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

Utility

[edit]

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), containerization, virtual machines (VMs), 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]
