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 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.

A discussion in Hacker News.


Duplicati is a free backup software to store encrypted backups online.

This app was discussed in Hacker News. They don't recommend to use Duplicati. 2
