In this scenario, I create an encrypted LUKS disk to periodically save the Documents/ folder with Rsync, from a computer that does not have a GUI.
Creating a LUKS Disk
# Snapshot the disk list
BEFORE=$(mktemp); lsblk > "$BEFORE"
# [PLUG IN DISK]
# Snapshot changed disk list
AFTER=$(mktemp); lsblk > "$AFTER"
# Show the disks changed
diff -U0 -w "$BEFORE" "$AFTER" | tail -n +4
# Remove tmps
rm "$BEFORE" "$AFTER"
# Setup luksFormat Disk
sudo cryptsetup luksFormat /dev/xvdj
# [TYPE "YES"]
# [Enter Password]
# [Enter Confirmation Password]
# Open Encrypted Partition
sudo cryptsetup luksOpen /dev/xvdj DATA
# Install XFS Tools is necessary
sudo apt install xfsprogs
# Add XFS File System
# (sudo apt install xfsprogs)
sudo mkfs.xfs /dev/mapper/DATA
Mounting a LUKS Disk
# Attach disk to Qube
# Replace xvdi, DATA with actual names
sudo cryptsetup luksOpen /dev/xvdi DATA
# See drive on mapper
ls /dev/mapper/DATA
# Create mount point
sudo mkdir /media/user/DATA
# Mount the partition
sudo mount /dev/mapper/DATA /media/user/DATA
# Rsync ~/Documents, excluding node_modules
sudo rsync -av --exclude="node_modules:*.un~" ~/Documents /media/user/DATA
Unmounting a LUKS Disk
# Unmount the disk
sudo umount /media/user/DATA
sudo rm -r /media/user/DATA
# Close the encrypted partition
sudo cryptsetup luksClose DATA
