Methods and systems for creating full backups

摘要

A computer-implemented method may include creating a first full backup of a set of data units at a first time. The computer-implemented method may also include identifying one or more data units in the set of data units that have been modified since the first time. The computer-implemented method may further include creating a second full backup of the set of data units by providing copies of the one or more data units that have been modified since the first time and storing references to copies of one or more data units in the set of data units that have not been modified since the first time. The references may be configured such that the second full backup is a standalone backup that is independent of any other backups.
