Abstract

A data management system or “DMS” provides an automated, continuous, real-time data protection service to one or more data sources associated with a set of application host serves. To facilitate the service, a host driver embedded in an application server captures real-time data transactions. When a data protection command for a given data source is forwarded to a host driver, an event processor enters into an initial upload state. During this state, the event processor gathers a list of data items to be protected and creates a data list. Then, the event processor moves the data to a DMS core to create initial baseline data. The upload is a stream of application-aware data chunks that are attached to upload events. A resynchronization state is entered when there is a suspicion that the state of the data in the host is out-of-sync with the state of the most current data in the DMS.

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a continuation of U.S. patent application Ser. No. 10 / 862,971, filed Jun. 8, 2004, titled METHOD AND SYSTEM FOR NO DOWNTIME RESYNCHRONIZATION FOR REAL-TIME, CONTINUOUS DATA PROTECTION. U.S. patent application Ser. No. 10 / 862,971, U.S. Pat. No. 7,096,392, and U.S. Pat. No. 7,565,661 are incorporated herein by reference.BACKGROUND OF THE INVENTION

[0002] 1. Technical Field

[0003] The present invention relates generally to enterprise data protection.

[0004] 2. Background of the Related Art

[0005] A critical information technology (IT) problem is how to cost-effectively deliver network wide data protection and rapid data recovery. In 2002, for example, companies spent an estimated $50 B worldwide managing data backup / restore and an estimated $30 B in system downtime costs. The “code red” virus alone cost an estimated $2.8 B in downtime, data loss, and recovery. The reason for these staggering costs is simple-traditional schedule b...
