VSS writers, also known as Volume Shadow Copy Service writers, are software applications that create and manage shadow copies of data volumes. Shadow copies are point-in-time copies of a volume that can be used for backup and recovery purposes. VSS writers are an important part of a comprehensive data protection strategy, as they allow businesses to recover data in the event of a system failure or data loss.
VSS writers work by intercepting write requests to a volume and creating a copy of the data before it is written to the volume. This ensures that a consistent copy of the data is always available, even if the original data is lost or corrupted. VSS writers can be used to create shadow copies of both local and remote volumes, and they can be configured to create shadow copies on a scheduled basis or on-demand.
