I am blown away by this. Very simple and elegant. Nice Job. What tech stack is this application built in?
Thanks!
Its built in a combination of C and python. Using zstandard for compression and openssl for crypto. Qt for the GUI.
Show HN: Minimalist App for Backups to Any Storage

Re: Show HN: Minimalist App for Backups to Any Storage
#12The one thing that finally works for me for backup is restic ( https://restic.net/ ). I use linux and set my home dir to a different partition, Run a daily script that uses restic to backup to backblaze. Smooth as butter and hopefully I don't need to use it. Curious what this uses under the hood, wouldn't be surprised if it was restic.
It uses a custom algorithm and data format but uses a similar deduplication technique to restic. There is bit of info in the docs page about this [1].

#13Nice work! If one were to buy this and want to back everything up from local device(s) and cloud accounts back down to a local NAS - supported use case?
Ah this isn't supported right now. It wouldn't be terribly difficult to add but it's just never been brought up by users till now. What is your use case for this?
Or maybe I'm confused about your question haha.
Do you simply mean is it possible to restore backups to local? Or a reverse backup operation from cloud to local?

Obviously this is needed to make block level deduplication possible, but it also means that for this "end to end encrypted" product someone can still tell whether or not you own a given file. This is probably fine for most people but worth calling out.

#15We (rsync.net) will test this out immediately - we're always happy to see tools like this that support plain old SFTP.
If, for any reason, you'd like a free test account, just email info@rsync.net.
Thank you for building this!

Good catch. But the SHA hash is salted per backup destination though. So you can't figure out the content from the hash alone.
EDIT: I should make note of that on the docs page really. It currently gives the impression that I'm just straight up calculating the sha of the content.

#17On Windows does it use VSS to snapshot the volume and backup open (locked) files?

#18Aesthetics-wise this looks very heavily "inspired" by https://bvckup2.com.
The UI is basically a 1-to-1 copy of an older version:

"Good artists create, great artists copy", but that's a bit too close for comfort.

IMO that UI is simple and generic enough that it wouldn't be impossible for them to have come to it independently.

Restic is great indeed. Takes some time to get started, I appreciate that encryption comes first.
