This document aims to provide an introduction to Linux Logical Volume Manager (LVM); its working details and a set of changes that provide LVM with Time Chained Snapshots and Branching Capabilities. We further measure the read and write per- formance on Logical volumes created using LVM and the performance implications of adding support for time chained snapshots and branching capabilities.
