A computer-implemented method for creating selective snapshots may include (1) determining that a snapshot has been taken of a volume of data that includes at least one file, (2) identifying a first attempted modification to a first block of the file, (3) determining, based on a block map of the file, that the first block falls within a scope of the snapshot, (4) copying the first block before the first attempted modification for use in the snapshot, (5) identifying a second attempted modification to a second block of the file, (6) determining, based on the block map of the file, that the second block does not fall within the scope of the snapshot, and (7) allowing the second attempted modification without first copying the second block for use in the snapshot. Various other methods, systems, and computer-readable media are also disclosed.
