The choice of software for home backup via webdav: with versioning, encryption, multithreading, resume?

Question

Backup

Is there a similar software for home backup (on Windows)? Normal home PC, 10+ TB of data, need backups to the cloud.
Requirements in general typical:
1. Multithreading. There are rarely storages where 1 stream is able to give more than 10 Mbps. When there are 10, the total speed is acceptable.
2. Work on webdav and encryption. I don’t want to be tied to a specific service, I just chose which one I like and use. The quality deteriorated, something cheaper appeared - moved. Plus the encryption is locally on my side as a huge plus, no need to "trust" anyone. An example of such storage is the Hetzner Storage Box.
3. Resuming is required. Let's say you need to upload a 200GB file, the Internet has a low upload speed and often falls off. It should be possible when the connection is broken or the PC is turned off so that the download continues from the same place.
4. Versioning, incremental copies. Backups are performed daily, versions are needed for the last 30 days. We need the ability to get the state of the files "as was" for any of these 30 days. With the ability to do anything with them: select a specific file and restore, download everything, synchronize with the current local copy to see the differences and download only them.

Tested many solutions: Syncbackpro, Goodsync, Syncovery and a few dozen more. The combination of all points at the same time could not be found anywhere.
Advise, maybe there is already a similar software? Or are there any workarounds.

When the Internet is a couple of hundred Mbps or 1TB files, there are no difficulties at all. And if not? Interested in the whole experience of how to solve such problems.

Answer 1

I myself am also looking for similar software, so far nothing is better than bash scripts with a webdav mount, encryption compression and bla-bla, I did not find different disks - I did not find any sources. My answer can be done by hand, on commands, but it's possible so-so, I want a web interface.

Answer 2

Try Duplicati . Supports all popular clouds.
I do not advise you to become attached to WebDAV. It was not intended for backups. The native service API usually gives the best performance.
