Abstract
A method for using a change-recording feature to perform more effective backups includes generating an initial point-in-time copy of source data residing in a storage device. The method may then perform an initial backup of the initial point-in-time copy. As changes are made to the source data, the method may record changes made to the source data after the initial point-in-time copy is generated. These changes may be stored as incremental change data. At some point, the initial point-in-time copy may be updated using the incremental change data. In order to perform an incremental backup of the updated point-in-time copy, the method may query the incremental change data to determine which changes were used to update the point-in-time copy. The method may then perform an incremental backup of the updated point-in-time copy by backing up the changes designated in the incremental change data.
