casync ( content-addressable synchronisation) is a Linux software utility designed to distribute frequently-updated file system images over the Internet. [2] [3]

Contents

Utility

According to the creator Lennart Poettering, casync is inspired by rsync and Git, [4] as well as tar. [5] casync is aimed to be used for Internet of things (IoT), container, virtual machine (VM), portable services, and operating system (OS) images, as well as backups and home directory synchronization. [3] casync splits images into variable size segments, uses sha256 checksums, and aims to work with content delivery networks (CDNs). [5] [4] Available for Linux only, [4] packages are available for Ubuntu, Fedora and Arch Linux. [5]
