Pishrink with openhabian

[ruebox]

Hallo there,

I would like to secure my openhabian image and compress it with pishrink (GitHub - Drewsif/PiShrink: Make your pi images smaller!)

Does anybody of you have experience with pishrink and openhabian with openhab3?

Thanks for your response.

I haven’t used it, but I’m also interested. I’ve been using 32GB SD cards and would like to move my current system to a 16GB card without starting from scratch.

I was thinking of setting up a separate Raspbian Desktop system so that I can use the built-in SD Card Copier to move from the 32GB to the 16GB card.

i use openhabian with openhab 3.3.0.m2 and i use a little script for my backups what i start manually from time to time, most before doing updates.

some time ago i had oh system installed on a ssd, this was 120gb, there i started using pishrink to avoid having always 120gb big backups. acutally i am back on a sd-card, but also use pishrink to receive backups as small as possible. thats the reason i have both versions (ssd and sd) in my script, ssd is commented out.

I wouldn’t mess with this. You are just about to very likely break anything.
Just export your config, install to another (smaller) SD from scratch, and reimport.
