Overview

rsync is the de facto standard tool for fast, efficient file synchronisation, mirroring and backup. Its delta transfer algorithm sends only the parts of files that have changed, so repeated syncs of large trees finish in a fraction of the time and bandwidth of a full copy. In daemon mode, known as rsyncd, it listens on the network and exposes named modules, each mapped to a directory, that clients push files to or pull files from with the rsync protocol.

It suits teams who need a central backup target for servers and workstations, a mirror or distribution point for large datasets and build artifacts, or a scheduled off host copy of important directories, all running on infrastructure they own.

Why the cloudimg image

cloudimg delivers rsync in daemon mode fully configured as a hardened service, so a working rsync server answers on the network the moment the instance boots. The image is secure by default: where a naive rsync daemon exposes modules with no authentication, here the shipped module requires a user and password on every transfer, there is no anonymous access, and every transfer is chrooted inside its module directory. There is no baked credential: a unique module user and a long random password are generated on each instance's first boot and written to a root only file, with the module file store kept on a dedicated data disk. The base is fully patched with unattended security upgrades enabled, and every deployment is paired with a step by step deploy guide that also covers rsync over SSH, backed by 24/7 cloudimg support.
