When setting up database mirroring with snapshots, do you require a = completely separate physical server (the mirror server with the = snapshot) or can this server be another SQL instance on the same box?
Thank-you,

--=_NextPart_000_0012_01C8A463.A358EA10--A database snapshot always reside in the same instance as the source database. If the snapshot is of
a mirrored database, then it need to be in the same instance as your mirrored database.
A mirror database is always in some *other* instance than the source database. The two instance
*can* be on the same machine, but that is only useful for demo-purposes (as it won't give your any
added fault tolerance).
