- Connected one of the solid-state drives to c1vac. It was /dev/sdb.
- Formatted the drive using
sudo mkfs -t ext4 /dev/sdb
- Mounted it as /mnt/backup using sudo mount /dev/sdb /mnt/backup
- Started a tmux session for the dd, called DDbackup
- Started the dd backup using
sudo dd if=/dev/sda of=/dev/sdb bs=64K conv=noerror,sync
- Backup completed in 719 seconds: need to test if it works...
controls@c1vac:~$ sudo dd if=/dev/sda of=/dev/sdb bs=64K conv=noerror,sync

- Generate a bootable backup hard drive for c1vac, which could be swapped in on a short time scale after a failure.
