hi peeps.

Im early on my selfhosting journey and managed to setup some things as a test in docker. the main service im looking to run is ERPNext. after a while I got it up and running so now I want to back this up including all the customization I did in the app.

where to start with this? any intuitive guide?

    Out of curiosity, how are you doing the drive imaging?

    I wrote a script that is fired by a cron job once a month:

    sudo nano /usr/local/bin/backup_drive.sh

    spoiler
    # Directory to store backups
    
    BACKUP_DIR="/mnt/myhdd"
    
    # Drive to backup
    
    DRIVE="/dev/sdX"
    
    # Create a timestamp
    
    TIMESTAMP=$(date +"%Y%m%d")
    
    # Filename for the new image
    
    NEW_IMAGE="$BACKUP_DIR/my_drive_image_$TIMESTAMP.img"
    
    # Create the image
    
    sudo dd if=$DRIVE of=$NEW_IMAGE bs=4M status=progress
    
    # Keep the last 3 images
    
    ls -tp $BACKUP_DIR/my_drive_image_*.img | grep -v '/$' | tail -n +4 | xargs -I {} rm -- {}
    

    Make the script executable:

    sudo chmod +x /usr/local/bin/backup_drive.sh

    Create Cron:

    sudo crontab -e

    0 3 1 * * /usr/local/bin/backup_drive.sh

    Verify cron:

    sudo crontab -l

    I’m sure it could be written differently or that there is a better way to do the imaging, but that is the extent of my notes, and it works for me.

      Ah, good old dd

      When you have some spare time, take a look at partclone - clonezilla uses it because it only backs up used blocks, not free space, so more efficient.
