Paths are specified as remote:bucket (or remote: for the lsd command.) You may put subdirectories in too, e.g. remote:bucket/path/to/dir.

Here is an example of making an QingStor configuration. First run

rclone config

This will guide you through an interactive setup process.

No remotes found - make a new one
n) New remote
r) Rename remote
c) Copy remote

This remote is called remote and can now be used like this

See all buckets

rclone lsd remote:

Make a new bucket

rclone mkdir remote:bucket

List the contents of a bucket

rclone ls remote:bucket

Sync /home/local/directory to the remote bucket, deleting any excess files in the bucket.

rclone sync -i /home/local/directory remote:bucket

--fast-list

This remote supports --fast-list which allows you to use fewer transactions in exchange for more memory. See the rclone docs for more details.

Multipart uploads

rclone supports multipart uploads with QingStor which means that it can upload files bigger than 5 GiB. Note that files uploaded with multipart upload don't have an MD5SUM.

Note that incomplete multipart uploads older than 24 hours can be removed with rclone cleanup remote:bucket just for one bucket rclone cleanup remote: for all buckets. QingStor does not ever remove incomplete multipart uploads so it may be necessary to run this from time to time.

Buckets and Zone

With QingStor you can list buckets (rclone lsd) using any zone, but you can only access the content of a bucket from the zone it was created in. If you attempt to access a bucket from the wrong zone, you will get an error, incorrect zone, the bucket is not in 'XXX' zone.

Authentication

There are two ways to supply rclone with a set of QingStor credentials. In order of precedence:

• Directly in the rclone configuration file (as configured by rclone config)
  • set access_key_id and secret_access_key
• Runtime configuration:
  • set env_auth to true in the config file
  • Exporting the following environment variables before running rclone
    • Access Key ID: QS_ACCESS_KEY_ID or QS_ACCESS_KEY
    • Secret Access Key: QS_SECRET_ACCESS_KEY or QS_SECRET_KEY

Restricted filename characters

The control characters 0x00-0x1F and / are replaced as in the default restricted characters set. Note that 0x7F is not replaced.

Invalid UTF-8 bytes will also be replaced, as they can't be used in JSON strings.

Standard Options

Here are the standard options specific to qingstor (QingCloud Object Storage).

--qingstor-env-auth

Get QingStor credentials from runtime. Only applies if access_key_id and secret_access_key is blank.

• Config: env_auth
• Env Var: RCLONE_QINGSTOR_ENV_AUTH
• Type: bool
• Default: false
• Examples:
  • "false"
    • Enter QingStor credentials in the next step
  • "true"
    • Get QingStor credentials from the environment (env vars or IAM)

--qingstor-access-key-id

QingStor Access Key ID Leave blank for anonymous access or runtime credentials.

• Config: access_key_id
• Env Var: RCLONE_QINGSTOR_ACCESS_KEY_ID
• Type: string
• Default: ""

--qingstor-secret-access-key

QingStor Secret Access Key (password) Leave blank for anonymous access or runtime credentials.

• Config: secret_access_key
• Env Var: RCLONE_QINGSTOR_SECRET_ACCESS_KEY
• Type: string
• Default: ""

--qingstor-endpoint

Enter an endpoint URL to connection QingStor API. Leave blank will use the default value "https://qingstor.com:443"

• Config: endpoint
• Env Var: RCLONE_QINGSTOR_ENDPOINT
• Type: string
• Default: ""

--qingstor-zone

Zone to connect to. Default is "pek3a".

• Config: zone
• Env Var: RCLONE_QINGSTOR_ZONE
• Type: string
• Default: ""
• Examples:
  • "pek3a"
    • The Beijing (China) Three Zone
    • Needs location constraint pek3a.
  • "sh1a"
    • The Shanghai (China) First Zone
    • Needs location constraint sh1a.
  • "gd2a"
    • The Guangdong (China) Second Zone
    • Needs location constraint gd2a.

Advanced Options

Here are the advanced options specific to qingstor (QingCloud Object Storage).

--qingstor-connection-retries

Number of connection retries.

• Config: connection_retries
• Env Var: RCLONE_QINGSTOR_CONNECTION_RETRIES
• Type: int
• Default: 3

--qingstor-upload-cutoff

Cutoff for switching to chunked upload

Any files larger than this will be uploaded in chunks of chunk_size. The minimum is 0 and the maximum is 5 GiB.

• Config: upload_cutoff
• Env Var: RCLONE_QINGSTOR_UPLOAD_CUTOFF
• Type: SizeSuffix
• Default: 200Mi

--qingstor-chunk-size

Chunk size to use for uploading.

When uploading files larger than upload_cutoff they will be uploaded as multipart uploads using this chunk size.

Note that "--qingstor-upload-concurrency" chunks of this size are buffered in memory per transfer.

If you are transferring large files over high-speed links and you have enough memory, then increasing this will speed up the transfers.

• Config: chunk_size
• Env Var: RCLONE_QINGSTOR_CHUNK_SIZE
• Type: SizeSuffix
• Default: 4Mi

--qingstor-upload-concurrency

Concurrency for multipart uploads.

This is the number of chunks of the same file that are uploaded concurrently.

NB if you set this to > 1 then the checksums of multipart uploads become corrupted (the uploads themselves are not corrupted though).

If you are uploading small numbers of large files over high-speed links and these uploads do not fully utilize your bandwidth, then increasing this may help to speed up the transfers.

• Config: upload_concurrency
• Env Var: RCLONE_QINGSTOR_UPLOAD_CONCURRENCY
• Type: int
• Default: 1

--qingstor-encoding

This sets the encoding for the backend.

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

• Config: encoding
• Env Var: RCLONE_QINGSTOR_ENCODING
• Type: MultiEncoder
• Default: Slash,Ctl,InvalidUtf8

Limitations

rclone about is not supported by the qingstor backend. Backends without this capability cannot determine free space for an rclone mount or use policy mfs (most free space) as a member of an rclone union remote.

See List of backends that do not support rclone about See rclone about
