Sia	Remote for Sia Decentralized Cloud	2019-10-02

{{< icon "fa fa-globe" >}} Sia

Sia (sia.tech) is a decentralized cloud storage platform
based on the blockchain technology.
With rclone you can use it like any other remote filesystem or mount Sia folders
locally. The technology behind it involves a number of new concepts such as
Siacoins and Wallet, Blockchain and Consensus, Renting and Hosting, and so on.
If you are new to it, you'd better first familiarize yourself using their
excellent support documentation.

Introduction

Before you can use rclone with Sia, you will need to have a running copy of
Sia-UI or siad (the Sia daemon) locally on your computer or on local
network (e.g. a NAS). Please follow the Get started
guide and install one.

rclone interacts with Sia network by talking to the Sia daemon via HTTP API
which is usually available on port 9980. By default you will run the daemon
locally on the same computer so it's safe to leave the API password blank
(the API URL will be http://127.0.0.1:9980 making external access impossible).

However, if you want to access Sia daemon running on another node, for example
due to memory constraints or because you want to share single daemon between
several rclone and Sia-UI instances, you'll need to make a few more provisions:

• Ensure you have Sia daemon installed directly or in
  a docker container
  because Sia-UI does not support this mode natively.
• Run it on externally accessible port, for example provide --api-addr :9980
  and --disable-api-security arguments on the daemon command line.
• Enforce API password for the siad daemon via environment variable
  SIA_API_PASSWORD or text file named apipassword in the daemon directory.
• Set rclone backend option api_password taking it from above locations.

Notes:

1. If your wallet is locked, rclone cannot unlock it automatically.
   You should either unlock it in advance by using Sia-UI or via command line
   siac wallet unlock.
   Alternatively you can make siad unlock your wallet automatically upon
   startup by running it with environment variable SIA_WALLET_PASSWORD.
2. If siad cannot find the SIA_API_PASSWORD variable or the apipassword file
   in the SIA_DIR directory, it will generate a random password and store in the
   text file named apipassword under YOUR_HOME/.sia/ directory on Unix
   or C:\Users\YOUR_HOME\AppData\Local\Sia\apipassword on Windows.
   Remember this when you configure password in rclone.
3. The only way to use siad without API password is to run it on localhost
   with command line argument --authorize-api=false, but this is insecure and
   strongly discouraged.

Configuration

Here is an example of how to make a sia remote called mySia.
First, run:

 rclone config

This will guide you through an interactive setup process:

No remotes found - make a new one
n) New remote
s) Set configuration password
q) Quit config
n/s/q> n
name> mySia
Type of storage to configure.
Enter a string value. Press Enter for the default ("").
Choose a number from below, or type in your own value
...
29 / Sia Decentralized Cloud
   \ "sia"
...
Storage> sia
Sia daemon API URL, like http://sia.daemon.host:9980.
Note that siad must run with --disable-api-security to open API port for other hosts (not recommended).
Keep default if Sia daemon runs on localhost.
Enter a string value. Press Enter for the default ("http://127.0.0.1:9980").
api_url> http://127.0.0.1:9980
Sia Daemon API Password.
Can be found in the apipassword file located in HOME/.sia/ or in the daemon directory.
y) Yes type in my own password
g) Generate random password
n) No leave this optional password blank (default)
y/g/n> y
Enter the password:
password:
Confirm the password:
password:
Edit advanced config?
y) Yes
n) No (default)
y/n> n
--------------------
[mySia]
type = sia
api_url = http://127.0.0.1:9980
api_password = *** ENCRYPTED ***
--------------------
y) Yes this is OK (default)
e) Edit this remote
d) Delete this remote
y/e/d> y

Once configured, you can then use rclone like this:

• List directories in top level of your Sia storage

rclone lsd mySia:

• List all the files in your Sia storage

rclone ls mySia:

• Upload a local directory to the Sia directory called backup

rclone copy /home/source mySia:backup

Standard options

Here are the standard options specific to sia (Sia Decentralized Cloud).

--sia-api-url

Sia daemon API URL, like http://sia.daemon.host:9980.
Note that siad must run with --disable-api-security to open API port for other hosts (not recommended).
Keep default if Sia daemon runs on localhost.

• Config: api_url
• Env Var: RCLONE_SIA_API_URL
• Type: string
• Default: "http://127.0.0.1:9980"

--sia-api-password

Sia Daemon API Password.
Can be found in the apipassword file located in HOME/.sia/ or in the daemon directory.

NB Input to this must be obscured - see rclone obscure.

• Config: api_password
• Env Var: RCLONE_SIA_API_PASSWORD
• Type: string
• Default: ""

Advanced options

Here are the advanced options specific to sia (Sia Decentralized Cloud).

--sia-user-agent

Siad User Agent
Sia daemon requires the 'Sia-Agent' user agent by default for security

• Config: user_agent
• Env Var: RCLONE_SIA_USER_AGENT
• Type: string
• Default: "Sia-Agent"

--sia-encoding

This sets the encoding for the backend.

See: the encoding section in the overview for more info.

• Config: encoding
• Env Var: RCLONE_SIA_ENCODING
• Type: MultiEncoder
• Default: Slash,Question,Hash,Percent,Del,Ctl,InvalidUtf8,Dot

{{< rem autogenerated options stop >}}

Limitations

• Modification times not supported
• Checksums not supported
• rclone about not supported
• rclone can work only with Siad or Sia-UI at the moment,
  the SkyNet daemon is not supported yet.
• Sia does not allow control characters or symbols like question and pound
  signs in file names. rclone will transparently encode
  them for you, but you'd better be aware
