Hi,
I think that you should evaluate if the downtime associated to the disk
failure is acceptable. In this case you have to wait for a new disk and
recover the db. If the customer can tolerate this for me it's ok (you
are getting some extra work, but this is not necessarily bad).
Please also consider that modern SCSI disks (usually) are at least 36GB
so you could apply the same considerations to db bigger than 3gb.
just my 2 cents,
Giovanni
P.S. I assume the db is in archive log mode.
