Apps to sync multi cloud and backup

TIL the concept of syncing multi cloud and backup directly into cloud storage.

I already wrote a note related to some apps to sync multi cloud. This note is an expansion of the previous one.

Rclone

Rclone is a command-line program to manage files on cloud storage

It is mature, open-source software originally inspired by rsync and written in Go
Features:
- Backup (and encrypt) / Restore (and decrypt) files to/from cloud storage
- Mirror cloud data to other cloud services or locally
- Migrate data to the cloud, or between cloud storage vendors
- Mount multiple, encrypted cloud storage as a disk
List of supported cloud providers

Kopia is a a fast and secure open-source backup/restore tool for Windows, Mac, and Linux.

Kopia has both CLI (command-line interface) and GUI (graphical user interface) versions 1
Kopia allows you to create encrypted snapshots of your data and save the snapshots to remote or cloud storage of your choice, to network-attached storage or server, or locally on your machine.
Kopia does not ‘image’ your whole machine. Rather, Kopia allows you to backup/restore any and all files/directories that you deem are important or critical.
