A method of volume compressed header identification includes reading, by a processing device of a host, compressible data on a sector of a storage volume of a storage array. The method further includes compressing the compressible data to generate compressed data for the sector. The method further includes adding, by the processing device of the host, metadata associated with the storage volume to the compressed data. The method further includes writing the compressed data, including the added metadata, to the sector of the storage volume of the storage array.

Optimizing I/O operations for compressed data

An illustrative method includes a data protection system identifying one or more input operations and one or more output operations performed between a source and a storage system, identifying an anomaly in a relationship between the one or more input operations and the one or more output operations, and determining, based on the identifying of the anomaly, that the storage system is possibly being targeted by a security threat.

Inter-I/O relationship based detection of a security threat to a storage system

Protecting an encryption key for data stored in a storage system that includes a plurality of storage devices, including: reading, from at least a majority of the storage devices, a portion of an apartment key; reconstructing the apartment key using the portions of the apartment key read by the majority of the storage devices; unlocking the main portion of each of the storage devices utilizing the apartment key; reading, from the main portion of one of the storage devices, a portion of a third-party resource access key; requesting, from the third-party resource utilizing the third-party resource access key, an encryption key; receiving, from the third-party resource, the encryption key; and decrypting the data stored on the storage devices utilizing the encryption key.
