SpiderOak

I had high hopes due to price and encryption policy, but SpiderOak seems to be a mess. I tried to add under 2GB to my free 2GB account, and it estimated the files were actually 10GB. It uploaded flawlessly to Dropbox free 2GB account. With SpiderOak, I had to babysit it, uploading a few folders or files at a time so it wouldn't think I was going over my limit and ask me to purchase more space. If they don't know how to write a program that traverses a directory structure and does simple addition, then I don't really trust any of their technology.

Also, the Win7 GUI application is very slow - every time I switch to it it says "not responding" for a while.

SpiderOak not only backs up your files and synchronizes them from anywhere, seamlessly, but it is also a Zero-Knowledge application.

I love the peace of mind that comes from knowing that no one, not even the service owners, can access my remote files but me. Did I mention the "share rooms" for clients or family members? Overall, it just seems more sophisticated than I have come to expect.

Best of all, though, Zero-Knowledge products like spideroak and clipperz are slowly putting control of data on the cloud back where it belongs: with the user. Products like these help to lessen the ownership of our personal data by myriad different national corporations.

It still has some rough edges, according to other users. Though I have had no problems on my 3 linux machines, many report that though the restore process works it is still much less than seamless.

Still, I cast my lot with the Zero-Knowledge applications.

This has most of the features that Dropbox/Sugar Sync has with the exception of smartphone apps. The reason you would WANT this is total security. Dropbox has recently announced they own your data and can access it willingly(when they previously for years lied and said they couldnt).

Sugarsync has the same basic scheme for privacy and security.

SpiderOak's encryption is handled ON YOUR PC, your password is stored there as well, the spideroak staff cannot access your data based on this method giving you as complete privacy as possible.

Difference between TeamDrive, Dropbox and SugarSync

If you need a portable app similar to SpiderOak or the function of a FTP-server app, which you can run without admin rights you need TeamDrive (or DropBox without FTP-server function).

Advantages of TeamDrive:

• TD: Data are already encrypted before they are uploaded and the encryption key stays with you.

• TD+SS: You can synchronise existing folders and configure synchronisation specifically for individual folders (DropBox: only 1 folder).

• Only TD: You can set the access rights for each folder, too and you can run your own Teamdrive Personal server free up to 10GB (more comfortable than a FTP server) or use a WebDAV server.

• Free TeamDrive Online Storage 2GB + 250MB for each invited friend up to 8GB free.

• Portable versions from the developer existing for TD and DB , not for SS.

Disadvantages of TeamDrive

• Uninstalling-procedure of V 2.1.095 not OK: see http://is.gd/haLtrq .
• TD desktop windows version 2.1.095 could not manage the Proxy Server internet connection in a company network, in which there was a working proxy server connection with SS and DB with no problems. I did not test this bad behaviour with the new TD version 2.4.050 from Apr.2011.
