Backup Utility

Was wondering if there is a utility similar to the Khadas Krescue boot utility that allows one to backup/install emcc images??

I found it very useful to backup my Khadas images as well as installing different os.   The description is as follows:

 

'Krescue is an extremely small (21mb) operating system that you can boot directly from a micro-SD card or your EMMC. It is a “Swiss Army knife”, and you can use it to perform a variety of low-level SBC maintenance tasks. Most notable of which are backing-up your EMMC by dumping a raw-compressed .img.gz, and rapidly installing a new OS via flashing a .img.gz back into the EMMC. Krescue can download and install OS images directly from the web via wired Ethernet.'

 

I've finally got my Heliios64 about 2 weeks ago and have it setup to the point I believe its ready for primetime but would like to ensure I have an easy way to backup/restore my emcc image.  Any thoughts?

Armbian is a community driven open source project. Do you like to contribute your code?

I am using the following modified version of an Armbian Script to rsync emmc to sd (replace UUIDs to match yours):

 

# cat backuptosd.sh
#!/bin/bash

# Check if user is root
if [ $(id -u) != "0" ]; then
    echo "Error: You must be root to run this script."
    exit 1
fi

cat > install-exclude <<EOF
/dev/*
/proc/*
/sys/*
/media/data1/*
/media/data2/*
/media/data3/*
/media/data4/*
/media/data5/*
/mnt/sd/*
/mnt/ssd/*
/mnt/usb/*
/mnt/hd/*
/run/*
# /tmp/*
# /root/*
EOF

exec 2>/dev/null
umount /mnt/sd
exec 2>&1

mount /dev/mmcblk0p1 /mnt/sd
rsync -avxSE --delete --exclude-from="install-exclude"  /  /mnt/sd

# change fstab
sed -e 's/UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx3c/UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx2d/g' -i /mnt/sd/etc/fstab
sed -e 's/UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx3c/UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx2d/g' -i /mnt/sd/boot/armbianEnv.txt
umount /mnt/sd
rm install-exclude
