Abstract
A security system includes a backup acquisition unit configured to store given information indicating states of backup data together with backup images generated from the backup data for each backup generation; and a determination unit configured to generate, when a predetermined timing comes, determination information for determining whether there is an abnormality in the stored backup data, based on a predetermined determination rule and the given information for each backup generation, and to output the generated determination information.
Claims11
A security system comprising:
- a first computer having data;
- and
- a second computer including a processor programmed to:
- store metadata indicating respective states of backup data of data of the first computer together with backup images generated from the backup data for a plurality of respective backup generations,
- store a plurality of predetermined determination rules, each determination rule corresponding to an event of the first computer and each determination rule specifying a parameter of the metadata,
- upon detecting an event of the first computer, automatically select a determination rule among the plurality of predetermined determination rules, based on the event detected of the first computer,
- generate, determination information that indicates whether there is an abnormality in a current generation of backup data, based on a difference of the parameter of the metadata specified by the automatically selected determination rule among between the current generation of metadata and respective metadata of different backup generations, and
- output the generated determination information.
A non-transitory computer-readable storage medium that stores a computer program that causes a first computer to function as a security system, the computer program causing the computer to execute steps comprising:
- storing metadata indicating respective states of backup data of data of a second computer together with backup images generated from the backup data for a plurality of respective backup generations;
- and
- storing a plurality of predetermined determination rules, each determination rule corresponding to an event of the second computer and each determination rule specifying a parameter of the metadata;
- upon detecting an event of the second computer, automatically selecting a determination rule among the plurality of predetermined determination rules, based on the event detected of the second computer;
- generating, determination information that indicates whether there is an abnormality in a current generation of backup data, based on a difference of the parameter of the metadata specified by the automatically selected determination rule between the current generation of metadata and respective metadata of different backup generations;
- and
- outputting the generated determination information.
A data diagnostic method of diagnosing safety of data used by a business computer, the data diagnostic method comprising:
- storing metadata indicating respective states of backup data of the business computer together with backup images generated from the backup data for a plurality of respective backup generations;
- storing a plurality of predetermined determination rules, each determination rule corresponding to an event of the business computer and each determination rule specifying a parameter of the metadata;
- upon detecting an event of the business computer, automatically selecting a determination rule among the plurality of predetermined determination rules, based on the event detected of the business computer;
- generating, determination information that indicates whether there is an abnormality in a current generation of backup data, based on a difference of the parameter of the metadata specified by the automatically selected determination rule between the current generation of metadata and respective metadata of different backup generations;
- and
- outputting the generated determination information.
