Abstract: Examples include splitting a non-leaf node of a directed acyclic graph (DAG) in response to determinations that a content-defined fingerprint of a data portion is a breakpoint value and that a target insertion point is between two leaf nodes having a common non-leaf node parent, and determination of whether the data portion was previously stored in a backup system based on the DAG.

Abstract: Examples include application of a variable-sized content-defined chunking technique to a first data portion to identify a content-defined chunk boundary at least partially defining a remainder section, merging of the remainder section with a second data portion ordered before the first data portion to create a merged section, and application of the chunking technique to the merged section.
