The first time you open the app, you won't even see an application screen. Instead, you're popped into a Google permissions screen online, an indication of how closely Insync is tied with Google. Once you initiate a sync, all of the Google Docs crap you've ever opened will get downloaded to your computer. One cool feature is that unlike Drive, Insync will automatically convert your files into formats (like .doc) that you can read on your computer. Drive syncs Docs to your computer as web shortcuts. In fact, you might want to use Insync solely as a file manager for your Google Docs files since it lets you drag-and-drop things around between folders (labels in Google Docs). Move files within these folders and the next time you check Google Docs, the file will have switched labels. In the end, Insync is a great solution for syncing files to and from your Google Docs account, but doesn't let you sync much else. Also, the company's mobile apps are in private beta, which means you can't use them just yet. Pricing: 25GB for $2.49/month; 100GB for $4.99/month; 200GB for $9.99/month; more options from Google.
Wuala: store data online, and share them if you want
Another problem is defining who, and under which circumstances, can gain legal permission to access data stored on the cloud. Users believe that their information isconfidential and protected from everyone just because it belongs to them and is their property. But they often forget that the space where they store it (namely the Internet) is not actually theirs and it functions by its own rules (or no rules). Therefore, you may still have to give up your data if one day state authorities ask for it.
In the world we live in, having unencrypted data is not considered very secure, as unencrypted data can be easily viewed and tampered with. Whenever we want to share some data with a friend or only transfer the data from one computer to the other, our data can be viewed in transit. Since there are multiple ways of transferring the data from one system to the other, there must also be different techniques that attackers use to view and modify the data.
When reviewing data security, many people underrate the need for availability. However, not being able to access data when you need it, or data loss, is probably the largest data security risk in a cloud file sync and share service. It is critically important that a cloud storage service maintains backups, stores version information, has highly available data stored across multiple locations, and that there is a way to recover data if a user forgets their password.
Even though file synchronization seems to have been an afterthought, the company has done a good job with its synchronization software. Users are required to use the Secure Sync software to back up any data they want to synchronize. Once backed up, the data can be synchronized between PCs or between a PC and an external storage device. SpiderOak offers versions of its software for Windows, Linux and Mac OS X, so it's possible to share and synchronize files across platforms.
What I like about ZumoDrive is that it integrates seamlessly into Windows. Figure 4) shows ZumoDrive has mounted as a network drive. This means you can use the data on the shared drive as if it were stored locally.
IIUC the data is stored in a plain Git repo (or are there any Sparkleshare specific extensions?); so while the client software might be problematic, the data is in an open format. If you suddenly have to pay fees for using Mono, you can still extract your files with command-line git, or by writing a Sparkleshare replacement in your favorite language.
However, 99% of online vendors will have the capability to read my data. So I become choosy and not trust everyone. I trust only GMail and Wuala (because there is no cheaper alternative for such a huge high-available mailing system) The reason why I trust wuala is no one apart from me can read the data that I store with them. The way in which they get money is by paid accounts. I like this model (much like flickr). 076b4e4f54
