This script does an image backup of the Pi SD card using dd. It is not the most efficient method, but it creates a complete backup and it's easy to restore in case of complete card failure.
- Clone this repo into the folder where you keep your housekeeping scripts.
- Modify the MOUNTPOINT and SUBDIR variables to point to your destination
- Modify STARTSTOPSERVICE variables to 1 if you want your serives stopped/started
- Update services stop and start sections to reflect your installated services
- Optional: Modify GZIP variable if you want your backups zipped
- Make executable.
chmod +x backup.sh - Update crontab to run each it each night.
Example
Update /etc/crontab to run backup.sh as root every night at 3am
01 3 * * * root /home/pi/scripts/backup.sh
The backup took a little more than an hour on my first run (SD card to USB HDD).
This script started from http://raspberrypi.stackexchange.com/questions/5427/can-a-raspberry-pi-be-used-to-create-a-backup-of-itself which in turn started from http://www.raspberrypi.org/phpBB3/viewtopic.php?p=136912

Merged in later comments from the original thread (the pv exists check) and added the backup.log
