Abstract
Techniques for using sparse files during snapshots are provided. Snapshots are managed and maintained for a source volume via sparse files. Metadata defines the sparse files and operations of a file system are used to create, define, and manipulate the metadata. When a write operation is detected during a snapshot, sparse files are used to copy the write operation before the write operation is performed on the source volume; the sparse files server as the snapshot data.
