CuboxBackup.sh

Script to backup a Cubox (imx6) SDCARD to an imagefile

Author / Origin:

Dolorosus

Usage

CuboxBackup.sh

Usage:

• CuboxBackup.sh COMMAND OPTION sdimage

E.g.:

• CuboxBackup.sh start [-cslzdf] [-L logfile] sdimage
• CuboxBackup.sh mount [-c] sdimage [mountdir]
• CuboxBackup.sh umount sdimage [mountdir]
• CuboxBackup.sh showdf sdimage
• CuboxBackup.sh gzip [-df] sdimage

Commands:

• start - starts complete backup of cubox's SD Card to 'sdimage'
• mount - mounts the 'sdimage' to 'mountdir' (default: /mnt/'sdimage'/)
• umount - unmounts the 'sdimage' from 'mountdir'
• showdf - shows a df of the 'sdimage'
• 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'
• -s define the size of the image file

Examples:

Start backup to backup.img, creating it if it does not exist:

CuboxBackup.sh start -c /path/to/backup.img

Start backup to backup.img, creating it if it does not exist, limiting the size to 8000Mb. Remember you are responsible defineing the image size large enough to hold all files to backup! There is no size check.

CuboxBackup.sh start -s 8000 -c /path/to/backup.img

Refresh (incremental backup) of backup.img. You can only refresh a noncompressed image.

CuboxBackup.sh start /path/to/backup.img

Mount the RPi's SD Image in /mnt/backup.img:

CuboxBackup.sh mount /path/to/backup.img /mnt/backup.img

Unmount the SD Image from default mountdir (/mnt/backup.img/):

CuboxBackup.sh umount /path/to/backup.img

Caveat:

This script takes a backup while the source partitions are mounted and in use. The resulting imagefile will be inconsistent!

To minimize inconsistencies, you should isolate the system to rescue before starting the backup. An example is provided at https://github.com/dolorosus/RaspiBackup/blob/master/WeeklyBackup.sh
