A VSS writer is a software program that creates and manages shadow copies of data volumes. Shadow copies are point-in-time copies of data that can be used to recover data in the event of data loss. VSS writers are an important part of a data protection strategy because they provide a way to recover data quickly and easily.
VSS writers are typically used in conjunction with a backup application. The backup application creates a schedule for creating shadow copies and the VSS writer creates the shadow copies according to the schedule. Shadow copies can be created for any type of data volume, including system volumes, boot volumes, and data volumes.
