Abstract: An archival storage of data backed up from a repository storage of a primary storage is maintained. Access to data stored in archival storage is limited by one or more access policies based on whether a corresponding data restore has been authorized. A request for specific data stored in the archival storage is received. The one or more access policies are automatically managed based on status and timing of one or more data restore authorizations for the specific data stored in the archival storage.

Abstract: One or more objects associated with a source storage is determined to be archived to a remote storage. A corresponding minimum expiration time is stored in nodes of a tree data structure associated with an archive that represents the archived data associated with the source storage. At least a portion of the tree data structure associated with the archive is traversed to identify one or more nodes associated with one or more archived objects having a corresponding expiration time expiring before an expiration time associated with the archive.

Abstract: An amount of expiration time extension for one or more objects associated with a first archive of a first snapshot of a source storage is determined based at least in part on a second data management policy associated with a second archive and one or more dynamically determined metrics. The first archive that includes the one or more objects is caused to be stored to a remote storage. At least a portion of content of the first archive is referenced by data chunks stored in a first chunk object of the remote storage and the first archive is associated with a first data management policy. Based on the determined amount of expiration time extension, an expiration time for the one or more objects associated with the first archive is stored in an archive metadata of the one or more objects associated with the first archive.

Abstract: Systems and methods for distributed and deduplicating a data store are provided herein. An exemplary method for distributed and deduplicating stored data, may include receiving an input data stream, segmenting the input data stream into chunks, creating a signature for each of the chunks, distributing each chunk to one of a plurality of containers, each container having a container identifier, and creating an index that includes a mapping of a chunk signature and a container identifier.
