In need of crazy compression
mcm 0.83 : https://github.com/mathieuchartier/mcm/tree/v0.83
- Is there any research as to what's the best way to compress each file type?
- Don't Use RAR
- Is 7zip with lzma2 the best tradeoff between compression speed and decompression speed?
-
Help me out with some compression tips
A good trade-off is mcm : it uses SSE2 and MMX. It is not as good as zpaq, but it is better than LZMA2 (7zip) and really faster than zpaq. https://github.com/mathieuchartier/mcm

Best archival medium for 3-10 gig video files?
An alternative is including PAR2 files.

Understanding CD-R and CD-RW (2003) [pdf]
Not only that but if you budget for an expected error rate of let's say 10% you can use par2 to create additional files that add that redundancy to your archives.

Side-by-side: WinRAR, PeaZip, 7-Zip, WinZip
That's the same reason I do archive files. For parity I personally use (https://github.com/Parchive/par2cmdline) which does create extra files, so I can see how WinRAR would have something to add there.

FSArchiver – Filesystem Archiver for Linux
Here's the first example I could find.
https://pthree.org/2014/04/01/protect-against-bit-rot-with-p...
Basically, you take a normal TAR file and creates external parity files that can be used to recover data in the case of bitrot. Something like this would have been great to have on a few data files I had to retrieve from tape that ended up with a bit flip somewhere in the network > disk > tape > disk process.
However, it doesn't look like the program is maintained anymore...

The last release was in 2004 (Wikipedia says it was active until 2015, but I don't see that).
