Duplicati is a free, open-source backup software that can create and store encrypted backups online or on local disk drives. Duplicati supports Windows, Mac OS, and Linux.
It also uses a standard protocol like FTP, SSH, and WebDAV, as well as popular online storage solutions like Microsoft OneDrive, Amazon Cloud Drive, Google Drive, and many others.
Ubuntu comes with its backup software called Deja Dup. However, Duplicati supports more services than the default Ubuntu backup software. So if you’re looking for a simple-to-use backup solution for your Ubuntu desktop or server, you may find Duplicati useful.
Oh, one more thing Duplicati supports a web-based user interface for easy management.
This brief tutorial will show students and new users how to use Duplicati on Ubuntu systems to create encrypted backups.
