Microsoft does not support the restore of Public Folders to a Recovery Storage Group in Exchange 2007, therefore the restore of the public folder database in Exchange 2007 must overwrite the existing database or go to an alternate server.
Per Microsoft, in Exchange 2007 only mailbox databases can be restored to an RSG: http://technet.microsoft.com/en-us/library/bb124039(EXCHG.80).aspx
When You Should Not Use a Recovery Storage Group
RSGs are not appropriate to use under the following conditions:
- You have to recover public folder content. Only mailbox databases are supported.
- You have to restore entire servers, one storage group at a time.
- You have to restore databases from multiple storage groups.
- You are in an emergency situation that requires changing or rebuilding your Active Directory topology.

2. In the console tree, expand Server Configuration, and then click Mailbox
3. In the results pane, select the server on which the Public Folder database is located, highlight the Public Folder under the appropriate Storage Group.
4. In the work pane, click Dismount Database.
5. A warning appears asking if you want to dismount the database, click Yes.
6. In the work pane, click properties.
