EVnearSync Administration Guide

EVnearSync has an intuitive web interface for configuration of Enterprise Vault data replication. Initially you’ll configure replication for data at the Vault Store level. The web interface can be accessed via the console session where the EVnearSync Core/Web components were installed using this URL: http://localhost/EVnearSync

In addition, you can access the web interface remotely from a workstation using this URL: http://servername.domainname/EVnearSync

Note: The first time you open the site, there can be a delay before the screen displays. This is because of the way that ASP.Net works. It is normal.

System Status

System Status page is where the overall system status can be found. You can find the page by going to Monitor > System Status. The page consists of three panels of information: Replication Gap, Service Status and Failover Status, and Replication Charts.

Replication Gap

Each Vault Store is represented by a rectangular colored block. Each color is defined below.

In addition, there are two data figures shown in each rectangle:

  • Number at top right: Replication gap, i.e. how many savesets are left to replicate.
  • Number at bottom left: Total size of the Vault Store

Service Status and Failover Status

This area shows information about whether EVnearSync is running correctly, and whether a storage failover has happened.

Replication Charts

This area at the bottom of the main window shows the number of items and the volume of replication. It refreshes every 10 minutes. The amount of space available on the targets is also indicated in a third chart.

Consistency Checks

The Consistency Checks page in the Admin Console shows the current progress of any running consistency checks. Open the page by going to Monitor > Consistency Checks.

Each Vault Store is represented by a rectangular colored block. Colors are defined below.

Services

The Services page in the Admin Console shows the current status of services in the environment. Access the page by going to Monitor > Services. It shows both Enterprise Vault services and EVnearSync services.

Alerts

The Alerts page in the Admin Console shows any active alerts, and it allows for the alerts to be acknowledged. Access the page by going to Monitor > Alerts.

Vault Store Replication

On the Vault Store Replication page you can review the replication that has been configured in the environment, and you can make any necessary changes. You can find this page by going to Manage > Vault Store.

Modify Vault Store Partition

If needed, individual Vault Store Partitions can be modified after the wizard runs. This is useful if the destination needs to be changed on any Vault Store Partitions.

Disable/Enable Replication

If needed, individual Vault Store Replication can be disabled or enabled.

Full Consistency Check

A full consistency check will verify that all data in the Vault Store has been replicated and is consistent between source and destination.

To perform this task, expand the Vault Store you want to modify, select the Vault Store, and click Modify > Full Consistency Check.

This is very resource intensive. There are daily consistency checks that run on a specific schedule. Before running the full consistency check, you’re asked to confirm the action.

Index Replication

The initial configuration should be done via the Index Replication Enablement Wizard. This is accessed by going to Manage > Index.

Index Replication Enablement Wizard

To configure replication for the first time, select the Add Index Wizard button. Then, follow these steps:

  1. Select the Source Computer. To do this, on the first page of the wizard you’ll see a list of servers in the environment that have an indexing service. From the drop-down list, select the one you want to configure for replication, and then click Next.
  2. Set the destination path. This is the path to the remote location where you want the replicated data to be sent.
  3. Select EVnearSync service that is being used for the replication. This will normally be the Agent Service located on the Enterprise Vault server hosting the Index Service.
  4. Specify any pre- and post-replication commands you want to perform with any additional parameters. Pre- and post-replication commands can be specified and uploaded on the Settings > Other > Pre/Post Scripts page. This is covered below.
  5. Specify when you want the replication tasks to be performed, and then click Finish.

SQL Database Replication

EVnearSync can replicate a SQL database by replicating a SQL ‘dump’ file to a remote location.

The initial configuration happens via the Add SQL Replication Wizard. This is accessed by going to Manage > SQL Database.

Click the Add SQL Replication button to launch the wizard. Then, follow these steps:

  1. Select the source and destination paths for replication. The source and remote locations specified are validated to ensure that they exist. The source and remote location must be specified as UNC paths.
  2. Select the EVnearSync service that is being used for the replication.
  3. Specify any pre- and post-replication commands you want to be performed with any additional parameters. Pre- and post-commands can be specified and uploaded by going to Settings > Other > Pre/Post Scripts. This is covered later in this document. Pre- and post-backup scripts are used as described in this Symantec article.
  4. Specify when you want the replication tasks to be performed,  and then click Finish.

Custom Path Replication

EVnearSync can replicate any path on the Enterprise Vault server to a remote location. For example:

PST Holding folder (where .PST files are waiting for processing)
Vault Cache database build area.

The initial configuration happens via the Add Custom Replication Wizard, which you can access by going to Manage > Custom Path.

Click the Add Custom Replication button to launch the wizard. Then, follow these steps:

  1. Specify the source and destination paths for replication.
  2. Select the EVnearSync service that is being used for the replication.
  3. Specify any pre- and post-replication commands that you want to be performed with any additional parameters.
  4. Specify when you want the replication tasks to be performed, and then click Finish.

Failover and Failback

EVnearSync is constantly monitoring for failures in storage, indexing, and services. It will perform an automatic failover. However, occasionally you might need to perform a manual failover. This is possible with Vault Stores and Index locations, as described below.

Vault Store

To failover a Vault Store, go to Manage > Failover > Vault Store.

You’ll see a list of Vault Stores. If a Vault Store is expanded, it’s possible to see the current status and whether the primary storage is functioning or whether the Vault Store has been failed over.

Failover and Failback can also be performed from this screen.

When performing a Failback operation, a consistency check is automatically triggered.

Index

To failover an Index location, go to Manage > Failover > Index.

You’ll see a list of configured index replication elements and their current status.

Failover and Failback can also be performed from this screen.

Managing Services

Both the Enterprise Vault and EVnearSync services can be managed from the EVnearSync Core/Web interface.

  • EVnearSync: Manage EVnearSync services by going to Manage > EVnearSync.
  • Enterprise Vault: Manage Enterprise Vault services by going to Manage > Enterprise Vault.

Reports

EVnearSync has a number of reports that allow you to review operations performed by the product. To access the reports, click Reports and select the report you want to view. Reports are listed and described below.

  • Vault Stores: Shows the amount of data that has been replicated by EVnearSync.
