Abstract: Technology is disclosed for managing data in a distributed processing system (“the technology”). In various embodiments, the technology pushes “cold” data from a primary storage of the distributed processing system to a backup storage thereby maximizing the usage of the space on the primary storage to store “hot” data on which most data processing activities are performed in the distributed processing system. The cold data is retrieved from the backup storage into the primary storage on demand, for example, upon receiving an access request from a client. While the primary storage stores the data in a format specific to the distributed processing system, the backup storage stores the data in a different format, for example, format corresponding to the type of backup storage.

Abstract: Technology is disclosed for managing data in a distributed file system (“the technology”). The technology can gather metadata information associated with the data stored within a first file system, store the metadata information in association with a data identifier within a second file system, retrieve the stored metadata information using the data identifier from within the second file system and locate and retrieve the data associated with the metadata information from within first file system.
