You _are_ an idiot.
Demonstrably not.

Do you still have a 5.25" floppy drive connected to your computer?
How about a 10" mag tape drive?

Do *you* still have any useful data on 5.25's or tape? Anyone out there?

I stil have a functional Apple //e out in the garage with some stuff
on 5.25 floppies, but I haven't turned it on in years.

It's an accepted fact (for me anyway) that moving data to newer medium
is just part of the digital age. Apart from avoiding any alleged
problems with readers becoming unavailable (actually just LESS
available), the process of copying is a test of the data itself.

Some people believe that putting your data onto high-quality DVDs will
mean that the data are safe for the next half century.

Look at the cassette tape.

Do you have one of those connected to your computer?

The point is not what's being used,

No, that is the point. If you cannot get the data into your computer
then it matters not in the slightest if they're still on some media.

That's over 40 years for a mechanically quaint device. A much simpler
device such as DVD or BR disc

That's it. You've confirmed that you're an idiot who hasn't a clue.
Anybody who claims that a DVD is "much simpler" than a cassette is an
idiot troll.

It is of course much simpler.

Moron.

There's an interesting exercise - how many cards?

Take one 8MB - that's 8,000,000 bytes. Each card could hold 80 bytes.
Thus, 100,000 cards. Each box held 2,000 cards so that's 50 boxes.
At about 3.5 inches in height for each box that'd be a stack of boxes
175 inches high, or almost 15 feet.

And flash memory cards typically hold 500 such photos, making for a
small forest worth of paper. Enough cards to build a house.

LOL!!!

Don't forget the duplicate copy for the archive!

I have a similar arrangement, though there are multiple computers being
backed up. Each computer does an automated backup (Windows backup) to
the home fileserver (NSLU2 and USB disk) a couple of times a week, and
that's copied once a week to a portable drive that lives at work.

Of course, if you have a _really_ fast network connection and a
tolerant ISP you can just do your weekly archiving to a remote netork
drive.

:-)

Not practical at the moment. The NSLU2 transfer rate is about 5 MB/sec,
which is slow but tolerable. Our network connection to the outside
world is 5Mb/s (0.6 MB/s) incoming, and some small fraction of that
outgoing. It would take approximately forever to copy over a full set
of backups, and make the Internet connection nearly unusable in the
process.

Now, when someone starts providing fiber to the home, this might all
change.

Well, AT&T is rolling out its uVerse which is fiber almost to the
home, and Verison has its FIOS which is likewise, and Comcast claims
fairly high data rates, but all of them cost money, and lots of money
for lots of speed.

And in the case of AT&T the service support a couple of high def MPEG
video streams in addition to your phone and network access, so it's plenty
fast.
