This is also about making fun of the fact that government offices still use floppy disks.

Well, there are problems, but it’s not that they understand the content of the problems; most are just saying it at a level like “floppies,” which is outdated these days.

Is it paper tape?

Recently, tapes can record 18TB for 20,000 yen.

The theory that DAT is the strongest only applies to specific industries.

Was it a collaboration…?

>>12

Well, that’s why the anime version has episodes that are missing.

>>9

The decreasing demand for music and videos is misleading because the demand for tapes for data storage is actually continuing to increase.

>>10

A system that has the name “whale” must be difficult to back up…

Tape regression is coming quite seriously, you know…

This is what was spinning around in the computer room of old anime.

Although stone can be preserved for thousands of years…

I thought it was a collaboration like from an old era, but it’s actually a very current story.

It seems like there is still room for growth, that’s amazing!

Well, if you’re motivated, I can cover the anime I’ve recorded on tape too.

One reason for the gradual disappearance of HDDs, which are caught between the issues of reliability and cost per capacity of SSDs and magnetic tape…

It’s impossible to use a single disk for this kind of application in terms of speed, and that’s just a pretty good excuse.

Are you doing head starts with loading…?

It must be engraved on a stone tablet.

Wasn’t the physical size of tapes larger in relation to their capacity?

Is it just an image, or is it really not like that?

>>26

It’s big, but the other benefits outweigh that.

>>26

For places like companies or data centers that can provide vast land, other advantages outweigh the costs.

For individuals, there isn’t enough data that would need to be recorded on tape, so the benefits of tape may be low.

It’s perfect for keeping data that you don’t usually use but have to save.

I always think it’s better to stop stating capacity and speed based on compression when there is so much data that is not suitable for compression in this age.

The tape itself is cheaper than an HDD, but the drive costs around 1 million yen, so it’s unaffordable for individuals…

>>30

What are individuals backing up so much for?

I wonder what the loading speed is like.

>>32

Random reads are finished, but sequential reads are faster than HDDs.

LTO will always be active.

The standard has been upgraded, and it also has backward compatibility.

https://ja.wikipedia.org/wiki/Linear_Tape-Open

Do you read from left to right?

>>37

Normally from right to left.

I’m using the technique commonly found in manga that “expresses foreign languages in horizontal writing.”

All the speech bubbles are in horizontal writing, so it’s hard to read.

The difficulty of using tape-based backup software.

SAVE THE WHALE (Save costs)

From a security perspective, floppy disks are far more robust than those that use USB ports.

It seems that there was a conversation suggesting that floppy disks may have the advantage in places where security is the top priority and capacity or efficiency are not particularly needed.

There are applications where tape is favored as shown in the image, as well as applications where disk is favored.

Currently, both demands are expected to continue, so we have no choice but to keep producing both.

SAS HDD for businesses is already approaching the same cost per capacity as SSDs, so it will soon perish.

I only have the image of backups being taken every day for banking purposes.

They are nice guys.

The disk only lasts for 5 years!?

>>49

There was a time when, for some reason, I would die almost immediately.

Does it turn out to be around that if you take the average?

>>51

About 10 years ago, when Google took statistics on their own HDDs, it seems they found that it would be better to consider replacement after about 5 years.

The tape only has one-way data mapping… When it comes to reading, it suddenly becomes a mess.

Hmm, it seems that the Science Special Investigation Corps and the Ultra Guard are not entirely retro-future either.

The reason why magnetic tape is valued is that

The biggest issue is that it’s easy to see when the data has been tampered with or modified.

When data submitted to the media during the trial is provided on magnetic tape, it also increases in priority.

Is there any way to reduce the cost of introducing tape at home…?

>>57

If you’re using it in a typical household, isn’t a disk sufficient?

I’m on the tape backup side, but there aren’t enough manufacturers left to choose from.

The tar command, familiar in Linux and recently also available on Windows, is…

Abbreviation for Tape Archive

There is something that connects to the theory of FAX.

Even now, in information-related texts, the topic of backup often concerns magnetic tapes…

People who are not good with IT often tend to want to use new technologies and underestimate analog methods.

Speaking of that, I think there was a case where Resona messed up the tape backup.

Tape media has an appearance that gives off a strong sense of trust.

Moreover, this loading itself is something that can be easily done on a computer, right?

VHS often gets moldy, but I wonder if companies have proper measures against mold for their backups.

Tape? Is tape that magnetic tape?

Really?

I like the person next to the 30-year-old comic with a deep and flavorful face.

Jeff’s reaction is so intense that it seems really fun to teach him something.

However, if a powerful magnet comes close to the tape, everyone will die.

>>72

Isn’t it just a matter of prohibiting the entry of magnets there?

If they are using tape for backups, it must be a company of a certain size.

>>88

It’s the same for any medium that if someone intends to destroy or leak it with malicious intent, it’s not impossible.

In terms of security, becoming more analog does not change the fact that it is relatively excellent.

I get nervous wondering if I can really rewind from the tape.

It worked out well…!

It is often thought that tapes have disappeared because they are no longer seen at the corporate level due to the difficulties of maintenance.

It was a world I knew nothing about.

>>75

In industries you don’t know, even common knowledge is fresh and interesting, right?

The junior was called in to completely replace the cartridges.

I haven’t done it, but it seems a bit fun.

I used to use it.

