What is sqlwriter.exe?

Part of Microsoft SQL Server by Microsoft

What is it?

The SQL Writer Service provides added functionality for backup and restore of SQL Server through the Volume Shadow Copy Service framework.
Description of sqlwriter.exe from Microsoft
The SQL Writer Service is installed automatically. It must be running when the Volume Shadow Copy Service (VSS) application requests a backup or restore. To configure the service, use the Microsoft Windows Services applet. The SQL Writer Service installs on all operating systems. When running, Database Engine locks and has exclusive access to the data files. When the SQL Writer Service is not running, backup programs running in Windows do not have access to the data files, and backups must be performed using SQL Server backup.
