The drives are shipped across the border, overseas etc. All the
fellows/ladies the other end can't be expected to all have matching
Raid setups. I'm not saying there isn't redundant backup, the data
isn't generally lost, I'm just describing some of the things that have
happened, all of which DOES support the use of Raid if practical.. One
is not going to have Raid backups of DVDs, again as you say.
Brings to mind one (true) story, a fellow was getting back to writing
an autobiography which he had set aside for several years.. Stupidly
he was not keeping backups. One day the Maxtor 30 gig in his P3
failed (you know how bad THEY are) Well, although two or three
chapters were lost, you know how I recovered his data? The book had
been started on an original IBM PC (the one predating the XT), with
the optional ($2000+) Shugart 6 meg drive. Although the computer was
long gone the massive hard drive had been removed and used as a
support for a bookshelf (seriously!) I got the original draft of his
book from that 1982 drive, Using a WD interface in an old XT I had
(with Edlin in/out commands,) Those IBM files had been converted to
WordPerfect 5 for his subsequent computer, a long-gone 486. I had to
convert that antique IBM format to Word. So Hard Drives CAN be used
for historical backups.
