Rclone v1.52.0 released 2020-05-27 (changelog at
https://rclone.org/changelog/).
Since posted here back in 2016 a lot has changed, not least the amount of compatible file hosts -- here's the full list as copied
verbatim from the ReadMe file (highlights are mine):
1Fichier, Alibaba Cloud (Aliyun) Object Storage System (OSS), Amazon Drive, 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, Memory, 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, and the local filesystem.
The main
rclone highlight has to be its builtin functionality to encrypt cloud storage; for a brief intro, check
https://rclone.org/crypt/. But, alas, as I
noted above there's no delta sync.
Rclone is a command line program to manage files on cloud storage. It is a feature rich alternative to cloud vendors' web storage interfaces. Over 40 cloud storage products support rclone including S3 object stores, business & consumer file storage services, as well as standard transfer protocols.
Rclone has powerful cloud equivalents to the unix commands rsync, cp, mv, mount, ls, ncdu, tree, rm, and cat. Rclone's familiar syntax includes shell pipeline support, and '--dry-run' protection. It can be used at the command line, in scripts or via its API.
Rclone also sports an experimental web-based GUI by default -- for more info, check
https://rclone.org/gui/.
FYI, there's also independently developed
RcloneBrowser (
https://github.com/kapitainsky/RcloneBrowser) with
native portability (just create an INI file with same name as the EXE alongside, otherwise settings will go to registry and '
%APPDATA%').
Rclone 32 and 64-bit Windows versions can be downloaded from
https://rclone.org/downloads/ (releases repo is at
https://downloads.rclone.org/).
