Subject: dd backup of c1vac made 
  1. Connected one of the solid-state drives to c1vac. It was /dev/sdb.
  2. Formatted the drive using sudo mkfs -t ext4 /dev/sdb
  3.  Mounted it as /mnt/backup using sudo mount /dev/sdb /mnt/backup
  4. Started a tmux session for the dd, called DDbackup
  5. Started the dd backup using  sudo dd if=/dev/sda of=/dev/sdb bs=64K conv=noerror,sync
  6. 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.
