-title: "Automatic SD Card Backer Upper"
----
-
-I play on my DSi a lot, and i have all of my cartridges dumped to an SD card
-so I don't need to carry them with me to switch games. All my saves are stored
-on the SD card too, and sometimes I worry about the card getting corrupted or
-lost. So I used my Raspberry Pi to easily back it up. All I have to do is plug
-the card into the Pi, and it copies the files into a new folder and toggles a
-light when its done.
-
-## What I used:
- * SD Card adapter
- * USB mouse that I didn't care about
- (any usb device that can light up will work)
- * Raspberry Pi 3
- (any raspberry pi with a USB connection and 3.5mm jack will work)
-  
-I did this on Ubuntu, but the instructions should work for Raspbian as well.
-
-## Files
-
-I made a few files for this to work: a udev rule file, a systemd unit, and a
-shell script.
-
-# Udev Rule
-```
-# /etc/udev/rules.d/999-automount.rules 
-ACTION=="add", SUBSYSTEM=="block", ENV{ID_SERIAL_SHORT}=="000000000828", RUN+="/usr/bin/systemctl start DSi.service"
-```
-You'll have to modify the `000000000828` to match the serial of your device,
-which you can get by plugging in the device, finding its /dev file, and running
-`udevadm info /dev/sdx | grep ID_SERIAL_SHORT`.
-
-# Systemd Service
-```
-# /etc/systemd/system/DSi.service
-[Unit]
-Description=back up dsi sd
-[Service]
-ExecStart=/home/ubuntu/autocopy.sh
-[Install]
-```
-There's nothing in the `[Install]` section because this isn't made to be enabled
-with `systemctl enable`, just executed with `systemctl start`, which the udev
-rule will do automatically. You'll want to modify the `ExecStart` line to point
-to your shell script.
-
-# Shell Script
-```
-#!/bin/sh
-# /home/ubuntu/autocopy.sh
-TIME=$(TZ=EST date +%F_%T) # used for folder name
-LABEL=DSi # the label of the SD cards filesystem
-MNT=/home/ubuntu/dsimnt # mount point of the sd card
-BACKUPDIR=/home/ubuntu/DSi # main directory all backups go to
-USBDEV=/sys/bus/usb/devices/1-1.5 # the sysfs entry for the usb device to use as a light
-
-# turn on the "led indicator" thats really a usb mouse torn apart
-echo 1 > ${USBDEV}/authorized
-mount "/dev/disk/by-label/${LABEL}" ${MNT}
-mkdir "${BACKUPDIR}/${TIME}"
-cp -r ${MNT}/* ${BACKUPDIR}/${TIME}/
-umount ${MNT}
-echo "done! you can remove the card."
-# turn that mouse back off
-echo 0 > ${USBDEV}/authorized
-```
-You'll want to change the `LABEL` variable to whatever the label of your SD card
-filesystem is.
-
-You will probably want to change the `TZ=EST` inside the `TIME` variable unless 
-you happen to live on the eastern coast of the United States.
-
-The mount point in the `MNT` variable is where the SD card should mount, which
-can be anywhere.
-
-The `BACKUPDIR` variable should be on a separate drive unless you have a 
-decently sized microSD inside your Pi that you don't mind filling up.
-
-The `USBDEV` variable is the path to your USB "light" inside 
-`/sys/bus/usb/devices`. You can run `lsusb` to get the ID of the usb device,
-then `cat` the `idProduct` and `idVendor` files inside each usb device folder
-until you find the one that matches your usb device.
-
-## Final Product
-
-What you'll have is something you can plug your SD card into and have a backup
-taken automagically. The light turns on when it's copying files, and turns off
-and unmounts the card when its done.
-You can see [a video of it working](/assets/sdcardpithing.mp4) here. Excuse the
-mess :) To access these backups, just go to the backup directory.
