Abstract: Examples include the storage of format-aware filter format tracking states. Some examples include storage of a format tracking state for a format aware filter in a backup system in association with a backup object, access of the format tracking state from the backup system in response to detection of a potential continuation of a backup image, and applying the format-aware filter using the accessed format tracking state.

Abstract: Examples may include backup objects for fully provisioned volumes with thin lists of chunk signatures. Examples may generate one or more full lists of chunk signatures for the address space of a fully provisioned volume, compare each chunk signature of the full list to an unused region chunk signature representing a chunk of an unused region of the fully provisioned volume, generate metadata to indicate used regions of the fully provisioned volume, based on the comparisons, and generate from the one or more full lists, one or more thin lists omitting all chunk signatures determined to match the unused region chunk signature.

Abstract: Utilizing error correction (ECC) for secure secret sharing includes computing an encrypted key using a key and a number of random values, computing, based on a first ECC scheme, a key ECC for the encrypted key and the random values, and storing a number of key fragments on a number of storage servers, the number of key fragments includes the encrypted key, the random values, and the key ECC.
