Create the RSG Database
Next, create the recovery database with New-MailboxDatabase . The MailboxDatabaseToRecover
parameter is what links the RSG to the target database. Figure 8 - 4 shows the results of the following
cmdlet that creates a new RSG:
New-MailboxDatabase -MailboxDatabaseToRecover “Mailbox Database” -StorageGroup
mb100\rsg -EdbFilePath c:\rsg\rsg.edb
< rsg new db.tif >
Figure 8-4
If needed, mark the mailbox database to allow overwrites. Setting this value to true allows a database
that does not match the information in Active Directory to mount. Forcing administrators to explicitly set
the database overwrite flag prevents accidentally mounting an incorrect database.
Set-MailboxDatabase -Identity “mb100\RSG\mailbox database” -AllowFileRestore:$true
Restore the Database
Restore the database file from tape or disk. Selecting the Last Restore Set checkbox means that after the
file restore, Exchange will perform a hard recovery. Figure 8 - 5 illustrates the database restore options
when using the System Backup utility. Exchange automatically redirects any restores to the RSG instead
of the original location.
