Java API - 云服务
我希望很多人已经了解 Dropbox 云服务，用于在不同客户端之间存储和同步文件。我毫不犹豫地使用第三方服务来存储我的个人文件。
我正在尝试使用我的 2TB 硬盘构建个人云存储。我想我正在寻找关于从哪里开始、使用哪些 API [最好是 JAVA 和 J2EE]、安全性、风险的指导？
I hope many people already know about the Dropbox Cloud Service for storing and syncing files across various clients. I am little hesitant using a third party service to store my personal files.
I am trying to build a personal cloud storage using my 2TB Hard Drive. I guess I am looking for pointers on where to start, which APIs to use [preferably JAVA and J2EE], security, risks?

首先，我强烈建议你克服偏执狂； Dropbox 员工在午餐时间查看您的照片或其他内容的可能性微乎其微。事实上，数百万人将他们的资料存储在 Dropbox 上，没有人的隐私受到侵犯。
也就是说，Dropbox 基于 Amazon S3，它（因为我假设您信任 Amazon 就像您信任 Dropbox 一样）有一个您可以自己运行的开源克隆。看看桉树。由于您专门提到了 Java，我会指出，优秀的 AWS SDK for Java 也能正常工作在 Eucalyptus 的 S3 商店中与在 Amazon 上一样。
First, I would highly recommend getting over your paranoia; chances are extremely slim that Dropbox employees are going to spend their lunch hour looking at your photos or whatever. Literally millions of people store their stuff on Dropbox and nobody's had their privacy violated.
That said, Dropbox is based on Amazon S3, which (since I assume you trust Amazon just as much as you trust Dropbox) has an open source clone that you can run yourself. Take a look at Eucalyptus. Since you specifically brought up Java, I'll point out that the excellent AWS SDK for Java works just as well on Eucalyptus' S3 stores as on Amazon's.
如果你的 2TB 硬盘上有云存储，那它怎么样？为什么您认为通过互联网访问您自己的服务会比专门从事此服务的人员运行的服务更安全。我想亚马逊在 HTTP 可访问文件存储 (S3) 方面可能比其他任何人都拥有更多的经验。
如果您想确保没有人可以查看您的资料，我建议您在将其保存到 S3 之前考虑对其进行加密。这将使客户端访问变得更加困难，因为您始终需要正确的工具来执行加密操作，但这就是您必须付出的代价。
How is it Cloud storage if it's on your 2TB hard drive? Why do you think your own service will be more secure when accessible through the internet then a service run by people who specialized in doing it. I guess Amazon has probably more experience than anybody else in terms of HTTP accessible file storage (S3).
If you want to make sure nobody can look at your stuff I suggest you look into encrypting it before saving it into S3. That would make it harder to access on the client side, because you always need the right tools to do the encryption stuff but that is the price you'd have to pay.
