System and method for hybrid virtual machine monitor file system operations
Abstract:
A system and method for hybrid virtual machine monitor system is provided. A first operating system uses a file system to manage data storage and retrieval within a data storage area. A second operating system, which is not compatible with the first operating system's file system, executes a management application backup utility. The first operating system includes a filter driver that sends logical block addresses, which correspond to data reads/writes, to the management application backup utility. In turn, the management application backup utility uses the logical block addresses to perform operations on the data storage locations. In one embodiment, the management application backup utility performs actions on the data storage area, such as a disk defragmentation, and subsequently sends data location changes to the filter driver. In this embodiment, the filter driver instructs the first operating system's file system to update its translation tables based upon the data location changes.
