SpiderOak

This program has real promise. Similar to Mozy, with cross-platform clients (Mac, Windows, Linux), you get 2 GB free and 100 GB for $$$. It has the unique feature of having "zero knowledge encryption", which means your files are encrypted at the client with YOUR KEY, stored encrypted on the server, and not even the names of the files can be determined by SpiderOak or anyone else. This is true security. In addition to the OS client, there is web-based access where you can download a file, and a neat sharing facility that allows you to share some or all of your files with others. In my testing I've found the program very fast to upload, with good block-level hashing to upload only the "changed" portion of your files (great for those big files, especially your Entourage database). There are still things to fix, and the Mac interface isn't too Mac-like (as noted by other reviewers), but the developers are very responsive and interested in making things better.

SpiderOak cans its Warrant Canary, suffers mysterious massive outage, and raised prices: https://www.reddit.com/r/privacy/comments/94nspi/spideroak_cans_its_warrant_canary_suffers/

The current version is 6.3.0

the real outstanding feature of spideroak is that you can backup and sync any folder on your system. i didnt find any cloud service where this was possible. (if anybody knows another app for this plz respond)

Spideroak is the Cloud Service I want to use, because privacy is their number one priority. They really do care about keeping everything as save as possible and came up with the idea of Zero Knowledge as the gold standard. It means that Spideroak as a company does not have any access to your master password. That way if the NSA comes sniffing around, there's simply nothing to give them. In the role of a super paranoid user thats the best you can get, except for one more thing: Spideroak is a US company with servers also located in the US. In paranoid theory that means that the US goverment can make Spideroak implement a backdoor into the software. Something that they kinda worked around with their canary feature. But still, one thing i dislike about Spideroak is the fact that they did everything to keep your data as save as possible, except for the fact that its a US based company, which puts them under quite a lot bullshit privacy laws the USA have. You might argue that this is extremely paranoid and i completely agree with you, but i personally beleive that spideroak only makes sense to use if you are extremely paranoid.

Another thing i like about Spideroak is the fact that they offer Cloud BackUp (like Crashplan or Backblaze) and Cloud Syncing (like Dropbox and Google Drive) at the same time. So you dont need two services anymore, but just one super secure service, which is great!

But because of its extreme security comes the downside that it limits you in many ways. With the Spideroak mobile app you can pretty much only look at files. There is no mobile upload for adding files or uploading all your pictures, theres no simple(!) sharing like you know from Dropbox and others. Sure its great to store all your files in a super secure vault, but for documents you access and modify daily, its a pain in the a** having to open the vault everytime.

The speed of Spideroak isn't very good. I havent done any real speedtest i could display, but it just doesnt feel fast. There are many reviews of Spideroak saying the same thing. Its just not a fast service. And that can be really annoying if you have to download a huge backup.

The App SpideroakONE finally looks better than the old verion from the 90s. Sadly it seems to be the same application underneath which needs a lot processing power and makes my computer feel slow from time to time. However its a very powerful app with lots of settings.

SUMMARY: Spideroak does its best on keeping your files private and save, but being a US service is a huge bummer, because like it or not the USA is spying more today than probably all other countries combined. So if you want to go the extra mile behind the first extra mile, id choose a european service to begin with, where the government is much more limited on what theyre allowed to access. Plus the super privacy on Spideroak limits you in so many ways. When using Spideroak youll see yourself using the cloud much less, because there arent all the features youre looking for compared to Dropbox or Drive. Its just super annoying.

Recommendation: Decide on how much time, efforts and lack of features youre willing to accept for a certain level of security and privacy. I have all my files on OneDrive which isnt nearly as encrypted as Spideroak. Thats why I keep a seperate folder for important Stuff encrypted inside my OneDrive. The security now is comparable to Spideroak. The Master Password is only on my local computer and the encrypted files are stored inside the US. That way i get all the goodies from a cloud service for regular files. important files are encrypted and to be accessed with a little workaround. For backup i connect Arq to my OneDrive which also encrypts all my backups and stores them safely. OneDrive is not only one of the cheapest today for $50 a year, it also give you unlimited cloud storage and also includes Microsoft Office 365, which many of us need anyway. Plus the performance of OneDrive is surprisingly good.

To me theres just no reason on using Spideroak and i imagine there to be only a very tiny group of people actually benefitting from it.

After downloading and installing, it slowed down my Mac so I had to uninstall it. I don't know why they don't test these app out before the release them.

To enlighten my former review, here is the mail I had by the end of March from SpiderOak support: "Unfortunately, you won't be able to run the newest version of SpiderOak if you are still using OS X 10.6 or older versions. Beginning with version 5.1.10, SpiderOak requires OS X 10.7 Lion or higher. If you are still running on OS X 10.6 Snow Leopard, you will need to upgrade in order to use SpiderOak. As a temporary workaround, you may use an older version of SpiderOak which works on OS X 10.6. You can get it at no cost here: https://spideroak.com/getbuild?platform=mac&version=5.1.8 Please note, however, that our new version 5.1.10 introduces an important security improvement. In order for SpiderOak to always be proactive in using the latest security and privacy standards, we are moving to SHA-256 based SSL certificates, and versions prior to 5.1.10 are not compatible with them. When the move is complete, older versions of SpiderOak will no longer connect to our servers. This will happen soon, so act now to avoid any service interruption."

I'm Loving It!!!
