Hello Jeffrey734,
Thank you for your feedback. I believe .zst support can be added to PiSafe.
I am glad to hear that using the "no compression" option works for you for now. That is precisely why I put it in.
I will take a look at adding .zst.

Hello Jeffrey734,
The latest beta (1.2.5-j) has support for .zst. It also now only installs gz, xz and zst on demand.

Hello Jeffrey734,
The latest beta (1.2.5.m) supports .zst. You can edit the settings file (pisafe settings) and change the compression_level line to "compression_level=22 --ultra" with no quotes to get ultra 22.
I ran a bunch of benchmarks and found xz (9 -e) better on a pi4 with 8gb ram. See below:
