How To Take Hot Backup Of Raspberry Pi Without Removing The SD Card

Since we are supposed to do a lot of tweaking and tinkering with our Raspberry Pi installations, it is always a good idea to backup the working SD card image before venturing for any experimentation. One way to do this is to take the whole SD card out and use another Windows/Mac computer to backup and restore the full sd-card image as demonstrated earlier. To save you with this much hassle, here we are with another method to perform automated "hot backups" from a Raspberry Pi itself to an external USB disk drive or remote storage. Simply use the provided Shell script and enjoy fast, efficient and automated RPi backups.

Automated Raspberry Pi Backup Script

Just save the below shared Shell script (use right-click and "save as" this link) on your RPi and execute using sudo ./ This script disables the "tar" compression command from the original version as it takes "too much" time on our little Pi, to get back that functionality simply uncomment the two relevant lines.

Any chance you could show how to restore a backup made with this?

When I needed a restore it was harder then I thought due to lack of another linux computer, you will need to google for how to restore dd images. This also came very handy for me - for getting data back from image on a windows computer.

It seems to work fine.
Thank you so much for the script. It's exactly what I was looking for.

I know this is old now, but thank you SO MUCH! It has saved me lots of time in trying to do one myself :D One thing for anyone running this; Line 67 needs changing as we are no longer compressing the file:

rm -f $DIR/backup_*.tar.gz
rm -f $DIR/backup_*.img

Thank you very much for this script.
On my Raspberry Pi 3 the backup process completes succesfully.

This was just awesome, run and working like a charm on my Raspi 2. Thanks a lot for sharing!!
