Documentation

Overview

Package vss backs Windows backups with Volume Shadow Copies: every volume a job's paths live on is snapshotted, the shadow copy is exposed through a directory symlink under the agent's data directory, and the job's paths are remapped onto it so open and locked files are read from a consistent point in time. On other platforms nothing is snapshotted.
