Thanks @thib3113 for opening the issue.
Let me have a look at it.

I will contact you soon.

Hi @aessing , In fact, I just saw my first link is too specific ( link to a commit, and not the branch ) .

I've done another commit just after commeting, because I forgot to take some changes from local .

About the ${CRON_SCHEDULE} , in fact I add it on line where I echo the cron to cron file .

So, with that, I totally separe vars, and code . And we can say "stop to edit after line XXX" .

But, it's as you prefer .

I'm preparing the PR

Hi @thib3113,

Thanks for your contribution.
Please open a PR for your change. I will merge them into the repo.

I found a few small things in your code I would like to ask you to change before merging:

• You forgot the CRON_SCHEDULE in line 50. It should look like:

CRON_CMD="${CRON_SCHEDULE} ${CRON_CMD} ${BACKUP_IMG}"

• Could you please remove the comment hash on line 54 and enable writing to the cronfile. So remove line 54 and line 53 should look like:

 echo "${CRON_CMD}" > ${CRON_FILE}

Also could you please remove the comment hash from line 35, as the standard schould be backup up both services. Perhaps you can add a comment, how to disable backup for Protect.

Thanks
Andre
