I want to be able to boot into alternate setups to protect against a undesirable upgrade or otherwise test a new setup

$ sudo parted -l
Model: ATA SAMSUNG HD204UI (scsi)
Disk /dev/sda: 2000GB
Sector size (logical/physical): 512B/512B

$ df -h

I mounted with

sudo mkdir /sdb6
sudo mount -t ext4 /dev/sdb6 /sdb6/

and I copied files with

sudo time nice -19 rsync -v --archive --delete-during --hard-links \
 --numeric-ids --exclude /proc --exclude /sys  --exclude /var/tmp \
 --exclude /tmp --exclude /storage  --exclude /dev  \
 --exclude /lib/init/rw --exclude /mnt --exclude /cdrom \
 --exclude /media --exclude /sdb6 / /sdb6/.
