How to Get Your Backup to Half of Its Size – ZSTD Support in XtraBackup
lrzip
Long Range ZIP or LZMA RZIP
https://github.com/ckolivas/lrzip
"A compression utility that excels at compressing large files (usually > 10-50 MB). Larger files and/or more free RAM means that the utility will be able to more effectively compress your files (ie: faster / smaller size), especially if the filesize(s) exceed 100 MB. You can either choose to optimise for speed (fast compression / decompression) or size, but not both."

File compression
7zip and XZ are almost always the best in any comparison. (They use the same algorithm.) Occasionally something new comes allong that may be bettyer, but it fades away... Like lrzip. https://lkml.org/lkml/2011/6/4/23 https://github.com/ckolivas/lrzip

If we found a way to reverse a hashing function, would that make them ultra-compression algorithms?
For example lrzip has an intense "dupe hunting" mode and takes days for large content, but does compress very well once it's done (and expansion is fast). I use it on long term storage backups and disk images and junk. Completely incompatible with streaming, unlike chunk-based like gzip or deflate or etc, although unpacking can stream such as searching or verifying a tarfile archive. But the original source has to be file-based so seeking for the hunting can work across the entire file-as-a-block.

Ask HN: How would you store 10PB of data for your startup today?
Best I know of for that is something like lrzip still, but even then it's probably not state of the art. https://github.com/ckolivas/lrzip
It'll also take a hell of a long time to do the compression and decompression. It'd probably be better to do some kind of chunking and deduplication instead of compression itself simply because I don't think you're ever going to have enough ram to store any kind of dictionary that would effectively handle so much data. You'd also not want to have to re-read and reconstruct that dictionary to get at some random image too.

Ask HN: What is your approach for managing personal digital assets?
I religiously use Google contacts. It's the simplest way to keep people contacts up to date on Android.
I archive all important documents in specific folders by subject and date. This is backed up to back blaze with restic. https://restic.net/
I use https://ente.io for pictures. I convinced my wife to use it, and she agreed to auto share her photos so I don't nag her for copies. It had simple import from Facebook and Google.
I also keep extensive journals, which really helps to tie it all together. I can basically grep for hangouts, conversations, etc.
I also separate work journal from personal, and have essentially a journal for each project. https://jodavaho.io/tags/bullet-journal.html for how.
I religiously use Google calendar for all plans, you can easily search it for past events to get dates.
I also use monicahq for some notes about things I should remember about people but the habit never stuck.

Duplicity
After Borg, I switched to Restic:
https://restic.net/
AFAIK, the only difference is that Restic doesn't require Restic installed on the remote server, so you can efficiently backup to things like S3 or FTP. Other than that, both are fantastic.

I'm curious, too. I know they've had some issues in the past:
https://github.com/restic/restic/issues/3268#issuecomment-78...
On the other hand, I tested around 15,000 backups last year (multiple hourly backups, daily tests) and they all passed.
