This article is a couple of years old and I have already moved all of my precious data into the cloud. Because the flying spaghetti monster will save us all. Not.

...but I am still convinced this may be helpful to you.

Jesus saves. Buddha does incremental backups.

In celebration of World Backup Day, I hereby release my backup strategy.

Features[edit | edit source]

daily backup, fully accessible
compressed storage
block device encryption
speed

Requirements[edit | edit source]

external harddrive
modern linux kernel (use Arch Linux!)
current version of btrfs-progs (I have 0.19.20120110-2)
a strong password (you may follow this guide or similar)

Daily Routine[edit | edit source]

Wake up
Drink tea
Go shit
Exercise Yoga
Eat breakfast
Backup ALL the files (during hygiene)
Leave home

My external harddrive is totally occupied by a LUKS container. After connecting the drive to my laptop, I start like this:

 cryptsetup luksOpen /dev/sdb backup

If not happened yet, format the drive with a btrfs filesystem

 mkfs.btrfs -L backup /dev/mapper/backup

Then, mount it and use compression

 mount -o compress=lzo -t btrfs LABEL=backup /media/backup

If not happened yet, create a subvolume

 btrfs subvolume create /media/backup/nomaster

For may backups, I use rsync (with delete) to copy my files to an external hard drive. Vanished files will be deleted.

 rsync -aPv --delete --exclude downloads --exclude music --exclude .cache /home/nomaster/ /media/backup/nomaster/

After each sync, I make a snapshot of this state of my files.

 sudo btrfs subvolume snapshot -r /media/backup/nomaster /media/backup/nomaster-$(date +%F)

Lastly, I unmount the filesystem and close the container.

 sudo umount /media
 sudo cryptsetup luksClose backup

Then, I disconnect the drive.

When my drive will be full at some point in the future, I’m going to remove old snapshots to free space occupied by large files deleted a long time ago.

Initial Setup[edit | edit source]

I assume the external drive is /dev/sdb. If you have no idea about this, stop right now and come back when you know.

First, make sure, the external drive is clear to use. So mount it and have a look at the files if present.

Overwrite everything with zeroes.

 sudo dd if=/dev/zero of=/dev/sdb bs=1024

Format the drive

 sudo cryptsetup luksFormat /dev/sdb

(follow the instructions)

Open the crypto container

 sudo cryptsetup luksOpen /dev/sdb backup

Create a BTRFS file system

 sudo mkfs.btrfs /dev/mapper/backup

Mount it (with compression)

 sudo mount -o compress /dev/mapper/backup /mnt

Create a subvolume

 sudo btrfs subvolume create /mnt/nomaster # <- insert username here

Unmount, close and continue with daily routine.

 sudo umount /mnt
 sudo cryptsetup luksClose backup
