Globalization causes the backup window shrunk sharply. How to backup data efficiently and effectively is one of the most urgent questions today. To solve the above problem, Blue Whale Backup System(BWBS) is designed and implemented. BWBS may backup different file systems and databases by the block-level backup method. And, because the block-level backup may provide backup with less granularity, so with the comparison of the file-level backup, the block-level backup has better improvement at two aspects of backup performance and space use. BWBS uses the policy-driven method to backup automatically in order to implement management automatization.
