NSync Servers

Analyzer -(nbus)-> Sync -(nbus)-> Storage

Components

• CLI/GUI:

  On top of the REST API, provides access to configuration setup and operation status.

• REST API:

  Provides access to Application resources through a HTTP RESTful API

• Kernel Facade:

  Provide entry point for implement Use Cases operations. Execute operations asynchronously and provide access to Kernel readonly data structures (metadata & metrics)

• Analyzer:

  Analyzes local folders - watch directories trees for files changes and do full folder scan, firing LocalFile event.

• Sync:

  Consumes the LocalFile events, updates local file metadata information (file path, md5, last modification, size), and decide whether to fire FileTransfer events.

• Storage:

  Support for specific storage backend - do the actual file transfer. Fires TransferStatus events.

• Metadata:

  Keeps metadata information about the Filesystems and files within the system. Provides a readonly access and can be modified through asynchronous signals

• NBus:

  Message bus used for communication between the modules above. Takes care of coroutine initialization and so on.

Open Question:

• Sanitization: Removing old files • File transfer / storage optmization • File recovery mechanism
