Abstract
Ensuring data persistence and consistency in enterprise storage backup systems method and apparatus are disclosed. In one embodiment, a method includes creating a data log structure (e.g., a log file) on a storage device (e.g., a Serial ATA drive, a SCSI drive, a SAS drive, a storage are network, etc.) coupled to an application server to store a backup data generated by a filter module in a continuous backup environment and buffering the backup data generated by the filter module through a memory module that transfers the backup data to the data log structure on the storage device based on an occurrence of an event. The data log structure may be created by configuring a portion of the storage device as a dedicated resource available to the memory module to copy the backup data and the data log structure may be a file on the storage device coupled to the application server having the file system.
