Ask HN: How do you encrypt then sync files to ANY cloud storage as offsite bckup?

2 points by goughgough ↗ HN
On a windows computer. But if you have a solution for Linux or Mac, I am happy to hear it.

I will pay money for it , as long as it works.

I need a solution to encrypt and then sync all my files to the cloud as offsite backup.

Here are my requirements:

    * Must have file versioning enabled in the cloud.

    * Must encrypt locally on my computer before being sent to the cloud.

    * Does not require me to create a virtual drive/folder on my hard drive and then drag and drop files to encrypt then back up. In other words, it encrypts current folders and files in my hard drive as I work on them. No drag and drop to a virtual drive/folder required.

    * Preferably open source.

    * Preferably no Java .

    * Preferably strongest encryption algorithm used --- Perhaps Truecrypt ? EncFS ? dm-crypt LUKS ?
To quote another person: "I'd love to see a fully open-source, zero knowledge, roll your own-solution, allowing it to be hosted on offsite VPS! I think this would pretty much solve the problem of cloud storage."

What would you recommend?

Thank you very much.

* TL:DR Please recommend a solution that can encrypt then sync to ANY cloud storage of my choosing , including Tencent or Kanbox (10TB free)

This is the OP expanding on my own question.

Right now, for your information , I am aware of these back up clients and the cloud they can sync to. Unfortunately, None of them can sync to any cloud storage of my choosing:

SyncBackPro Arq for Windows and Arq for Mac Syncovery Duplicati BitTorrent Sync Strongsync ExpanDrive CloudBerry CloudBacko Filement GoodSync Boxcryptor

I think it has something to do with the necessary use of the REST API from cloud storage. See this post.

Someone has asked me to check out git-annex .

Seems promising.

Will look it up down the track when I am much better at programming.

But in the mean time, I would be happy to find more for dummy solutions.

You will most likely have to compromise on a few of your requirements. Is there a reason you don't want to create a virtual drive?

I would suggest you use VeraCrypt (https://veracrypt.codeplex.com/), or the last full version of TrueCrypt (https://www.grc.com/misc/truecrypt/truecrypt.htm). Both are free and open source.

Encrypt your files locally then upload the encrypted file.

Thank you very much for your comments.

I have thousands of folders and files that I work on and I really don't want to drag every single one of them to a virtual drive on my computer after I am done with them.

The folders and files themselves are already sitting inside a virtual drive that was created with Truecrypt as I work locally on my computer.

I just don't want to create a Dropbox or Boxcryptor like virtual drive on my computer and drop and drag files into them before uploading.

I want those folders and files automatically encrypted and uploaded as I work on them.

You could write a program which automatically encrypts all the files in a specified directory and then uploads them every hour or so.

Thank you very much for this tip.

Here is my question .

If I am using Truecrypt now, how can I use Python (or any language) to create such program?

How do I go about using Google to find such tutorials?

Any advise would be very much appreciated.

Looking for all the help I can get.

Thank you very much.

JungleDisk (http://jungledisk.com) meets several your criteria and has Linux/Mac/Windows support, but its just too bad that since Rackspace bought them they've focused almost entirely on Rackspace's cloud storage offerings. It started with AWS support (and which I still use, but which is hard to buy from JungleDisk these days) and there originally were hints when they first added Rackspace support that they might continue to support arbitrary cloud storage backends and yet that never materialized. JD has nice sync engine and a good "shared source" deduped backup "vault" format. I just wish that JD would either Open Source their software or get back around to supporting more cloud backends. I get that Rackspace wants to focus on their own offerings, but I'd love to see the JungleDisk client get more capable, again.
