Hello,
I noticed, that the official dietpi images are quite compact and resize during installation to the full SDCard capacity.
As I’m having a 128GB SDCard, I would like to shrink my backup images as well.
Can you tell me how to do this?
Maybe there are also other ways to get a compact backup of the OS…
Thanks
Just a question: Are you creating real image *.img files? Or do you use dietpi-backup?
You should be able to generate a compressed DietPi image via the dietpi-imager script. This script is located in the .meta subdirectory in the GitHub DietPi share or can be executed via:
bash -c "$(curl -sSfL 'https://raw.githubusercontent.com/MichaIng/DietPi/master/.build/images/dietpi-imager')"
But this would require to have the SD card placed as USB connected device on another Linux box. It will not work on a running system as the script is simply not designed for this.
To get the partition resized on first boot, you would need to activate dietpi-fs_partition_resize.service before creating the image.
ok, would this solution work:
i create an additional data partition on the sdcard and before doing the os backup, i delete this data partition in gparted.
then I select the option "“Read Only Allocated Partitions” in the win32diskimager.
But I am not sure if this causes extra problems after writing it back to the sd card.
what do you think?
honestly I never tried something like this and I’m not sure if this will work or what side effects could occur.
I was using dietpi-imager
but now I see that it is gone, and I don’t see it anywhere… and I looked to see if there was a note as to why its gone, or alternative?
OPPS I see it now, its in
.build/images...
