Original short description: "Cloud storage management software"

Software

Rclone is an open source, command line computer program to manage files on cloud storage. Its capabilities include sync, transfer, encrypt, cache, union and mount. The rclone website lists fifty supported backends including S3 services and consumer file sharing platforms.[1]

Descriptions of rclone often carry the strapline Rclone syncs your files to cloud storage.[1] Those prior to 2020 include the alternative Rsync for Cloud Storage.[2] Users have called rclone The Swiss Army Knife of cloud storage,[3] and likened it to magic.[4]

Whilst rclone is well known for its rlone sync and rclone mount commands,[5] it provides further file management functions analogous to those ordinarily used for local disks.

Rclone is widely used at hpc research sites to transfer large datasets. Examples include the University of Maryland,[6] Iowa State University,[7] University of Utah,[8] National Institutes of Health,[9] Wharton,[10] Yale,[11] Minnesota,[12] Michigan State,[13] and Berkeley.[14]

Official Ubuntu, Debian, Fedora, Brew, Chocolatey, and other package managers include rclone.[15]

History

Nick Craig-Wood was inspired by rsync.[2] His wife's concerns about the noise and power costs arising from their home computer servers prompted him to move to cloud storage and begin developing rclone[16] in 2012.[17]

Rclone was promoted to stable version 1.00 in July 2014.[17]

In May 2017 Amazon barred new rclone users from its consumer Amazon Drive data storage product. Amazon Drive had been advertised as offering unlimited storage for £55 per year. Amazon blamed security concerns and also banned other upload utilities.[18] Amazon's more expensive AWS S3 service continues to support new rclone users.

The original rclone logo was retired to be replaced with the present one in September 2018.[19]

Amazon's AWS April 2020 public sector blog explained how the Fred Hutch Cancer Research Center were using rclone in their Motuz tool to migrate very large biomedical research datasets in and out of AWS S3 object stores.[20]

May 2020 reports stated rclone had been used by hackers that attacked Diebold Nixdorf ATMs.[21][22]

Backends and Commands

The following services are supported as rclone backends. There are others, built on standard protocols such as WebDAV or S3, that work.[1]

1Fichier | Alibaba (Aliyun) Object Storage System (OSS) | Amazon Drive (See note) | Amazon S3 | Backblaze B2 | Box | Ceph | Citrix ShareFile | C14 | DigitalOcean Spaces | Dreamhost | Dropbox | FTP | Google Cloud Storage | Google Drive | Google Photos | HTTP | Hubic | Jottacloud | IBM COS S3 | Koofr | Mail.ru Cloud | Memset Memstore | Mega | Microsoft Azure Blob Storage | Microsoft OneDrive | Minio | Nextcloud | OVH | OpenDrive | OpenStack Swift | Oracle Cloud Storage | ownCloud | pCloud | premiumize.me | put.io | QingStor | Rackspace Cloud Files | rsync.net | Scaleway | Seafile | SFTP | StackPath | SugarSync | Tardigrade | Wasabi | WebDAV | Yandex Disk

One, or more, remotes are usually defined from these backends, local disk, or memory (as S3), with rclone config. Rclone can further wrap those remotes with one or more of alias, encrypt, chunk, cache, or union remotes.

Once defined, the remotes are referenced by other rclone commands interchangeably with the local drive. Remote names are followed by a colon to distinguish them from local drives. For example, a remote example_remote containing a folder, or pseudofolder, myfolder is referred to within a command as a path example_remote:/myfolder.[23] Many rclone commands refer to paths, not files. [24]

Rclone commands directly address remotes, or mount them, for other programs (with cache options), as if a conventional disk. They serve remotes over SFTP, HTTP, WebDAV, FTP and DLNA.[1] Commands can have sub-commands and a range of modifier flags.

Academic evaluation

In 2018, University of Kentucky researchers published a conference paper comparing use of rclone and other command line, cloud data transfer agents for big data.[26] The paper was published as a result of funding by the National Science Foundation.[27]

In 2018, the University of Utah Center for High Performance Computing examined the impact of rclone options on data transfer rates.[28]

Future

Rclone can serve a beta, web based remote control, graphical interface - rclone rc[29].

An rclone compression backend is under development to address small file, and compressible file format, transfer capacity.[30]

There have been persistent calls for a --magic flag to improve rclone.[31][32][33][34][35]

Rclone and rsync

Rsync transfers files between computers it is installed on. Rsync operates at the block level and has a delta algorithm so that it only needs to transfer changes in files. Rclone has a wider range of file management capabilities, and types of backend it can address, but only works at a whole file/object level.[36] Rclone decides which of those whole files to transfer after obtaining checksums, to compare, from the remote server. Where checksums are not available, rclone can use file size and timestamp.[37]

Eponymous cloud storage service rsync.net provides remote unix filesystems so that customers can run rsync and other standard unix tools.[38] They also offer rclone only accounts.[39]
