Dietpi-backup notification?

[pedrom34]

Hi!
Would it be possible to add a curl command in case of success/failure of dietpi-backup?
I had the surprise my destination was full like 2 months ago and dietpi-backup wasn't able to backup anything since.

I'd like to had a ntfy curl command to get a notification, but I don't really want to manually tweak dietpi-backup script... (And even if I wanted to, I wouldn't know where to start 😅 )

There is this .dietpi-backup_stats file inside the target directory which shows a "Backup completed" in the last line in case of success. So that could be checked for.

But I would not implement an own notification system for dietpi-backup only. Instead, a general notification system for certain configurable events or failing checks would be great: #2663

Sending E-Mails should be just one option, a banner notice, webhook, and custom command to call would be good additions.

That's great. I'll workaround that file, thanks!
I already made scripts for dietpi upgrades, for package updates availability and for reboot events. I think I'll find a way to do this. Thanks a lot 👍

here's what I wrote.

I need to test it when it fails. And maybe I'll attach the logfile, but for the moment it works:

#!/bin/bash
LOG_FILE="/location/of/the/backup/dietpi-backup/.dietpi-backup_stats"
PATTERN="Backup completed"
LAST_LINE=$(tail -n 1 "$LOG_FILE")

if echo "$LAST_LINE" | grep -q "$PATTERN"; then
    curl \
      -u :tk_xxx \
      -H "Title: Dietpi-backup completed successfully" \
      -H "Tags: minidisc, heavy_check_mark" \
      -d "The last dietpi-backup completed successfully" \
      https://ntfy.sh/lalalala
else
    curl \
      -u :tk_xxx \
      -H "Title: Dietpi-backup failed" \
      -H "Tags: minidisc, rotating_light" \
      -d "The last dietpi-backup failed! Go check log!" \
      https://ntfy.sh/lalalala
fi

Neat! Pattern check can be done with pure shell:

if [[ $LAST_LINE == *"$PATTERN"* ]]; then

thanks!

Here's a V2 with log sending:

#!/bin/bash

LOG_FILE="/location/of/the/backup/dietpi-backup/.dietpi-backup_stats"
PATTERN="Backup completed"
LAST_LINE=$(tail -n 1 "$LOG_FILE")

if [[ $LAST_LINE == *"$PATTERN"* ]]; then
    curl \
      -u :tk_xxx  \
      -H "Title: Dietpi-backup completed successfully" \
      -H "Tags: heavy_check_mark" \
      -d "Latest dietpi-backup completed successfully" \
      https://ntfy.sh/lalalala
else
    curl \
      -u :tk_xxx  \
      -H "Title: Dietpi-backup failed ! See attached log !" \
      -H "Tags: rotating_light" \
      --data-binary @/location/of/the/backup/dietpi-backup/dietpi-backup.log \
      -H "Filename: dietpi-backup.log" \
      https://ntfy.sh/lalalala
fi

And the result:
