Duplicati
Duplicati Inc. and community
Duplicati backs up selected folders on a schedule, encrypts the data on your own machine with AES-256 before it leaves, and sends only the blocks that changed. Destinations include Amazon S3, Backblaze, Google Cloud, OneDrive, Dropbox, Azure, SFTP, FTP, WebDAV, a NAS and local disks. It suits an engineer who wants an encrypted copy of the projects folder in cloud storage they already pay for, with a version-retention policy. Setup and restore are done in a local browser interface. Limitation: full-disk backup and Microsoft 365 backup are proprietary modules that need a licence for production use.
