Abstract
A computer-implemented method for securing storage space may include 1) identifying a block map that indicates whether each of a plurality of blocks within a storage system is to return zeroed data in response to read operations, 2) identifying a read operation directed to a block of the storage system that includes non-zeroed data, 3) determining, in response to identifying the read operation, that the block map indicates that the block is to return zeroed data in response to the read operation, and 4) returning zeroed data in response to the read operation based on determining that the block map indicates that the block is to return zeroed data. Various other methods, systems, and computer-readable media are also described.
