bkup_rpimage
Script to backup a Raspberry Pi disk image
Author / Origin:
Script developed on the RaspberryPi.org forums: The Raspberry Pi Backup Thread.
The script, as copied over to github.com, was primarily written by user: jinx.
I found this via a raspberrypi.stackexchange.com answer by user: ppumpkin.
The script was taken from here, a post from Mon Nov 10, 2014 7:05 am.
I copied the attached file on Wed Feb 01, 2017 to this git repository.
##Usage from Jinx and corrected the mistake of using rsync instead of start in the examples
bkup_rpimage.sh v1.0 by jinx
Usage:
bkup_rpimage.sh start [-clzdf] [-L logfile] [-i sdcard] sdimage bkup_rpimage.sh mount [-c] sdimage [mountdir] bkup_rpimage.sh umount sdimage [mountdir] bkup_rpimage.sh gzip [-df] sdimage
Commands:
start starts complete backup of RPi's SD Card to 'sdimage' mount mounts the 'sdimage' to 'mountdir' (default: /mnt/'sdimage'/) umount unmounts the 'sdimage' from 'mountdir' gzip compresses the 'sdimage' to 'sdimage'.gz
Options:
-c creates the SD Image if it does not exist -l writes rsync log to 'sdimage'-YYYYmmddHHMMSS.log -z compresses the SD Image (after backup) to 'sdimage'.gz -d deletes the SD Image after successful compression -f forces overwrite of 'sdimage'.gz if it exists -L logfile writes rsync log to 'logfile' -i sdcard specifies the SD Card location (default: /dev/mmcblk0)
Examples:
bkup_rpimage.sh start -c /path/to/rpi_backup.img starts backup to 'rpi_backup.img', creating it if it does not exist
bkup_rpimage.sh start /path/to/$(uname -n).img uses the RPi's hostname as the SD Image filename
bkup_rpimage.sh start -cz /path/to/$(uname -n)-$(date +%Y-%m-%d).img uses the RPi's hostname and today's date as the SD Image filename, creating it if it does not exist, and compressing it after backup
bkup_rpimage.sh mount /path/to/$(uname -n).img /mnt/rpi_image mounts the RPi's SD Image in /mnt/rpi_image
bkup_rpimage.sh umount /path/to/raspi-2014-11-10.img unmounts the SD Image from default mountdir (/mnt/raspi-2014-11-10.img/)
