About rclone
rclone is a command line tool allowing data transfer from and to cloud storage providers, described as 'rsync for the cloud'. This guide will show you how to use it to transfer data to Amazon S3 Glacier.
Requirements
You need an AWS account to utilize cloud storage. At this time, these accounts are not provided by the SCU.
Warning |
---|
Be advised that using AWS will incur costs separate from any existing agreement with the SCU, or other WCM groups. Use the Amazon Cost Explorer to estimate the costs for this service. |
Once you have an AWS account, you need to create an IAM user with the permissions to use S3 and Glacier. Please refer to the amazon documentation on how to do that.
Rclone is available on the SCU nodes. The following example is on pascal.med.cornell.edu.
The easiest way to configure Rclone is via rclone config
, which opens an interactive tool. The following is an abbreviated log of the settings for AWS:

Remote config
--------------------
[amazon_store]
type = s3
provider = AWS
env_auth = false
access_key_id = [REDACTED]
secret_access_key = [REDACTED]
region = us-east-1
acl = private
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
Current remotes:

Once this configuration is saved, you are ready to use rclone.
Info |
---|
Note that this example uses standard S3 storage, which is relatively expensive. Within the configuration, you can select a less expensive storage class such as Infrequent Access or Glacier . Learn more about Object Storage Classes. |
To transfer data to the new remote (named amazon_store
in the example above), use this syntax:
Code Block |
---|
|
$ rclone copy -P ~/test_data amazon_store:rclone-tutorial
Transferred: 192M / 192 MBytes, 100%, 24.736 MBytes/s, ETA 0s
Errors: 0
Checks: 0 / 0, -
Transferred: 2 / 2, 100%
Elapsed time: 7.7s
$ |
Note that the -P
flag gives you the progress indicator.
To download data from the cloud, use this:
Code Block |
---|
|
$ rclone copy -P amazon_store:rclone-tutorial ~/test-download
Transferred: 192M / 192 MBytes, 100%, 77.531 MBytes/s, ETA 0s
Errors: 0
Checks: 0 / 0, -
Transferred: 2 / 2, 100%
Elapsed time: 2.4s
$ ls ~/test-download/
test1.file test2.file |
rclone browser - Graphical user interface
If you want to run rclone on a desktop, you can use rclone browser for a graphical user interface to your remotes. For this to work, you need to have the rclone binaries installed on your local machine as well. Refer to the respective sites for documentation on how to install and configure this.
Please note: This is not suitable to move large amounts of data. Only use this for smaller amounts of data, or for managing inventory.
