Performing VSS backups in SQL Server®

Microsoft provides a SQL Server VSS Writer that permits backup solutions such as Plug‑in for SQL Server to copy SQL Server data while SQL Server is running. VSS-based backups do not negatively affect SQL Server’s performance or stability.
IMPORTANT: Before initiating VSS backups, verify that the SQL Server VSS Writer service is running on the SQL Server. The SQL Server VSS Writer is automatically installed with SQL Server. However, the service is not enabled to start automatically. For VSS backups, start this service from the Windows® Services panel — Start > Control Panel > Administrative Tools > Services. Dell recommends that you set the Startup Type for this service to Automatic.

You can define a VSS backup job regardless of the state of this service. However, the job fails if it is run while the SQL Server VSS Writer service is not running. The log for the failed backup job contains a message stating “Please ensure the SQL Server Writer service is started.”

Selecting data for a VSS backup

TIP: To use an existing set, click Create Backup Job, and select the set from the Selections list.

In the Navigation pane, click Create Backup Job.
You can also start the wizard from the Guided Configuration link. In the Navigation pane, click Guided Configuration. On the NetVault Configuration Wizard page, click Create backup jobs.

In Job Name, specify a name for the job.

In the list of plug-ins, open Plug‑in for SQL Server, and then open the All Instances node to view the individual instances.

The name can contain alphanumeric and non-alphanumeric characters, but it cannot contain non-Latin characters. On Linux®, the names can have a maximum of 200 characters. On Windows, there is no length restriction. However, a maximum of 40 characters is recommended on all platforms.
