Well tapes have a measurable life expectancy also and tape drives have
moving parts.
So you have one limitation on top of another. Disks are your best
method. Especially SCSI.
Our backup scheme here is: we backup to a separate disk every night,
copy that backup to tape,
and finally send the backup to a remote disk. Thus we have multiple
copies and no single point 
of failure.
