DATABASE APPLICATION BACKUP IN SINGLE SNAPSHOT FOR MULTIPLE APPLICATIONS

摘要

An information management system according to certain aspects may be configured to generate a snapshot of data relating to a plurality of applications. Data generated by the plurality of applications may be stored in a logical volume in primary storage. The system may include a plurality of data agents including a database data agent associated with a database application that can be configured to back up one or more log files of a database log separately from data of the database application. The system may also include a snapshot manager configured to: in response to receiving notifications from the plurality of data agents that the associated applications are in consistent states, obtain a snapshot of the logical volume; generate mapping information between a particular application of the plurality of applications and a portion of the snapshot relating to the particular application; and truncate the database log of the database application.

1. An information management system configured to generate a snapshot of data relating to a plurality of applications, the system comprising:
a plurality of data agents executing at least in part on a client computing device, each data agent being associated with at least one of a plurality of applications executing on the client computing device, wherein:
data generated by the plurality of applications is stored in a logical volume in primary storage; andthe plurality of data agents comprises at least a database data agent associated with a database application, the database data agent configured to back up one or more log files of a database log of the database application separately from data of the database application; and a snapshot manager executing on computer hardware and configured to:
detect the plurality of applications executing on the client computing device;in response to receiving notifications from the plurality of data agents that the associated applications are in consistent states, obtain a snapshot of the logical volume that comprises the data generated by the plurality of applications;generate mapping information between a particular one of the plurality of applications and a portion of the snapshot relating to the particular one of the plurality of applications, the mapping information comprising database application mapping information between the database application and a portion of the snapshot relating to the database application;copy the snapshot to the secondary storage using one or more media agents; andtruncate the database log of the database application.
