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 is used at the command line, in scripts, or via its API. Rclone really looks after your data. It preserves timestamps and verifies checksums at all times. Transfers over limited bandwidth; intermittent connections, or subject to quota can be restarted, from the last good file transferred. You can check the integrity of your files. Where possible, rclone employs server-side transfers to minimize local bandwidth use and transfers from one provider to another without using the local disk.

yCopy2 is a backup/sync tool with multi-threading and a rich set of command-line variables. Warning: the SYNC option will recursively delete files & folders from the destination path which aren't present on the source. Use with caution, and experiment with unimportant files first. I've been using yCopy2 to back up my stuff for a couple of years now, but that doesn't mean the program will suit your needs. Use this software at your own risk. Due to a limitation in Microsoft .Net, yCopy cannot back up files where the source or destination path + filename is longer than 256 characters. E.g. C:\Temp\etc\etc\more stuff\(to a depth of 256 chars)\Some really long file name.doc. A network mode where yCopy2 will communicate in a client-server fashion, speeding up lan backups. Built-in scheduling to run backups at specified intervals. Compatible with Windows 7 SP1 and newer.
