Abstract: A method for data management is described. The method may include generating a first snapshot of a first state of a data object, generating, using metadata associated with the first snapshot of the first state, a first hash value, and storing the first hash value to a blockchain. If the data object or device or system supporting the data object fails, then a failover procedure may be used to recover the data object. The method may include receiving an instruction to recover the first state of the data object using the first snapshot, retrieving the first hash value from the blockchain, comparing the first hash value retrieved from the blockchain to a second hash value of the metadata associated with the first snapshot, and determining, based at least in part on a result of the comparing, whether the first snapshot stored in the data management system is unmodified.
