Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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.

Duplicity
I used this many, many years ago but switched to Borg[0] about five years ago. Duplicity required full backups with incremental deltas, which meant my backups ended up using too much disk space. Borg lets you prune older backups at will, because of chunk tracking and deduplication there is no such thing as an incremental backup.

What do you use for VPS backup? Would improved borg setup - pull mode - be enough? Or, do you use something else?
Currently, I'm auto-backing it up with borg (push mode) through wireguard tunnel to NAS behind ISP's CGNAT. The borg takes care of deduplication in SQL file, so incremental update (even in append-only mode) is very small for PostgreSQL dump.

Kopia: Open-Source, Fast and Secure Open-Source Backup Software
Borg 2 has been in development for nearly a year and a half [1] and may probably be released early next year, i.e., early 2024 (just a guess, seeing that even RC1 is not yet released and seems to have a lot of work to be done).
Does anyone know how Borg 1.x and 2 would compare to Kopia?
