How I archived 100 million PDF documents... (Part 1)
After a quick Google search, I figured out that only less than 1% of ancient texts survived to the modern day. This unfortunate fact was my inspiration to start working on an ambitious web crawling and archival project, called the Library of Alexandria.

What do you mean by storage system? Just curious because I'm working on a similar project.

Anyone here with 50TB,100TB+ of personal storage that isn't mostly movies/TV/porn ??
I'm collecting documents. Working on an app suite called Library of Alexandria. Got 91 million docs atm (mostly PDFs) and it's only going up. All of that fits on around 100 TB with gzip compression.
- Archive for software / comp sci books / ebooks?

Good document classification library in Java
I'm working on an OSS called Library of Alexandria. It is an application that is built to collect, archive, and make searchable various (mostly PDF) documents. I have a little bit more than 90 million documents archived. My next step is to somehow label/classify them.

I was wondering what y'all hoarded on your epic setups. I use only one NAS containing 2.8 TB of my personal data. Looking forward to seeing what you hoard.
90 TB of PDFs. I'm working on the Library of Alexandria project. Just a fun little library, nothing more. 😅😅😅

Does epub compress well?
You should look at Precomp - an apparently abandoned, but awesomely working arhiver that is dedicated to compressing those ZIP-based formats, and compresses them twice-thrice as small as LZMA2 can.
- Any suggestion for compressing a large batch of photos and videos into a single zip?

Putting 5,998,794 books on IPFS
You can also have a look at this packer. It compresses PDF and EPUB 2-3 times smaller than 7z at maximum settings, at half the speed. I keep all my books in it and never had a problem.
- .bin compression

libgen currently adds around 1,300 books a day
There is an opensource archiver called precomp that is designed specifically for e-documents and compresses them 2-3 times smaller than 7z in ultra mode. It works, and I keep my e-books in it. However, it seems nobody else does, and development has stopped due to lack of interest.

AWS switch from gzip to zstd – about 30% reduction in compressed S3 storage
There are tools like preflate [1] or precomp [2] that guarantees a bitwise identical reconstruction, of course modulo bugs.

Which compression method for archiving OS ISOs?
You may use "precomp" in order to seek and uncompress those parts. Then you can use a better compression algorithm : http://schnaader.info/precomp.php

Is there any research as to what's the best way to compress each file type?
Precomp http://schnaader.info/precomp.php is a program which will seek compressed parts and decompress those parts in order to compress with another algorithm. This greatly improve compression ratio with the other algorithm.
