PiExt

PiExt (Linux): Creates and restores compressed images of Linux EXT2, EXT3 and EXT4 partitions, including the boot partition and MBR.

PiExtRestorer (Windows): Restores PiExt images directly under Windows.

Both applications provide a graphical user interface (GUI).

Instead of storing the complete filesystem partition, PiExt stores only the sectors currently used by the filesystem. The data is compressed on the fly using Zstandard (ZSTD). The MBR and BOOT partition are stored separately.

The first image created in an image folder automatically becomes a Base Image. Further images are created as Differential Images based directly on the Base Image.

Supported Platforms:
Linux: Image creation and restoration with PiExt
Windows: Image restoration with PiExtRestorer
