Through DeviceLink, Copia provides the ability to back up projects and files either on-demand or through scheduled operation. Using the Copia Web App, users of DeviceLink can configure their Projects and Devices for backup with a client-side app called the Copia Agent.
The example below demonstrates how an Organization might configure two Sites for DeviceLink:
As seen above, the Copia DeviceLink system consists of the following items:
Site
A Site is a logical grouping of user-defined Projects, Devices and Agents. A Site could be home to a factory, an area with a factory, a large region, etc.
Project
Projects are pointers to specific automation projects which are stored in the repositories within an Organization.
Device
Devices represent the actual hardware device(s) or location(s) that Projects are backed up from (i.e. PLC's, robot controller, etc). They often contain communication information, like an IP address.
Job
A Job is a scheduled operation that is used to perform a backup and comparison of your Project to the current instance in the Copia Server.
Agent
An Agent is a piece of software that will perform or request the actual backup of the Device directly. This is downloaded and installed on a PC in the customer network which has access to perform this operation.
The Copia Agent is a small client-side application that enables DeviceLink to back up the code running on customer devices to Copia's Git-Based Source Control product.
The Agent works through a specific set of operations:
The Agent will poll for Jobs from the Copia Web App via HTTPS at a polling interval of approximately 15 seconds.
If any Jobs are found, the Agent will attempt to communicate to the Device to perform the backup.
If the backup is successful, the program on the Device will be saved to disk in a temporary folder on the system. Prior to the next backup, the program will be deleted from local storage.
If the backup is successful, the Agent will upload the results to the Web App via HTTPS.
Agent Network & System Requirements can be found in the section of the Documentation.
