INLINE SNAPSHOT DEDUPLICATION

Abstract: a data management system (dms) may select, prior to obtaining a first snapshot of a first virtual machine (vm) and from among one or more snapshots previously obtained by the dms, a second snapshot to use for deduplication of the first snapshot. the dms may obtain the first snapshot after selecting the second snapshot. obtaining the first snapshot may include writing a first subset of data blocks from the first vm to a snapshot file for the first snapshot based on the first subset of the data blocks from the first vm being different from a first corresponding subset of the second snapshot and refraining from writing a second subset of the data blocks from the first vm to the snapshot file for the first snapshot based on the second subset of the data blocks from the first vm matching a second corresponding subset of the second snapshot.
