Backup samba shares from raspbery pi box

Here is a simple script that backups samba shares from linux box.

1. Create backup script

   Create backup script and save it as /root/backup.sh

   #!/bin/bash
   
   # Gets the latest date and time
   DATE=`date '+%Y%m%dT%H%M%S'`
   
   # The root directory that contains the backups
   BACKUP_ROOT=/home/thexman/backup
   
   # Current backup directory
   BACKUP_DIR=$BACKUP_ROOT/$DATE
   
   # Current zip file
   BACKUP_ZIP=$BACKUP_ROOT/$DATE.zip
   
   echo "Creating backup directory $BACKUP_DIR"
   
   #create backup directory if it doesn't exists
   mkdir -p "$BACKUP_DIR"
   
   echo "Mounting samba share..."
   
   # Mount windows shares to /mnt
   mount -t cifs //192.168.99.93/c$ -o "username=administrator,password=1234" /mnt
   
   echo "Creating backup copies..."
   
   # Copy files from windows machine to backup directory
   rsync -rzvh "/mnt/temp" "$BACKUP_DIR"
   #rsync "/mnt/source_directory1" $BACKUP_DIR
   #rsync "/mnt/source_directory2" $BACKUP_DIR
   #rsync "/mnt/source_directory2" $BACKUP_DIR
   
   echo "Creating zip archive $BACKUP_ZIP"
   
   # Archive the backup directory to zip file
   cd "$BACKUP_ROOT" && zip -r "$BACKUP_ZIP" "$DATE"
   
   echo "Removing backup directory $BACKUP_DIR"
   
   # Remove the backup directory
   rm -rf "$BACKUP_DIR"
   
   echo "Umounting samba shares..."
   
   # Release windows shares
   umount /mnt
   

2. Schedule backup script

   Execute following command "sudo crontab -e" and append following at the end of the file (it will execute the script at 21:15 every day)

   # m h  dom mon dow   command
   #15 21 * * * /root/backup.sh
