In order to prepare them for the next class, it is important to be able to return them to its original state as soon as possible. The Logical Volume Manager snapshots are useful in these cases.The Logical Volume Manager (LVM) is a method that has been used successfully on Linux for many years and managing storage in a flexible way. Instead of working with fixed storage allocation units, LVM work with versatile volumes that can be extended or reduced very easily. These volumes offer also other benefits, like the snapshots."}
