I guess we have to look at disaster recovery, when it comes to
tapes, in order of priorities. So, if we're
talking about your most critical applications nowadays -- your
most critical data -- tape
backup is actually losing favor to
disk backup or data replication.
@24666 That said, we always have to keep in mind that not all
data is created equal and is not as critical as others. Tape still
has a very good place in the DR scheme of things just because of
its low cost and ease of portability to send it offsite. I would
not consider tape a thing of the past just yet -- it's still very
useful. But, because of its relatively limited performance, and
also at times the inability to acquire the tape rapidly, it's more
suited for lower criticality or lower priority applications or data
that still have to be recovered in the event of a site-wide
disaster.
So, I'd say tapes are still very current, and until we find
cheap, cheap, cheap, cheap disk, they're still very much in
fashion.
