THIN PROVISIONED CLONE

摘要

A unified system provides primary storage and in-line analytics-based data protection. Additional data intelligence and analytics gathered on protected data and prior analytics are stored in discovery points. The disclosed system implements multi-threaded log writes across rimary and restore nodes with write gathering across file systems; nested directories such as may be used for storing virtual machine files, where every subdirectory has an associated file system for snapshot purposes; and cloning objects on demand with background metadata and data migration.

主权项

1. A method for processing in a data-intelligent storage system that includes a primary node storing primary data and in-line analytics, a restore node storing further analytics and intelligence, comprising the steps of:
intercepting a request to clone a data object; thin provisioning a clone object; opening the clone object for access; and copying data to the clone object only upon the first to occur of:
(a) a subsequent access request for the clone object; and(b) as part of a background restore process.
