Spiffy! Now, as I'm studying to become an audio engineer, I wonder if
music labels will consider making the DVD the standard medium for
distributing "albums" at some point, or if they'll stick with CDs till
another innovation emerges. But, I digress ;)

I have seen some albums distributed as DVDs, years ago. Most people are
unable to hear the difference between CD-size sampling and DVD-size
sampling -- and I suspect most of those who claim to be able to are
fooling themselves.

I'm also wondering about the cost-effectiveness of using DVDs as
back-up media...

Not exceedingly great. Hard drives are big enough that effective backup
is becoming a big problem. To back up my server takes almost an entire
spindle of DVDs, and I've got only a small server. The ones at work?
Forget it.

IRL, probably the most effective means of backup is mirroring. Use a
RAID in the machine (so if you lose a drive you can replace that drive
and the RAID'll 'repair' the data onto the new drive), mirror the
contents of your server to another machine (preferably at another site),
mirror the machine contents onto an external drive and carry it to
another site, and so on.

DVDs are great for archive, as long as they don't degrade.

They are an immense pain in the ass for operational backup. Too many
disk changes to back it up (unless your server with less than half a
terabyte of store -- just a wee thing -- has a burner that'll handle
*100 DVDs at once*), and if you ever need to restore from it you'll be
there for *hours*, if not *days*, reloading data.

Tape? Tape can be doable if you're willing to shell out the sheckels to
get a good tape drive. Again, store is getting big enough this isn't
always feasible, and tape has been found to be startlingly fragile.

Really, the only practical means of operational backup is using drives.
RAID to protect against single-drive failure, removable to backup and
move offsite, or mirroring to offsite storage. Tape can be done if you
can get the speed and data density you need, but that gets *expensive*.


Mirroring is great for data redundancy, but archival is another
issue. Last time I was dealing with backup solutions, the company had
mirroring for data redundancy, and I whole heartedly agree it's the
only real solution at this time, drive goes out, you just pop another
in and on you go.

However they also had to maintain records of all transactions, so
basically had to have a backup of every file change, and they used a
very expensive tape solution for that. The HDs would fill up every
day with log files that had to be backed up and deleted just so the
system could have room to do it again the next day. It had about a
50% failure rate on trying to recover anything from it. It was
awful. Unfortunately there was so much data they would have been
going through so many hard drives it would have been prohibitively
expensive for the relatively small company, and required a large room
to store what fit on the tiny tapes. I still think they would have
been better off doing that though, but perhaps they had to do it for
legal reasons and just had to have a solution in place even if it
didn't work very well.

I'd certainly never recommend tape after that experience for anything
but archival data that you don't really care a whole lot about, but
then why bother with it at all, unless there was a legal reason to
have to make the backups.
