name box, type the share name that is used to connect to the instant recovery data. Users must map to this computer and this share to access the data.
7. Click Finish.
NOTE:  After an instant recovery share has been activated, you can use the files to recover the database and mount it to the Microsoft Exchange Server. For more information, see the Microsoft Exchange documentation.
