1. Partition (disklabel gpt, add partitions as needed)

   sudo fdisk /dev/sda
   # g
   # n + defaults
   # p:
   # Disklabel type: gpt
   # [...]
   # Device       Start        End    Sectors  Size Type
   # /dev/sda1   2048 3906963422 3906961375  1,8T Linux filesystem
   # w

2. Format + tune + mount

   sudo mkfs -t ext4 /dev/sda1
   sudo mkdir /media/data
   sudo mount /dev/sda1 /media/data/
   sudo tune2fs -m 0 /dev/sda1 # no reserved blocks
   sudo vim /etc/fstab
   # UUID=f8b4c1a4-8189-49cc-86fb-c01c2a12b359 /media/data ext4 noatime,nodiratime,data=writeback,barrier=0,nobh,errors=remount-ro 0 1
   sudo vim /etc/dphys-swapfile
   # CONF_SWAPFILE=/media/data/swap
   # CONF_SWAPFACTOR=2
   sudo dphys-swapfile setup
   sudo dphys-swapfile swapoff
   sudo dphys-swapfile swapon

3. Install CrashPlan

   sudo apt-get install oracle-java8-jdk
   sudo apt-get install libjna-java
   
   wget https://download.code42.com/installs/linux/install/CrashPlan/CrashPlan_4.7.0_Linux.tgz
