Method and system for virtual on-demand recovery
First Claim
1. A method of data recovery in a first computer processing environment, where data has been stored in a data store different from a data source in the first processing environment, the method comprising:
- initiating a data recovery operation;
recovering given data to a former state as reflected in a data store, wherein the recovery comprises;
presenting a structure of the given data to a user associated with a database so that, from a point-of-view of the user, the database is recovered prior to fully recovering the given data;
if an access request is for data that has not been recovered, promptly recovering the data requested; and
continuing to recover the given data; and
enabling a database application to continue accessing or updating the given data during the recovery.

Abstract
A data management system (“DMS”) provides an automated, continuous, real-time, substantially no downtime data protection service to one or more data sources. A host driver embedded in an application server captures real-time data transactions, preferably in the form of an event journal. The driver functions to translate traditional file/database/block I/O and the like into a continuous, application-aware, output data stream. The host driver includes an event processor that can perform a recovery operation to an entire data source or a subset of the data source using former point-in-time data in the DMS. The recovery operation may have two phases. First, the structure of the host data in primary storage is recovered to the intended recovering point-in-time. Thereafter, the actual data itself is recovered. The event processor enables such data recovery in an on-demand manner, by allowing recovery to happen simultaneously while an application accesses and updates the recovering data.

9. An apparatus for providing a data recovery service in a first processing environment, where data has been stored in a data store different from a data source in the first processing environment, comprising:
-
a processor; and code executable by the processor to; initiate a data recovery operation; recover given data to a former state as reflected in a data store, wherein the recovery comprises; presenting a structure of the given data to a user associated with a database so that, from a point-of-view of the user, the database is recovered prior to fully recovering the given data; if an access request is for data that has not been recovered, promptly recovering the data requested; and continuing to recover the given data; and enable a database application to continue accessing or updating the given data during the recovery. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
