Hot File system Backup using Ext4 Snapshots

by Shardul for The Linux Foundation

A hot backup, also called a dynamic backup, is a backup performed on data even though it is actively accessible to users and may currently be in a state of being updated. Snapshots is one of the desirable features at the file system level, with Btrfs already having it and Ext4 snapshots project is already under way. Ext4 Snapshots can be effectively leveraged to implement hot File System Backup on another device.
