Performing a failover

Performing a failover

If the production site becomes unavailable, or you need to move the workload to the disaster recovery (DR) site, you can perform a failover operation from the vRanger UI.

A failover operation consists of the following actions:

•	Turning on the production VM.

•	[Optional] Performing a final synchronization between sites. This action ensures that no data is lost during a failover. If you do not want to synchronize changes — in the event of a virus, perhaps — or cannot (if a hardware failure occurred), data changed since the last replication pass is lost.

•	Turn on the DR VM.

•	Reverse the replication job, with the DR VM now acting as the source.

 

NOTE: The first replication pass after failing over sends the entire image, not just the changed data.

To perform a failover:

1	In the My Jobs view, select a replication job.

2	Click the Failover icon.

3	When the confirmation message appears, click Yes.

4	When the Confirm Synchronization dialog box appears, select one of the following:

▪	Yes: This option shuts down the production VM and perform a final synchronization to the DR site. This option ensures that no data is lost, but also transfers any virus or corruption to the replica VM. View the replication progress in the Running Tasks section of the vRanger UI.

 

NOTE: If you are using differential replication, this option causes vRanger to perform a complete scan of the VM disks, as it does for every replication pass, but only changed data is sent to the replica VM.

▪	No: The production VM is turned off, but no changes are sent to the DR replica.

After the failover completes, the Destination of the original replication job is now the Source, and the original Source is now the Destination. In other words, the job is now set to replicate from the DR site to the Production site. This change is not reflected in the vRanger UI. Jobs that have been failed over are indicated by a failover icon and tool-tip message.

5	If the production site is unavailable, or you do not want to replicate changes, disable the replication job.

Performing failback

Performing failback

When the production server has been returned to proper operation, you usually need to failback the replicated VM to the production site. A failback is simply a failover back to the production site.

A failback operation involves the following events:

•	Turning off the disaster recovery (DR) VM.

•	[Optional] Performing a final synchronization between sites. This action ensures that any data changed on the DR VM is replicated back to the production site. If you do not synchronize changes, data changed since the last replication pass is lost.

•	Turn on the production VM.

•	Reverse the replication job — return to the jobs original configuration — with the DR VM now acting as the target.

•	If the job is enabled, replication continues, sending changes from the source production VM to the DR target.

 

NOTE: The first replication pass after failing back re-scans the entire image to identify changed blocks. Only changed data is sent.

To perform a failback:

1	In the My Jobs view, select a replication job.

2	Click the Failback icon.

3	When the confirmation message appears, click Yes.

4	When the Confirm Synchronization dialog box appear, select one of the following:

▪	Yes: This option ensures that any data changed on the DR VM is replicated back to the production site. If you do not want to synchronize, data changed since the last replication pass is lost. View the replication progress in the Running Tasks section of the vRanger UI.

▪	No: The DR VM turned off, but no changes are sent to the Production site.

After the failback completes, the direction of replication reverses again, this time returning to the original configuration. The Failover icon is no longer shown.

Reports

About vRanger reports

The My Reports view is a gateway to creating, editing, and distributing custom reports. There are several report types:

•	Backup Job Summary Report

•	Backup Task Report

•	Replicate Job Summary Report

•	Replicate Task Report

•	Restore Job Summary Report

•	Restore Task Report

As you create reports, the documents nest under the node of the relevant report type. When you create a backup job, you can configure a report to display in the body of an email. The report indicates which jobs were run, which succeeded, and which failed. You can also schedule a report to run, save it as a PDF, and send it as an email attachment.

Report information is organized by VM and includes when backups, replicates and restores were run, who ran them, and the status of each. You can create a report for results from one or multiple VMs. Reports can contain customized metrics — for example, date range (day, month), status (successful, failed, stopped). You can run reports when you create them or you can schedule them to be generated later.

For information on the layout of the My Reports view, see My Reports view.

Generating a report using the Report Wizard

Generating a report using the Report Wizard

Through the Report Wizard, you can generate reports that are filtered by date/time and status. For example, you can generate a report that includes only backup or restore tasks or jobs that failed over the last 10 days.

Complete the steps in the following procedure to schedule a report using the Report Wizard.

To use the Report Wizard:

1	In the main vRanger UI, click the My Reports view.

2	Start the Report Wizard by doing one of the following:

▪	Right-click one of the nodes, and click Add.

▪	Select one of the nodes, and then click the Add icon on the View toolbar.

3	On the Report Filter page, enter the information as described in the following table.

 

Option	Description
Date Range	Narrow report data using these fields: • Over the last: Enter the number in the first field and select Days or Months from the drop-down list — the default is 30 days. • Between: Click this option button to enable the two drop-down date lists. Click each to display a calendar from which you can select a date range.
Machine/Source Repository	• Machine: Select a machine type — to restrict report data. • Source: From this drop-down list, you can select All or any individual source. All licensed, available sources are listed here. • Repository: This drop-down list allows you to filter the report results by repository.
Duration	In this section, you can enter a number in the Greater than or equal to __ minutes field. The value you enter restricts the report to include only jobs that occurred within that time limit —  the default is 0.
Job Status	The check boxes available in this section refer to the status of any job that you might include in reports. Available values are: Completed, Failed, Aborted, and Cancelled. NOTE: Because Jobs cannot fail (Tasks within Jobs can), searching for Job Status - Failed yields no results. To generate a list of unsuccessful activities, search for Task Status - Failed.

4	On the Column Selection page, customize your report by doing the following:

▪	Under Selected Columns, select any column you do not want to include in the report, and then click Clear Column to move it to the Available Columns field and remove it from the report. Columns include the following:
