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 = XXX
secret_access_key = YYY
region = us-east-1
endpoint = 
location_constraint = 
acl = private
server_side_encryption = 
storage_class = 
--------------------
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

### --fast-list ###

This remote supports `--fast-list` which allows you to use fewer
transactions in exchange for more memory. See the [rclone
docs](/docs/#fast-list) for more details.

### 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 *both* with
multipart upload *and* through crypt remotes do not have MD5 sums.

### 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`. `session_token` can be
     optionally set when using AWS STS.
 - 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`
     - Session Token: `AWS_SESSION_TOKEN`
   - Running `rclone` in an ECS task with an IAM role
   - 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).

### S3 Permissions ###

When using the `sync` subcommand of `rclone` the following minimum 
permissions are required to be available on the bucket being written to:

* `ListBucket`
* `DeleteObject`
* `GetObject`
* `PutObject`
* `PutObjectACL`

Example policy:

```
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::USER_SID:user/USER_NAME"
            },
            "Action": [
                "s3:ListBucket",
                "s3:DeleteObject",
                "s3:GetObject",
                "s3:PutObject",
                "s3:PutObjectAcl"
            ],
            "Resource": [
              "arn:aws:s3:::BUCKET_NAME/*",
              "arn:aws:s3:::BUCKET_NAME"
            ]
        }
    ]
}
```

Notes on above:

1. This is a policy that can be used when creating bucket. It assumes
   that `USER_NAME` has been created.
2. The Resource entry must include both resource ARNs, as one implies 
   the bucket and the other implies the bucket's objects.

For reference, [here's an Ansible script](https://gist.github.com/ebridges/ebfc9042dd7c756cd101cfa807b7ae2b) 
that will generate one or more buckets that will work with `rclone sync`.

### Glacier ###

You can transition objects to glacier storage using a [lifecycle policy](http://docs.aws.amazon.com/AmazonS3/latest/user-guide/create-lifecycle.html).
The bucket can still be synced or copied into normally, but if rclone
tries to access the data you will see an error like below.

    2017/09/11 19:07:43 Failed to sync: failed to open source object: Object in GLACIER, restore first: path/to/file

In this case you need to [restore](http://docs.aws.amazon.com/AmazonS3/latest/user-guide/restore-archived-objects.html)
the object(s) in question before using rclone.

### 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](https://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/ECS 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](https://ceph.com/) is an open source unified, distributed
storage system designed for excellent performance, reliability and
scalability.  It has an S3 compatible object storage interface.

To use rclone with Ceph, configure as above but leave the region blank
and set the endpoint.  You should end up with something like this in
your config:


```
[ceph]
type = s3
env_auth = false
access_key_id = XXX
secret_access_key = YYY
region = 
endpoint = https://ceph.endpoint.example.com
location_constraint = 
acl = 
server_side_encryption = 
storage_class = 
```

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.

### Dreamhost ###

Dreamhost [DreamObjects](https://www.dreamhost.com/cloud/storage/) is
an object storage system based on CEPH.

To use rclone with Dreamhost, configure as above but leave the region blank
and set the endpoint.  You should end up with something like this in
your config:

```
[dreamobjects]
env_auth = false
access_key_id = your_access_key
secret_access_key = your_secret_key
region =
endpoint = objects-us-west-1.dream.io
location_constraint =
acl = private
server_side_encryption =
storage_class =
```


### DigitalOcean Spaces ###

[Spaces](https://www.digitalocean.com/products/object-storage/) is an [S3-interoperable](https://developers.digitalocean.com/documentation/spaces/) object storage service from cloud provider DigitalOcean.

To connect to DigitalOcean Spaces you will need an access key and secret key. These can be retrieved on the "[Applications & API](https://cloud.digitalocean.com/settings/api/tokens)" page of the DigitalOcean control panel. They will be needed when promted by `rclone config` for your `access_key_id` and `secret_access_key`.

When prompted for a `region` or `location_constraint`, press enter to use the default value. The region must be included in the `endpoint` setting (e.g. `nyc3.digitaloceanspaces.com`). The defualt values can be used for other settings.

Going through the whole process of creating a new remote by running `rclone config`, each prompt should be answered as shown below:

```
Storage> s3
env_auth> 1
access_key_id> YOUR_ACCESS_KEY
secret_access_key> YOUR_SECRET_KEY
region> 
endpoint> nyc3.digitaloceanspaces.com
location_constraint> 
acl> 
storage_class> 
```

The resulting configuration file should look like:

```
[spaces]
type = s3
env_auth = false
access_key_id = YOUR_ACCESS_KEY
secret_access_key = YOUR_SECRET_KEY
region = 
endpoint = nyc3.digitaloceanspaces.com
location_constraint = 
acl = 
server_side_encryption = 
storage_class = 
```

Once configured, you can create a new Space and begin copying files. For example:

```
rclone mkdir spaces:my-new-space
rclone copy /path/to/files spaces:my-new-space
```

### 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 [here](https://docs.minio.io/docs/minio-quickstart-guide).

When it configures itself Minio will print something like this

```
Endpoint:  http://192.168.1.106:9000  http://172.23.0.1:9000
AccessKey: USWUXHGYZQYFYFFIT3RE
SecretKey: MOJRH0mkL1IPauahWITSVvyDrQbEEIwljvmxdq03
Region:    us-east-1
SQS ARNs:  arn:minio:sqs:us-east-1:1:redis arn:minio:sqs:us-east-1:2:redis

Browser Access:
   http://192.168.1.106:9000  http://172.23.0.1:9000

Command-line Access: https://docs.minio.io/docs/minio-client-quickstart-guide
   $ mc config host add myminio http://192.168.1.106:9000 USWUXHGYZQYFYFFIT3RE MOJRH0mkL1IPauahWITSVvyDrQbEEIwljvmxdq03

Object API (Amazon S3 compatible):
   Go:         https://docs.minio.io/docs/golang-client-quickstart-guide
   Java:       https://docs.minio.io/docs/java-client-quickstart-guide
   Python:     https://docs.minio.io/docs/python-client-quickstart-guide
   JavaScript: https://docs.minio.io/docs/javascript-client-quickstart-guide
   .NET:       https://docs.minio.io/docs/dotnet-client-quickstart-guide

Drive Capacity: 26 GiB Free, 165 GiB Total
```

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> USWUXHGYZQYFYFFIT3RE
secret_access_key> MOJRH0mkL1IPauahWITSVvyDrQbEEIwljvmxdq03
region> us-east-1
endpoint> http://192.168.1.106:9000
location_constraint>
server_side_encryption>
```

Which makes the config file look like this

```
[minio]
env_auth = false
access_key_id = USWUXHGYZQYFYFFIT3RE
secret_access_key = MOJRH0mkL1IPauahWITSVvyDrQbEEIwljvmxdq03
region = us-east-1
endpoint = http://192.168.1.106:9000
location_constraint =
server_side_encryption =
```

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

```
rclone copy /path/to/files minio:bucket
```

### Wasabi ###

[Wasabi](https://wasabi.com) is a cloud-based object storage service for a
broad range of applications and use cases. Wasabi is designed for
individuals and organizations that require a high-performance,
reliable, and secure data storage infrastructure at minimal cost.

Wasabi provides an S3 interface which can be configured for use with
rclone like this.

```
