Requirement

sudo apt install partclone

Create File to Hold ISO

mkdir /media/mruckman/RUCKMANS-4T/ISO
touch /media/mruckman/RUCKMANS-4T/ISO/IDEAPAD330.ISO

The following wild card names might be slightly different depending on your backup

sudo cat /media/mruckman/RUCKMANS-4T/2021-07-07-01-img/sda2.ext4-ptcl-img.gz.* | sudo gzip -d -c | sudo partclone.restore -C -s - -O /media/mruckman/RUCKMANS-4T/ISO/IDEAPAD330.ISO

Now to Finish Preparing the ISO Image

cd /media/mruckman/RUCKMANS-4T/ISO

# Answer Yes when prompted to Abort
e2fsck -f IDEAPAD330.ISO
resize2fs -f IDEAPAD330.ISO

Mount the Image in Read-Only to Retrieve Files. When mounted, it's read-only and can be found /mnt

Note: Mount Utility only seems to work on local drive and NOT external drive

sudo mount -o loop -t ext4 /media/mruckman/RUCKMANS-4T/ISO/IDEAPAD330.ISO /mnt

Unmount the ISO Image

sudo umount /mnt
