LSDF Online Storage: Snapshots

Snapshots are used to create a point-in-time copy of a file system or file sets. Snapshots can be used to quickly restore files or folders that were unintentionally deleted. Snapshots also provide a form of file versioning and the ability to revert to a previous version of a file, depending on the time interval between snapshots.