I moved everything to the cloud and no longer use it.

In the end, what remains is physical media, and it’s also more secure.

The hardware and software both have a high price impression.

There was a problem in the advanced information exam that calculated the number of tape drives needed based on the amount of backups per week.

I heard that there are cases where data can be saved by sticking together even if the tape is cut.

In terms of security, it ultimately comes down to analog being the strongest.

>>85

In the end, humanity has not developed a medium with durability surpassing stone tablets in about 4000 years.

>>89

Records made with quartz for ultra-long-term storage periodically become a topic of conversation.

This time the cost is outrageous.

Doesn’t tape take up space?

Or is it because overseas has vast land, so even if you take up space, it doesn’t matter?

>>86

I won’t say it doesn’t take up space, but…

This is typically used in places where large refrigerator-like servers are lined up.

If it’s just tape, I won’t have much trouble finding a place to put it.

I prefer not to use new technologies unless required, as older technologies tend to be more reliable.

Isn’t the stone tablet amazing…?

>>95

The stone monuments from the Edo period are surprisingly hard to read now, aren’t they?

The Jizo statue is in a serious situation.

It’s fun to watch the tape changer in action, isn’t it?

I thought when you said “tape,” you were talking about DAT tapes.

Is there such a thing as LTO9 now?

I’ve only used it up to about 4.

In Japan, what has the strongest preservation is wood boards, bark, or paper?

>>98

Because I don’t have that, regular transcription is necessary…

>>98

Because disasters can cause power outages or physically damage systems, not just due to simple years.

It can be said that paper culture will not disappear anytime soon for the sake of preservation, or rather, it cannot be eliminated.

When you first enter DC, it’s exciting, isn’t it?

The sound of the intake and exhaust from the neatly lined-up racks is overwhelming.

The presence of both talismans and a god shelf, along with the fusion of science and magic, is nice.

>>99

When I saw the supercomputer at the RIKEN open house, I was amazed to see an entire rack dedicated to LTO changers!

>>108

This is definitely something that gets you hyped up!

I’m envious…

Does humidity also affect stones?

I recall hearing in the past that the computers in spacecraft and such are low-spec because they use code and parts that prioritize reliability above all else.

>>103

The condition might necessarily be that it has dry parts with ten years of operational performance.

There are also cases where such advanced calculations are not necessary.

>>111

Difficult calculations can be done on the ground, so we only need to send the results.

The deterioration of disk media, which is becoming a serious issue even in retro games.

>>104

LD using acrylic resin has a short lifespan of 30 to 50 years.

CDs and DVDs made of polycarbonate are said to last between 50 and 100 years.

Even if the disk itself is intact, the recording surface can die in 10 to 20 years…

I saw something about Lithuania or some country promoting the digitization of various documents because they don’t know when they might be invaded, and it made me a bit down.

Well, it’s true that the black boxes on airplanes are all tape too…

It probably will disappear because there’s no need to keep it, but if we were to save all the responses on these obscure message boards, it would amount to an incredible volume.

If left unattended, books can be eaten by silverfish and become tattered, but if you untie the bundle and do maintenance like sun-drying, they can last for several hundred years.

Foreign books have become prone to deterioration due to acidic paper (now they use neutral paper, so it’s fine).

It’s okay to have the good parts in analog.

In the infrastructure SE field, there are probably some people who have never entered a data center and don’t have plans to do so.

Personally, I think it would be better to go in just once and see the real thing.

>>115

It’s especially true for cloud-native.

Defecating in the server room is now a cultural phenomenon of the entire era…

I can’t stand using a dried-up, stable medium that is both fast and has a large capacity.

I’ve heard that the sense of a base being located in such an ordinary building is the climax of DC.

Even if it’s called cloud, it’s just that the cloud provider is operating the data center.

I heard that LD is starting to die.

I don’t want an all-time poop culture.

10 to 20 years seems like more than enough! But 10 to 20 years really goes by in the blink of an eye.

Has it been over 40 years since the Famicom?

There was a card covered in tiny text that was finally readable with a primitive microscope, but now I feel a strange ratio of romance to practical possibilities.

>>124

Even if it didn’t go that far, there were often stories in sci-fi where characters went to libraries to read microfilms.

I wonder if they are still making it…

There are quite a few DVDs that can no longer be read, right?

The sound of “tape” feels outdated, which is not good.

In 30 years, it’s not uncommon for the data to have already gone through 2 to 3 cycles of rewriting.

Although MO was quite excellent in reliability and read/write speed, it quickly perished.

It’s interesting to take the AWS certification exams.

Cheap storage can retrieve data in 12 hours!

Is the SSD strong?

>>131

Weak weak

Because I joined before the pandemic, I was able to visit the data center and participate in training while actually handling the equipment.

The new graduates who joined during the COVID period had never even seen L2 and L3 switches in remote training, and it was quite tough for them.

It’s not that I have to deal with it for work, but it seems I still can’t quite grasp the image.

It is said that NAND flash can reliably read data that has been written for about a few years, so current SSDs cannot be used for long-term storage.

Improvements in this area are likely progressing rapidly, but we are still far behind.

This thread seems quite serious…

The era of non-volatile memory will still largely be dominated by NAND flash, and I hope something can be done about it.

I quite like when a proper topic is established and the thread progresses with a proper discussion.

I’ve never seen a machine that spits out long paper like in old movies in real life.
