A failover cluster is a group of independent computers that work together to increase the availability of applications and services. The clustered servers (called nodes) are connected by physical cables and by software. If one of the cluster nodes fails, another node begins to provide service (a process known as failover). Users experience a minimum of disruptions in service.
EVnearSync has supported installation of EVnearSync Agents on Windows cluster environment since version 4.0.
There are 2 configuration steps required in order to install EVnearSync Agent on Windows cluster environment:
1) When you are installing EVnearSync Agent you will be prompted for the clustering service name. Specify the clustering service name and follow the wizard. You need to ensure that the EVnearSync Agent is installed on all clustered nodes.

If everything goes well the EVnearSync Agent will be registered using the clustering service name in EVnearSync Administration Interface (Manage > Services > EVnearSync); i.e. the EVnearSync Agent Service is not registered using a node name:

That’s the configuration linked to EVnearSync.
2) The last part of the configuration needs to be done in the Failover Cluster Manager.
The goal is adding of a generic service resource for EVnearSync Agent Service with dependency on Enterprise Vault Task Controller Service.
This knowledge base article describes how to add EVnearSync Agent Service as a generic service resource on Windows Server 2012 R2. This process might be slightly different on the other versions of Window servers.
Please follow these steps (valid for Windows Server 2012 R2):
1. Launch Failover Cluster Manager.
2. Right click on Roles of your cluster and choose Configure Role… from the context menu.
3. High Availability Wizard appears. After reading the information presented on Before You Begin page, click Next.
4. On Select Role page, select Generic Service and click Next.
5. Select Service page appears. This page lists all the services that are running on the clustered nodes. Select “EVnearSync Agent Service” and click Next.
6. On Client Access Point page, you will be providing input for the network name and IP addresses that clients will be using when accessing the highly available generic service. Click Next.
7. On Select Storage page, you have an option to choose a disk for the generic service. EVnearSync Agent Service is not going to use any disk, so you don’t need to make any selection. Click Next.
8. On Replicate Registry Settings page, you can add the registry keys that the service will be using/updating. These are the keys that the service requires for it to function properly. EVnearSync Agent Service does not require any specific registry key to be functional. Click Next.
9. On Confirmation page, you can review your configuration. Click Next.
10. The Wizard should successfully create the generic service resource and bring the resource online. A Summary page appears. On Summary page, you can click on View Report… button. This will show you detailed report of what actions were taken to create the generic service resource. Click Finish.
11. New role should be visible in the Failover Cluster Manager:

12. Right-click on the role properties. On the Dependencies tab you can configure dependency on Enterprise Vault Task Controller Service
