Tapes aren't really archival, either, unless you have several copies. I've done batch recapture off of DV after a few years, and swore when I found serious dropouts. That's relatively low density data compared with LTO (though admittedly with less redundancy and error correction). After that, I dug around and found a copy of the captured files on some old hard drives, which unlike the tape, were intact.

So basically, from what I've seen, nothing is truly archival unless you have multiple copies, and if you have multiple copies, just about everything is archival, so the difference between tape and hard drives is that tape drives require a large up-front investment in a drive in exchange for cheaper per-TB costs for the media and higher physical density (because you don't have redundant electronics going along for the ride). If the per-TB costs aren't less and the density isn't higher, then tape offers no real advantage over spinning disks, IMO, unless your data storage needs are so massive that you have automatic libraries, and even then, only if you can't find a company willing to build a hard-disk-based librarian robot.

For home users, it is not a useful identifier because it usually changes regularly. For government users and business users, it is a fairly robust identifier, because most of those folks have static IPs (or at least fixed IPs assigned by a DHCP server).

Of course, there's not a 1:1 mapping between user and IP. So it would be more accurate to describe it as familially identifying information.

Sin is a perfectly reasonable social construct. The dictionary defines it as "Any reprehensible or regrettable action, behavior, lapse, etc.; great fault or offense." It is often used in the context of morals (another perfectly reasonable social construct), but not always.

Original sin is superstitious claptrap. The offspring of a heinous murderer is not, in any way, responsible or culpable for the acts of the parent via inheritance. Japanese and German nationals born after the end of WWII (and in many cases earlier) cannot be held responsible for the atrocities perpetrated by their ancestors -- the idea is fundamentally unsound.

Likewise, "Sinning before God" is utter nonsense. It carries all the significance and weight that "Sinning before the Easter Bunny" does. Both ideas gain only the weight that their communities, through delusion or disingenuity, care to arbitrarily assign to them. A good example is the assignment of sin to a person for wearing mixed fibers as a matter of theist dogma; it is purest meaningless claptrap. Delusion or disingenuity.

Mental health issues are not cut-and-dried.

Agreed. But racism is. When an animal is rabid, you put it down. It's not the animal's fault, but it's dangerous. With racism, you don't make excuses for the perpetrator -- you call it what it is and you don't encourage or make up reasons why it's ok -- it bloody well isn't ok, and it makes absolutely no difference as to why it's being put forth. Racism deserves zero social support, direct or indirect. Zero.

When mental illness foments, supports or creates hate and divisiveness, the situation has escalated beyond any reasonable level of tolerance. "Living with it" transforms abruptly from a kindness to abject stupidity. Even the very weakest grasp of history tells us that racism never, ever leads anywhere worthy, and that's the upside. The downside is absolutely horrific.

Try living with a serious mental illness for a while and then get back to us, mkay

Don't make baseless assumptions, m'kay? You'll spend less time savoring the taste of your own shoes, deluded into thinking that is the flavor of rhetorical success.

Yes, when you purposely try to take up as much space as humanly possible, it ends up being really big. The least you could do would be leave the raw images on your home media server and keep versions of them compressed to a halfway sane size on the laptop.

Why would I want to do that? I use Lightroom on my laptop for managing my photos. Doing it the way you suggest would A. be an unholy hell, and B. make it impractical to import photos in the field.

The ultimate horror for me, as a voter, is realizing that I may have to choose between Carly Fiorina and Hillary Clinton—between someone who nearly bankrupted one of the most profitable companies in the Bay Area and someone who seems to be hopelessly authoritarian in her positions on most issues—in effect, a choice between an incompetent Republican and an ultra-competent one.

Sorry, but you are not going to be lunking around HDs for backups after manually bar-coding, labeling, and cataloging them all for a decent sized business.

Most businesses don't have large storage needs. More and more businesses have users back up their desktop machines to a second drive (e.g. with Time Machine), store critical data on servers, and have IT people back up those servers. And just as many businesses outsource their email to Google, it isn't a big leap from there to outsourcing their server backups to any of the dozens of online backup vendors that are out there.

In the business side, some executives likes to believe that copies of data in different Datacenters are all you need for DR. It's cheap! This works great until you have a replicated corruption that you can't recover from and lose years worth of data.

A live mirror is not a backup. With that said, you can perform periodically rotating replication to multiple backup servers, and use that as a backup solution. That's no different than reusing tapes.

Consumers have mostly moved to external hard drives or cloud storage. I know everyone on Slashdot hates the cloud, but as a backup medium it isn't bad.

Oh yes, it is. It's fine for grandparents who just have a handful of files. For people who either take lots of photos or buy movies and music, it's terrible. Ever back up a 3 TB hard drive at 300 kbps? One backup takes 2.5 years. Even at ~9 Mbps (the U.S. average), it takes more than a month. Internet speeds are just not sufficient for backup purposes. They're two orders of magnitude short of being usable. We really need a nationwide fiber network with gigabit speeds or faster.

If you think 250TB of backup is a lot, then you don't need tape.

Need? Strictly speaking, no. But I'd be a lot happier being able to mail tapes for backup, rather than having to use fireproof hard drives locally. To fully back up my digital life once, I need somewhere on the order of 10 terabytes. I'd like to have several copies, so 50 TB would be convenient. That's 13 hard drives at 4 TB apiece. That takes up a fair amount of shelf space, and is very expensive to ship offsite. By contrast, if tape had kept up, I'd be able to store that data on five tapes, and I have plenty of room for five tapes and a single drive. And I could mail five tapes in a padded envelope.

And hard drives really don't work well for backups. You either keep them constantly spinning (in which case they are likely to be destroyed by the same power event that destroys the main drive) or you have to physically plug them in whenever you want to make a backup. This does not encourage folks to make backups regularly. Compare this with a tape drive attached to a computer, in which the media is effectively offline as soon as you switch tapes (and to some degree, even before). It's just an entirely different world.

On the other hand. I called a shop a while ago to see what they'd give for our 5x LTO4 tapedrives since we upgraded to LTO6 and they only offered us 30 euros per drive. So if you don't need the latest drive out there, you can save a lot of money by buying second-hand.

That might be what they would give you, but that's not what they'll sell it for. Assume that they'll resell that used drive for at least the equivalent of $500 U.S.
