Exchange VSS Writer failed restoring a backup to database '%1' because of a target log file path ('%2') and/or target system path ('%3') mismatch.  

The restore is being targeted to a different storage group than the database from which the backup set was originally taken. Under this scenario, both the log file path and system path must be targeted to a '%4' subdirectory under the database's log file path ('%5').
