Raspberry Pi OS. Backup, Shrink and Restore to SD, USB or SSD. Raspberry Pi 400, Pi 4.
My favourite methods chosen from the many comments on my previous video. Thanks to everyone for their suggestions.
I wanted to do everything on the Pi in Raspberry Pi OS 32 bit. Gnome disks and Pi tools also write the image, I prefer Pi imager. Raspi config can expand the partition, I prefer Gparted
You can copy from the sd card to another device with sd copier in Raspberry Pi OS. I want to save an image to be re-written to the storage of my choice whenever I choose.
