Abstract
An operating method of a continuous data management (CDM) system includes duplicating data of a service node in real time in units of input/output system calls and integrally managing data, based on the duplicated data, by a data management policy module. The data management policy module selects management target data among the data of the service node and sets a management policy for the selected data.
Claims20
An operating method of a continuous data management (CDM) system, the operating method comprising:
- duplicating data of a service node in real time in units of input/output system calls in the form of a journal;
- and
- integrally managing data, based on the duplicated data, by a data management policy module,
- wherein the data management policy module selects management target data among the data of the service nodes and sets a management policy for the selected data.
1 more element
A data service system comprising:
- a plurality of service nodes at which changed data of the service node is transmitted to a continuous data management (CDM) by the CDM agent;
- and
- a CDM system configured to duplicate the data of each service node in real time in the form of a journal for a CDP period set by the data management policy to recover data in the units of input/output system call by file;
- and
- a CDM system configured to generate a snapshot, which is the same with a full copy data of each service node at a specific point in time, set by the data management policy using only the duplicated data for a CDP period without affecting the service node,
- wherein the CDM system duplicates data in the form of a journal of a corresponding service node in real time and includes the data management policy module configured to integrally manages data based on the duplicated data, and
- the data management policy module selects management target data and sets a management policy for the selected data.
