Is there a GUI app on #Linux I could use to clone a disk (i.e. SD card) to image? I know there's dd but that isn't GUI. I normally use and prefer #KDE's Partition Manager which I could use to just copy over each partition from a disk to another, but copying the disk as an image would be far more portable - I know on #Windows people use Win32 Disk Imager, while on #macOS I think you could just use the built-in Disk Utility.
Update: WAIT - I think you could actually do this on KDE Partition Manager! Just mount the disk, right click the partition, click Backup, set an output path, and apply.
There's also an option to Restore a partition on the app, which I assume is when you then supply the image you had just backed up. I'm testing this right now, but I'm hopeful!
Update 2: It worked perfectly. I backed up the partition as an image (not sure if you could do so for multiple partitions in one image), and restored it on another empty SD card.
I tested it on an #OnionOS install for my #MiyooMini. After the restoration was done, put in my new (target) SD card, and the device literally booted right into the game I had paused right at the time when I removed the (source) SD card. KDE Partition Manager ftw.
