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.

Not openSUSE specific but what's the best backup utility?
I'm using rsnapshot. It's based on rsync. It's fully automated and I make daily and monthly backups backup to my NAS. The biggest benefit of rsnapshot is that it uses hardlinks. So only changed files are backed up. It doesn't have a GUI though, you have to set a configuration file.

Python Port of 600 Line Bash Script: rsync-time-machine.py for Rsync Backups
The description sounds like it does largely the same job as rsnapshot (https://rsnapshot.org/). What does yours do differently from rsnapshot?
- Redundancy and bit-rot protection on a single drive
- The fastest rm command and one of the fastest cp commands
- Do you perform offline backups for your NAS?
- Question: Backups anti ransomware
What are some alternatives?
