Thanks Erland - worked a dream!
I am working through my 70-431 course, and this was mentioned a number of
times. However, I see no point in doing this.
Consider:
I take snapshots hourly, on the hour.
At 1.10pm, someone admits a major blunder, and tells me they dropped a table
at 11am.
I can now restore the 11am snapshot to a new DB and recover the table.
But, to do this, I need to delete the other snapshots.
This means that any other "blunders" cannot be recovered from snapshots.
Surely this is not an effective solution?
In fact, the only real use for snapshots I can see, is
To make a snapshot of a mirrored / log shipped database so it can be used as
a static report DB, OR
To make a quick "backup" where a DBA needs to do some work quick and might
risk dataloss through an error.
