"VSS Fast Restore" ("file-level") must do a byte for byte copy of the data. This means... it is completely dependent on the size of the files to copy. The larger the database and log files, the longer it will take. (Think of running the COPY command, or copying files using Windows Explorer.) "VSS Instant Restore" has a huge advantage over "VSS Fast Restore", especially in large Exchange environments because it uses the hardware-assisted volume-level copy. It does not need to get to the granularity of the file system... and it does not need to use operating system resources to perform the copy.
