healthcheck ping at backup completion

[nmatton]

Hello,

I've just setup the backup process but I'm looking to use a monitor service to check if backup is going OK every day.
I was that I get a "success" notification once conected on the server instance, but I often go to the UI as I'm mainly using NC for the file management directly on my devices.

I'm used to healtcheck but all other can fit my needs

Did I missed something or it is not (yet?) possible ?

Thanks !

Hi, such a healthcheck is unfortunately not implemented currently. You would need to check fhe exit code of the borgbackup container after the container was stoped which is what aio uses internally.

Thanks for the idea!

I created a script for this purpose with a cron entry.

Here it is for reference, in case others have the same interest.

#!/bin/bash

# variables
LOG_LINES=20
LOG_FILE="/var/log/nextcloud-backup-$(date +%F).log"
CONTAINER_NAME="nextcloud-aio-borgbackup"
HEALTHCHECKS_URL="https://hc-ping.com/<healthcheck-id>" #adding here the HC id

# get the exit code of the container
get_backup_exit_code() {
    sudo docker inspect $CONTAINER_NAME --format='{{.State.ExitCode}}' 2>/dev/null
}

# get the status of the container
get_backup_status() {
    sudo docker inspect $CONTAINER_NAME --format='{{.State.Status}}' 2>/dev/null
}

# Check if the backup container exists
if ! sudo docker ps -a --format '{{.Names}}' | grep -q "^$CONTAINER_NAME$"; then
    echo "[$(date)] Backup container $CONTAINER_NAME does not exist." | tee -a $LOG_FILE
    CONTAINER_LOGS="Backup container $CONTAINER_NAME does not exist."
    # Send logs to Healthchecks.io
    curl -fsS --retry 3 -X POST --data-binary "$CONTAINER_LOGS" "${HEALTHCHECKS_URL}/fail" > /dev/null
    exit 1
fi

# Wait until the backup container has stopped (in case it's still running)
while [ "$(get_backup_status)" == "running" ]; do
    echo "Backup is still running. Waiting..."
    sleep 600  # Wait for 10 minute before checking again
done

EXIT_CODE=$(get_backup_exit_code)

CONTAINER_LOGS=$(sudo docker logs --tail $LOG_LINES $CONTAINER_NAME 2>&1)

# Check the exit code and send notifications
if [ "$EXIT_CODE" -eq 0 ]; then
    echo "[$(date)] Backup was successful." | tee -a $LOG_FILE
    # Send logs to Healthchecks.io
    curl -fsS --retry 3 -X POST --data-binary "$CONTAINER_LOGS" "${HEALTHCHECKS_URL}" > /dev/null
else
    echo "[$(date)] Backup failed with exit code $EXIT_CODE." | tee -a $LOG_FILE
    # Append the full logs to the log file
    sudo docker logs $CONTAINER_NAME >> $LOG_FILE
    # Send logs to Healthchecks.io
    curl -fsS --retry 3 -X POST --data-binary "$CONTAINER_LOGS" "${HEALTHCHECKS_URL}/fail" > /dev/null
fi
