A cloud file system management capability provides a probabilistic eviction scheme for evicting data blocks from storage volumes of cloud storage services in advance of storage deadlines by which the data blocks are to be removed from the storage volumes. A cloud file system management capability enables dynamic adaptation of the storage volume sizes of the storage volumes of the cloud storage services.

Abstract: Apparatus, systems, and methods may operate to determine a proximate save time difference between a target version of electronic content and a next (proximate in time and newer) version of the electronic content. An aged save time difference may be determined as the time difference between the current time and either one of the target version or the next version. The target version of the electronic content may be pruned from a plurality of revisions of the electronic content if the proximate save time difference is less than a selected fraction of the aged save time difference. The plurality of revisions, less the pruned revisions, may be displayed along a historical time line as part of a graphical user interface.

Abstract: Aspects of the invention provide a solution for determining a storage location for a data item from among a set of persistent storage locations having varying access speeds. Each data item is associated with a score that is based on the frequency with which the data item has been accessed, as well as possible other factors such as open time and/or close time of the data item, the amount of data in the data item, the period from the last time the data item was closed to the next time that the data item is opened and/or the total amount of data in the data item. Data items with high scores relative to other data items are assigned to faster access storage location while data items with lower scores are assigned to slower access storage locations.

Abstract: In some implementations, a method for archiving emails includes determining an email file presented in an email application through a Graphical User Interface (GUI) has been selected in response to a user moving the email file into a virtual folder in the GUI.

In response to moving the email file into the virtual folder, a second file in a second file format native to a second application different from the email application is automatically generated. The second file has, when presented in the second application through the GUI, a second presentation format substantially similar to the first presentation format. Data in the email file is stored in the second file.

Abstract: Reclaiming data space by rewriting metadata is disclosed. It is determined that fewer than all of the previous version data included in a write is required to be retained, e.g., beyond a continuous data protection window.

Other blocks become eligible for reclamation.

Abstract: A content platform (or “cluster”) that comprises a redundant array of independent nodes is logically partitioned. Using a web-based interface, an administrator defines one or more “tenants” within the cluster, wherein a tenant has a set of attributes: namespaces, administrative accounts, data access accounts, and a permission mask. A namespace is a logical partition of the cluster that serves as a collection of objects typically associated with at least one defined application. Each namespace has a private file system with respect to other namespaces. This approach enables a user to segregate cluster data into logical partitions. Using the administrative interface, a namespace associated with a given tenant is selectively configured without affecting a configuration of at least one other namespace in the set of namespaces. One configuration option is a “disposition service” that, once enabled for a namespace, automatically deletes objects that were once under retention and whose retention time has expired.

Abstract: In an image forming apparatus, a first document manager stores image data in an image storage device, associates the image data with a first identifier, outputs the image data via an image output device when the first identifier is specified via an operation device, and deletes the image data from the image storage device when a first condition is satisfied. A second document manager associates the image data with a second identifier, outputs the second identifier via the image output device, and outputs the image data via the image output device when the second identifier is input via an image input device. The first document manager does not delete the image data from the image storage device and prohibits the operation device from specifying the first identifier when the image data is associated with both the first and second identifiers.

Abstract: A database spread over multiple nodes allows each node to store a journal recording changes made to the database and also allows a journaling component to manage the memory space available for journaling. Two threshold size values may be specified for the journal. The first threshold value specifies a journal size at which to being pruning the journal on a given node. A journal pruning algorithm may be used to identify journal entries that may be removed. For example, once a given transaction completes (i.e., commits) the journal entries related to that transaction may be pruned from the journal. The second threshold value specifies the maximum size of the journal. After reaching this size, journal entries may be written to disk instead of the in-memory journal.
