This issue is identified when there are multiple instances installed in the same network drive machine/server and in cluster.

As the backup_export was scheduled in cron and each cronjob was pointing to a single instance of the cluster which was failing to read the encryption password property.

To resolve this issue, please make sure each scheduled cronjob is pointing to it own installation directory.
