An Efficient Backup and Replication of Storage - Takashi Hoshino, Cybozu Labs Inc.

We propose an algorithm and its implementation for efficient backup and replication of storage, called 'WalB'. The word 'WalB' means Block-level Write-Ahead Logging. A WalB device stores 'redo logs' in another block device, never 'undo logs'. This achieves small performance overhead. The logs allows you incremental backup and asynchronous replication without full-scan nor random read of the device. The current implementation consists of a Linux kernel module to provide wrapper block devices and its related tools to control them. Its source code are available on GitHub repository under the GPLv2 or v3 license.

The expected audience of this talk are:
(1) people who search for a good solution for storage backup and replication.
(2) Linux kernel developers who are working on block devices or file systems.
(3) software engineers who are interested in storage technology.
