Backing Up Magic Mirror

AAPS

I was wondering how to backup my SD card. I already have Win32DiskImager installed on my computer, but I wanted to know how exactly to set up a backup in case something happens to my raspberry pi.

You just put your SD card in and instead of writing to the card you do a read… name your image file and store it somewhere safe in case you need it :)

I still do not understand. I don’t know the name of my img file.

@AAPS

sudo nano /home/pi/Backup.sh

#!/bin/bash

# VARIABLEN - HIER EDITIEREN
BACKUP_PFAD="/yourBACKUPpath"
BACKUP_ANZAHL="5"
BACKUP_NAME="raspicam3-HN_BMGT"
DIENSTE_START_STOP="service mysql"
# ENDE VARIABLEN

# Stopp any services before backup
${DIENSTE_START_STOP} stop

# Create backup with dd in your desired path
dd if=/dev/mmcblk0 of=${BACKUP_PFAD}/${BACKUP_NAME}-$(date +%Y%m%d-%H%M%S).img bs=1MB

# Star services after backup
${DIENSTE_START_STOP} start

# Delete old backup after X backups
pushd ${BACKUP_PFAD}; ls -tr ${BACKUP_PFAD}/${BACKUP_NAME}* | head -n -${BACKUP_ANZAHL} | xargs rm; popd

Make executable and move the script to /usr/bin/

sudo chmod 755 /home/pi/Backup.sh
sudo mv /home/pi/Backup.sh /usr/local/bin/Backup.sh

crontab -e

00 01 * * * /usr/local/bin/Backup.sh

Every day at 01:00 in the night a backup with crontab.

Restore your Backup to your SD-Karte under Windows with Win32 Disk imager or with Linux with following command.

dd if=/path/backup.img of=/dev/sda bs=1MB

create manual a backup with your pi

sudo dd if=/dev/mmcblk0 of=/yourBACKUPpath/Rpi_32gb_backup.img bs=2M
