No. Only for the reason that you don't have a full backup
of everything on stable, offline media. On the other hand,
you do have a working backup of the media on the disk that
is being removed. Why just just up the scsi address, write
lock it and use the drive as its own backup? Basically you'd
add the new drive in where the old one was in the chain,
up the address of the old one -- total time 15 sec if you
don't drop the jumpers too many times -- and copy the contents
of the old drive to the new one.
