+ + Configuration Backup to USB Drive +
++
Backing upyour Home Assistant configuration to USB. A good plus side is that you don’t need to mask all your passwords since the backup is locally at your home/residence.
+Requirements
+First you need a USB stick. Once you have one you need to prepare it to be used on your device.
+Once connected you want to format/work with the drive. To know what path it is in, you can check with dmesg.
# dmesg | grep sd

+Here we see we have a drive on /dev/sda1. We assume you created a partition on the drive to start with. This can be any type of partition. Preferred is a Linux filesystem type so you can set permissions!
Mount the drive (as root) to /media
# mount /dev/sda1 /media/
+Prepare USB Stick
+Change into it and create a folder called hassbackup and change the ownership to the user that runs Home Assistant. In my case group and user are both homeassistant.
# cd /media/
+/media# mkdir hassbackup
+/media# chown homeassistant:homeassistant hassbackup/
+/media# ls -al
+total 28

+drwxr-xr-x 2 homeassistant homeassistant 4096 Apr 29 10:36 hassbackup
+drwx------ 2 root root 16384 Apr 29 10:18 lost+found
+You can ignore ‘lost+found’.
+Install Dependency
+In order to preserve space on your drive we use zip. Install that too.
+/media# apt-get install zip
+Reading package lists... Done
+Building dependency tree

+Setting up zip (3.0-8) ...
+Install and run script
+Become the homeassistant user and place the following script to a place of your liking.
# wget https://gist.githubusercontent.com/riemers/041c6a386a2eab95c55ba3ccaa10e7b0/raw/86727d4e72e9757da4f68f1c9d784720e72d0e99/usb_backup.sh
+Make the downloaded script executable.
+# chmod +x usb_backup.sh
+Open up the file and change the paths you want to use, then simply run the ./usb_backup.sh.
$ .homeassistant/extraconfig/shell_code/usb_backup.sh
+[i] Creating backup
+[i] Backup complete: /media/hassbackup/hass-config_20170429_112728.zip
+[i] Keeping all files no prunning set
+Crontab
+In order for this to automatically make a backup every night at 3 am, you can add a crontab for it as the homeassistant user.
+Change below path to where you placed the usb_backup.sh and run the following line.
(crontab -l 2>/dev/null; echo "0 3 * * * /home/homeassistant/.homeassistant/extraconfig/shell_code/usb_backup.sh") | crontab -
+Auto mount
+This does not automaticly mount your USB drive at boot. You need to do that manually or add a line to your /etc/fstab file.
If your drive is on /dev/sda1, you could add a entry to your /etc/fstab like so:
/dev/sda1 /media ext4 defaults,noatime 0 1
+Manual step to mount the USB drive:
+# mount /dev/sda1 /media
