Mounting net drives, creating backups is always a recurring topic I treat different in my different machines.

I will try to explain the approach I took with my Homeassistant Files which are installed in a Raspberry Pi.

I will create a bash script which will be executed with a cronjob every week to backup the important directories of the raspberry pi with rsync

Let’s start!

First of all I created a file with the credentials of my network drive on /root/

sudo nano /root/.networkdrivecredentials

user=myuser
password=mypassword

and I make the file only accessible for root

sudo chmod 700 /root/.networkdrivecredentials

After that I check that the mounting of the drive with the credentials work

sudo mkdir /media/NETWORK-DRIVE

sudo mount.cifs //IP-NETWORK-DRIVE/MyFolder /media/NETWORK-DRIVE -o credentials=/root/.networkdrivecredentials

It worked! Now the Script works more or less like this

  • Check if the Network drive is mounted, if not mount it
  • Rsync the needed directories
  • Unmount the network drive
#!/bin/bash

if [ -d "/media/NETWORK-DRIVE/MyFolder" ]; then
    # Control will enter here if $DIRECTORY exists.
    echo "Drive mounted!"
else
    echo "Not Mounted"
    mount.cifs //IP-NETWORK-DRIVE/MyFolder /media/NETWORK-DRIVE -o credentials=/root/.networkdrivecredentials
fi

rsync -avzh /home/MyFolder/ /media/NETWORK-DRIVE/
sudo umount /media/NETWORK-DRIVE
