Desktopfree

shrink-backup is a fast, rsync-based shell script that backs up single-board computers like the Raspberry Pi into minimal, bootable disk image files instead of full-size copies, with auto-expansion on restore. It's built for SBC hobbyists who want quick, storage-efficient backups independent of the OS running on the device.
