## Usage

### minio

1. install & run minio, you need to configure your setting of minio in the main.go.

2. go run main.go



## Roadmap

### Client

- [x] Parse rsync://

- [x] Connect to rsync server

- [x] Hand shake

- [x] Send argument list

- [x] Fetch the file list

- [x] Request & download files



## Why we don't need block checksum?

Rsync requires random reading and writing of files to do the block exchange. But object storage does not support that.

rsync-os simplifies the rsync algorithm to avoid random reading and writing. When a file needs to be updated, we just download the entire file from the server and then replace it.
