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?

    Interesting.

    Yep, I agree there’s 2 types of backups:

    • data
    • OS image

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

      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.
