Abstract

A backup method that uses snapshot delta views to create backups of a data collection is provided. The method comprises taking a first snapshot of the data collection, in response to determining that a previous snapshot used to create a backup does not exist; creating a backup of the data collection using the first snapshot, in response to determining that the previous snapshot does not exist; recording that the first snapshot was used as a source for the creation of a backup; and taking a second snapshot of the data collection, in response to determining that the previous snapshot that was used as a source for a backup does exist.
