.ptar a modern alternative to .tar.gz

[SansGuidon]

Hey,
I'm curious about this new format that brings improvements (reduced size, s3 native support) over tar.gz and I'm curious what you think about it.
Would it be beneficial to Cloudron users for backups? I believe we still rely on .tar.gz

And the tool has been extracted as standalone (isolated from the whole plakar thing)

First time I hear of this. Couldn't find a nodejs module.

It seems available only on their development branch, installable using go https://plakar.io/posts/2025-06-27/it-doesnt-make-sense-to-wrap-modern-data-in-a-1979-format-introducing-.ptar/
$ go install github.com/PlakarKorp/plakar@v1.0.3-devel.c7a66f1

I believe the requirement is mainly Go version 1.23.3 (via https://www.plakar.io/docs/main/quickstart/)
