Automating Borg Backup with cron fails

Question

Background

I would like to use Borg Backup as a backup solution (backup on remote server). Borg offer sa very convenient sh script that they say you can just run as a cron job. While the script works flawlessly in the command line, but it's not working in cron.

I run Debian Bullseye.

How can I make it run on cron?

Here's a similar description of the problem, however, my repository is encrypted.

Root's Crontab

* * * * * /usr/local/bin/scriptborg.sh >> /home/t/dwnlds/log.txt 2>&1

scriptborg.sh

#!/bin/sh

# Setting this, so the repo does not need to be given on the commandline:
export BORG_REPO=ssh://[email protected]:2222/nas/mydirectory/backup/main

# See the section "Passphrase notes" for more infos.
export BORG_PASSPHRASE='mypassword'

# some helpers and error handling:
info() { printf "\n%s %s\n\n" "$( date )" "$*" >&2; }
trap 'echo $( date ) Backup interrupted >&2; exit 2' INT TERM

Notes

• I excluded borg compact from the script as this command is not working on Debian Bullseye

I'm very happy to get some help to resolve this issue!
