20100241615 | MITIGATION OF OBSOLESCENCE FOR ARCHIVAL SERVICES - The claimed subject matter relates to an architecture that can determine costs associated with updating file formats. In particular, the architecture can interface with a network-accessible data storage service in order to determine a cost-benefit to the data storage service for a wide variety of conversion scenarios applicable to the particular topology of the data storage service. For example, the cost-benefit can differ for storage services configured according to a client-server model relative to storage services configured according to a distributed topology. Regardless, the architecture can identify a legacy format, select a converter for converting the legacy format to the updated format, and then determine the cost-benefit for a variety of conversion or migration scenarios. | 09-23-2010 |
20110289289 | BACKUP AND RESTORE OF ITEMS USING BOUNDED CHECKPOINT AND LOG BUFFERS IN MEMORY - Architecture that is an efficient checkpoint process that performs backup and restore of checkpoint data items using bounded checkpoint buffers and log buffers in memory. Checkpoint processing can be performed using sequential inputs/outputs to a non-volatile storage medium (e.g., hard disk) on which the checkpoint files are persisted. Checkpoint processing is performed is in response to memory parameters that indicate the number or size of log entries accumulating in-memory relative to a memory threshold. In other words, given a bounded memory (e.g., cache), the rate of change of the log entries in the bounded memory triggers checkpoint processing. | 11-24-2011 |

20100241616 | PERPETUAL ARCHIVAL OF DATA - The claimed subject matter relates to a network-accessible, online data archival service with a data store for archiving data for clients of the archival service. The archival service can include an architecture that can facilitate perpetual sustainability and accessibility of data by conforming to a model. In particular, the model can describe or define a minimum set of extensible or pluggable components or modules needed to facilitate and guarantee sustainability of and accessibility to the data in perpetuity. | 09-23-2010 |
20100241617 | VIRTUAL SAFE DEPOSIT BOX FOR PERPETUAL DIGITAL ARCHIVAL - The claimed subject matter provides a system and/or a method that facilitates employing a safe deposit box that allows perpetual archiving of data. An online safe deposit box can store a portion of data, wherein the online safe deposit box is hosted by a data storage service provider. An archival model component can implement the online safe deposit box for perpetual archival of the portion of data. The archival model component can ensure at least one of the following: the online safe deposit retains the portion of data for a pre-defined duration; the portion of data within the online safe deposit box is accessible solely by an authorized entity; or the integrity of the portion of data is maintained, wherein the integrity is modified solely by an authorized user. | 09-23-2010 |
20100241980 | ONLINE VIRTUAL SAFE DEPOSIT BOX USER EXPERIENCE - The claimed subject matter provides a system and/or a method that facilitates seamless integration of a data storage service within an operating system (OS). An online safe deposit box can store a portion of data, wherein the online safe deposit box is hosted by a data storage service provider. A local operating system associated with a device can leverage a graphic user interface (GUI) to interact with a portion of data associated with the device. A map component can create a mapped drive that integrates the online safe deposit box within the local operating system to enable seamless data interaction between the local operating system and the online safe deposit box, wherein the data interaction is at least one of a data upload from the local operating system to the online safe deposit box or a data download from the online safe deposit box to the local operating system. | 09-23-2010 |
20100269164 | ONLINE SERVICE DATA MANAGEMENT - The claimed subject matter relates to an architecture that can facilitate automatic backup and versioning of online content. Appreciably, the architecture can relate to a network-accessible, online data archival service with a central backup data store for archiving online content published to disparate online services for clients of the archival service who are also clients of the disparate online service(s). The architecture can maintain rich content versioning, and can further provide additional services with respect to archived data such as restoration (to the original site, a disparate site, or a user device); synchronization between various online sites or between one or more sites and the backup data store; and conversion. The conversion can be employed in connection with backup, restore, or synch procedures and can apply to either a file format of the content or to a scope of the source of the content versus the scope of the destination. | 10-21-2010 |
20100274762 | DYNAMIC PLACEMENT OF REPLICA DATA - The claimed subject matter relates to systems and/or methodologies that facilitate distributed storage of data. A distributed file system can be implemented on storage nodes such that the system places multiple copies of data (e.g., replicas) on a variety of disparate storage nodes to guarantee availability of the data and minimize loss of the data. Storage nodes are dynamically evaluated to identify respective characteristics. In one example, the characteristics can include availability of a storage node, capacity of a storage node, data storage cost associated with a storage node, data transfer costs associated with a storage node, locality of a storage node, network topology, or user preferences associated with a storage node. The characteristics can be employed to generate optimal placements decisions. | 10-28-2010 |

20100312749 | SCALABLE LOOKUP SERVICE FOR DISTRIBUTED DATABASE - An embodiment of the invention is directed toward locating a file chunk in a distributed database. A hash partition containing a hash of a location of the file chunk is determined. A node hosting the hash partition is determined. A list of database partitions containing the file chunk is requested from the node. A list of database partitions is received. | 12-09-2010 |
20140324785 | EFFICIENT READ REPLICAS - A database system may receive a write request that specifies a modification to be made to a particular data record stored by the database system. A log record representing the modification to be made to the particular data record may be sent to a storage service of the database system. An indication (e.g., log record or other indication) that indicates a cached version of the particular data record stored in a read replica's cache is stale may be sent to a read replica. For a subsequent read of the particular data record received by the read replica, the read replica may request the particular data record from the storage service. | 10-30-2014 |
20140325116 | SELECTIVELY PERSISTING APPLICATION PROGRAM DATA FROM SYSTEM MEMORY TO NON-VOLATILE DATA STORAGE - Application program data stored in system memory may be selectively persisted. An indication may be provided to an application program that an application data object or a range of application data stored in system memory may be treated as persistent. Data backup may be enabled for the application data object or range of application data in the event of a system failure, copying the application data object or range of application data from system memory to non-volatile data storage. Upon recovery from a system failure, further data backup for the application data object or the range of application data may be disabled. In some embodiments, at least some of the application data object or range of application data may be recovered for the application program to access. Data backup for the application data object or the range of application data may also be re-enabled. | 10-30-2014 |
