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.
