In celebration of [http://ask.slashdot.org/story/12/03/31/1543200/ask-slashdot-its-world-backup-day-how-do-you-back-up World Backup Day], I hereby release my backup strategy.
 
== Features ==
 
* daily backup, fully accessible
* compressed storage
* block device encryption
* '''speed'''
 
== Requirements ==
 
* external harddrive
* modern linux kernel (use [[Wikipedia:Arch_Linux|Arch Linux]]!)
* current version of btrfs-progs (I have 0.19.20120110-2)
* a strong password (you may follow [http://www.thegeekstuff.com/2008/06/the-ultimate-guide-for-creating-strong-passwords/ this] guide or similar)
 
== Daily Routine ==
 
# 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 [[Wikipedia:Linux_Unified_Key_Setup|LUKS]] container. After connecting the drive to my laptop, I start like this:
 
  cryptsetup luksOpen /dev/sdb backup
 
Inside, there is [[Wikipedia:Btrfs|btrfs]] filesystem, I mount using compression.
 
  mount -o compress -t btrfs /dev/sdb /mnt/backup
 
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/ /mnt/backup/nomaster/
 
After each sync, I make a snapshot of this state of my files.
 
  sudo btrfs subvolume snapshot /mnt/backup/nomaster /mnt/backup/nomaster120331
 
Lastly, I unmount the filesystem and close the container.
 
  sudo umount /mnt
  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 ==
 
'''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
