In the latest version of Nephele, you can now create a WebDAV server that deduplicates files that you add to it.
I created this feature because every night at midnight, my Minecraft world that my friends and I play on gets backed up. Our world has grown to about 5 GB, but every night, the same files get backed up over and over. It's a waste of space to store the same files again and again, but I want the ability to roll back our world to any day in the past.
So with this new feature of Nephele, I can upload the Minecraft backup and only the files that have changed will take up additional space. It's like having infinite incremental backups that never need a full backup after the first time, and can be accessed instantly.
Nephele will only delete a file from the file storage once all copies that share the same file contents have been deleted, so unlike with most incremental backup solutions, you can delete previous backups easily and regain space.
Edit: So, I think my post is causing some confusion. I should make it clear that my use case is specific for me. This is a general purpose deduplicating file server. It will take any files you give it and deduplicate them in its storage. It's not a backup system, and it's not a versioning system. My use case is only one of many you can use a deduplicating file server for.
Actually you seem to have reinvented Syncthing's versioning feature... or this.
Still great work.
So, to be clear, this is not a versioning system. I'm just kind of using it for that with my Minecraft backups. This is a deduplicating file server. It takes the files you give it and deduplicates them. Then, later, you can pull them out again. I am using it for backups, but it is also not a backup system.
I think I made it seem in my post like what I’m using it for is what it should be used for, or the only thing it can be used for. My use case is just one of many that you can use a deduplicating file server for.
