---------------------------------------

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

Here is an example of making an s3 configuration.  First run

    rclone config

This will guide you through an interactive setup process.

Remote config

[remote]
env_auth = false
access_key_id = access_key
secret_access_key = secret_key
region = us-east-1
endpoint = 
location_constraint = 
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```

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 /home/local/directory remote:bucket

### Modified time ###

The modified time is stored as metadata on the object as
`X-Amz-Meta-Mtime` as floating point since the epoch accurate to 1 ns.

### Multipart uploads ###

rclone supports multipart uploads with S3 which means that it can
upload files bigger than 5GB. Note that files uploaded with multipart
upload don't have an MD5SUM.

### Buckets and Regions ###

With Amazon S3 you can list buckets (`rclone lsd`) using any region,
but you can only access the content of a bucket from the region it was
created in.  If you attempt to access a bucket from the wrong region,
you will get an error, `incorrect region, the bucket is not in 'XXX'
region`.

### Authentication ###
There are two ways to supply `rclone` with a set of AWS
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: `AWS_ACCESS_KEY_ID` or `AWS_ACCESS_KEY`
     - Secret Access Key: `AWS_SECRET_ACCESS_KEY` or `AWS_SECRET_KEY`
   - Running `rclone` on an EC2 instance with an IAM role

If none of these option actually end up providing `rclone` with AWS
credentials then S3 interaction will be non-authenticated (see below).

### Specific options ###

Here are the command line options specific to this cloud storage
system.

#### --s3-acl=STRING ####

Canned ACL used when creating buckets and/or storing objects in S3.

For more info visit the [canned ACL docs](http://docs.aws.amazon.com/AmazonS3/latest/dev/acl-overview.html#canned-acl).

#### --s3-storage-class=STRING ####

Storage class to upload new objects with.

Available options include:

 - STANDARD - default storage class
 - STANDARD_IA - for less frequently accessed data (e.g backups)
 - REDUCED_REDUNDANCY (only for noncritical, reproducible data, has lower redundancy)

### Anonymous access to public buckets ###

If you want to use rclone to access a public bucket, configure with a
blank `access_key_id` and `secret_access_key`.  Eg

```
No remotes found - make a new one
n) New remote
q) Quit config
n/q> n
name> anons3
What type of source is it?
Choose a number from below
 1) amazon cloud drive
 2) b2
 3) drive
 4) dropbox
 5) google cloud storage
 6) swift
 7) hubic
 8) local
 9) onedrive
10) s3
11) yandex
type> 10
Get AWS credentials from runtime (environment variables or EC2 meta data if no env vars). Only applies if access_key_id and secret_access_key is blank.
Choose a number from below, or type in your own value
 * Enter AWS credentials in the next step
 1) false
 * Get AWS credentials from the environment (env vars or IAM)
 2) true
env_auth> 1
AWS Access Key ID - leave blank for anonymous access or runtime credentials.
access_key_id>
AWS Secret Access Key (password) - leave blank for anonymous access or runtime credentials.
secret_access_key>
...
```

Then use it as normal with the name of the public bucket, eg

    rclone lsd anons3:1000genomes

You will be able to list and copy data but not upload it.

### Ceph ###

Ceph is an object storage system which presents an Amazon S3 interface.

To use rclone with ceph, you need to set the following parameters in
the config.

```
access_key_id = Whatever
secret_access_key = Whatever
endpoint = https://ceph.endpoint.goes.here/
region = other-v2-signature
```

Note also that Ceph sometimes puts `/` in the passwords it gives
users.  If you read the secret access key using the command line tools
you will get a JSON blob with the `/` escaped as `\/`.  Make sure you
only write `/` in the secret access key.

Eg the dump from Ceph looks something like this (irrelevant keys
removed).

```
{
    "user_id": "xxx",
    "display_name": "xxxx",
    "keys": [
        {
            "user": "xxx",
            "access_key": "xxxxxx",
            "secret_key": "xxxxxx\/xxxx"
        }
    ],
}
```

Because this is a json dump, it is encoding the `/` as `\/`, so if you
use the secret key as `xxxxxx/xxxx`  it will work fine.

### Minio ###

[Minio](https://minio.io/) is an object storage server built for cloud application developers and devops.

It is very easy to install and provides an S3 compatible server which can be used by rclone.

To use it, install Minio following the instructions from the web site.

When it configures itself Minio will print something like this

```
AccessKey: WLGDGYAQYIGI833EV05A  SecretKey: BYvgJM101sHngl2uzjXS/OBF/aMxAN06JrJ3qJlF Region: us-east-1

Minio Object Storage:
     http://127.0.0.1:9000
     http://10.0.0.3:9000

Minio Browser:
     http://127.0.0.1:9000
     http://10.0.0.3:9000
```

These details need to go into `rclone config` like this.  Note that it
is important to put the region in as stated above.

```
env_auth> 1
access_key_id> WLGDGYAQYIGI833EV05A
secret_access_key> BYvgJM101sHngl2uzjXS/OBF/aMxAN06JrJ3qJlF   
region> us-east-1
endpoint> http://10.0.0.3:9000
location_constraint> 
server_side_encryption>
```

Which makes the config file look like this

```
[minio]
env_auth = false
access_key_id = WLGDGYAQYIGI833EV05A
secret_access_key = BYvgJM101sHngl2uzjXS/OBF/aMxAN06JrJ3qJlF
region = us-east-1
endpoint = http://10.0.0.3:9000
location_constraint = 
server_side_encryption = 
```

Minio doesn't support all the features of S3 yet.  In particular it
doesn't support MD5 checksums (ETags) or metadata.  This means rclone
can't check MD5SUMs or store the modified date.  However you can work
around this with the `--size-only` flag of rclone.

So once set up, for example to copy files into a bucket

    rclone --size-only copy /path/to/files minio:bucket
