Abstract
A method and system for write tracking for block based backup that supports multiple block based backup applications. The method includes creating a first bitmap for a first block based backup application by the block based backup engine, creating a second bitmap for a second block based backup application by the block based backup engine. In response to receiving a request from a block based backup application to start a backup a check is made whether the request indicates a full backup or incremental backup for the first block based backup application. A merging of the bitmaps for block based backup applications is performed such that the performance of the requested backup is taken into account for the first backup application without adversely affecting the tracking of the block based backup of other backup applications.
