Hi,
I’d like to set my Nextcloud into maintenance mode and dump the database before running the backup.
I tried 2 commands in the run-script-before line:
sudo -u www-data php /var/www/html/cloud/occ maintenance:mode --on && echo myPassword | sudo -u root mysqldump --single-transaction -h localhost -u nextcloud -pmyPassword nc > /media/2TBint/backup/nc/nextcloud-sqlbkp_'date +"%Y%m%d"'.sql
It does not work and I get no message in Duplicati log.
Alternatively I packed the commands in a shell script to run before backup. But this exits with code 255.
I can say that the script works. When I start it as cronjob all is fine.
What can I do to get it working just before the backup?
