If the "Connections" and "Credentials" features are being used the backups for VisualCron can pose a security risk, in particular in larger organizations.
The backups are not encrypted or secured, and are relatively difficult to shield from VisualCron operators as visualcron offers all sorts of flexible ways of moving files or accessing the server.
If you import a backup into a new instance the credentials stored in the backup can be used from another instance quite easily. These can include server and database credentials.

As backups are already zipped please introduce a feature which allows you to uses the .zip encryption and password protect and encrypt the backups so these can be protected in a better way.
