NetApp snapshots are VOLUME LEVEL ONLY.  From a NetApp snapshot, you can restore single files (although this varies based on the implmentation).  

You WANT volume level snapshots.  It allows you to stagger your backups and shortens your restore times, improves performance, etc.  And when you get into application data such as SQL and Exchange, you'll use different snapshot and backup methods that don't work well together.

The ability to create aggregate snapshots does, in fact, exist since at least ONTAP 7.0.  They can be managed from the filer console using the normal "snap" commands with an "-A" switch, but are not readily manageable using FilerView.  The extended snapshot access features (.snapshot folders using CIFS or NFS, and Windows Shadow Copy client functionality) do not appear to work with aggregate snapshots, so you won't have direct access to the individual files from your client.  You might be able to restore individual files using the "snap restore" command and the "-file" switch (a single file snapshot restore).

Most people view the scheduled aggregate level snapshots as a good "last resort" backup, and might initiate a manual aggregate level snapshot in preparation for a major system upgrade (such as an ONTAP version upgrade).  Also, since standard utilities (like SnapDrive) give a disgruntled or misguided administrator the ability to destroy volume level snapshots (without specific rights on the Filer), they provide an additional level of data security.
