How to use

1. Clone this repo to your Raspberry Pi, e.g. with https://github.com/Tronde/raspberrypi-dd-backup.git.
2. cd raspberrypi-dd-backup # Change into project directory.
3. Copy CONFIG.sample to config, e.g. cp CONFIG.sample config. This way you won't overwrite your confi when you pull the upstream repo with a changed CONFIG.sample.
4. Edit config and specify SRC, DEST and wether or not you like to use compression. SRC is the name of the sdcard you want to backup, i.e. /dev/mmcblk0. You could find the name of your sdcard with lsblk or in your /etc/fstab. DEST is the path to where the backup should be written, i.e. /mnt/backup-target/image-file-name.img. In case you would like to keep multiple backups you could automatically attach the current date to the filename, e.g. /mnt/backup-target/raspi-sht21-$(date +%Y-%m-%d).img.
5. Optional: Setup cronjob to run raspberrypi-dd-backup.sh as root to schedule your backup job
