Cannot update backups of LimeSurvey

In my note and in the Puppet configuration I see:

/usr/sbin/backupninja --now --debug --run /etc/backup.d/10.mysql

But when executing this, either as sajolida or as www-data I get the following error message:

/usr/sbin/backupninja --now --debug --run /etc/backup.d/10.mysql

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
