Data set capture management with forecasting

摘要

A set of virtualized computing services may include multiple types of virtualized data store differentiated by characteristics such as latency, throughput, durability and cost. A sequence of captures of a data set from one data store to another may be scheduled to achieve a variety of virtualized computing service user and provider goals such as lowering a probability of data loss, lowering costs, and computing resource load leveling. Data set captures may be scheduled according to policies specifying fixed and flexible schedules and conditions including flexible scheduling windows, target capture frequencies, probability of loss targets and/or cost targets. Capture lifetimes may also be managed with capture retention policies, which may specify fixed and flexible lifetimes and conditions including cost targets. Such data set capture policies may be specified with a Web-based administrative interface to a control plane of the virtualized computing services.

主权项

1. A computerized system facilitating data set capture management, comprising:
a first data store configured at least to maintain a data set; a second data store capable at least of maintaining a plurality of captures of the data set for later inspection, the plurality of captures corresponding to representations of the data set at selected moments in time; a network communicatively coupling at least the first data store and the second data store; a storage policy enforcement component configured to, at least: schedule at least one capture of the data set in accordance with at least one data set capture policy; forecast at least one utilization load of a set of components of the computerized system including the first data store and the network; and schedule at least one pre-capture transfer of at least a portion of the data set prior to said at least one capture, the scheduling of said at least one pre-capture transfer arranged at least to optimize said at least one utilization load of the set of components of the computerized system, the optimization based at least in part on the schedule of said at least one capture and the forecast of said at least one utilization load; and one or more processors collectively configured at least to facilitate the first data store, the second data store and the storage policy enforcement component.
