What are the advantages compared to say, Rclone which is open-source and supports a wide variety of storage backends[1] and E2E encryption[2] as well?

1. Compression/deduplication. Your data will (generally speaking) take up about half the space it did before even including the multiple file versions.
2. Automation. You won't have to manually do anything after you configure a schedule once.
3. Management of multiple backups.
4. A really nice native GUI
5. All the advantages that backup with file versioning has over sync (which is what it looks like you have). Safe from ransomware (you'll have an older version always even if your infected ones get synced accidentally), projection from human error by being able to revert to older versions, etc

Which version of Duplicati was used in this benchmark?
The largest backup a user has reported using this with has been 5 tb and it ran without a hitch.
I'm pretty sure it was the latest duplicati for the benchmark. Maybe the second latest. I forget.
