试用每家云服务将会花费很多时间和工作。但是Reviews.com这家网站可能有帮助。这家网站调查了46家云服务，然后选择了4家满足其条件的云服务。
Why Use a Cloud Service
为何使用云服务
There are several reasons to use a Cloud service. One valuable feature is the protection of digital files, including photos, videos, documents, music and more.
使用云服务有多方面原因。一项最有价值的功能是保护数字文件，其中包括照片、视频、文档、音乐和其它文件。
If the worst happens and your computer crashes, or gets lost or damaged, your files can still be found in the Cloud.
如果遭遇极端情况，您的电脑系统崩溃了，或者是丢失或损坏了，您的文件仍然能在云上找到。
Access
可访问性
Cloud services let you access your files from almost anywhere. No need to worry about a file stored on your computer when you are away from your desk. If you have an Internet connection, you can open your files from any computer, or from a phone or tablet, when they are stored using a Cloud service.
云服务让您可以在任何地方访问您的文件。当您外出时，您无需担心文件保存在您的电脑上。当这些文件被保存在云服务上，只要您可以上网，您就能通过任何电脑或手机、平板电脑打开您的文件。
File Sharing
文件共享
Using a Cloud service makes sharing files easier. If you send documents to a group using email, you may then wonder which version everyone is working with. When sharing files using a Cloud service, everyone will see the same document and the latest version.
使用云服务让文件共享更为方便。如果您通过电子邮件向一群人发送文件，随后您可能想要知道每个人正在处理哪个版本的文件。当使用云服务共享文件时，每个人都能看到同样的文件以及最新的版本。
Transferring Files
文件传输
When switching computers, you will be able to transfer files easily if they are saved to a Cloud service.
如果文件储存在云上，当切换电脑时，您就能轻松地传输文件。
Choosing a Cloud Service
选择一家云服务
Which features should you consider when choosing a Cloud service? Some features may be important to you, while others will not matter as much.
当挑选云服务时，您应该考虑哪些功能？有些功能可能对您来说非常重要，而还有些功能不那么重要。
The first thing to consider is the amount of storage space you need. Consider that files such as photos, videos and music will take up more space than documents.
首先要考虑的是您所需的储存空间。要考虑到照片、视频和音乐等文件会比普通文件占用更大的空间。
Check how much space you are currently using on your computer and mobile devices. If your computer or phone is filled with photos and you have little free space, you may want to move your photos to the Cloud.
查看您目前在电脑和移动设备上使用了多少空间。如果您的电脑或手机装满了照片只剩下很少空间，您可能想要把照片转移到云上。
Some Cloud services are free. But, if you need a lot of space, you will probably need one that costs money.
有些云服务是免费的，但是如果您需要很多空间，您可能需要收费的云服务。
Works on Many Platforms
支持多平台
Even if everyone you have ever met is a Windows user, you still probably want a Cloud service that works with many platforms. No one knows what the future holds. You might become friends with an Android user or start a job with a company that computes on Apple! It could become important to have a Cloud service that works with many devices.
即使您看到的都是Windows用户，您可能仍然需要支持多平台的云服务。没人知道未来会怎样，您可能会与Android用户交朋友，或是到使用苹果电脑的公司工作。这时候一家支持多平台的云服务就会变得非常重要。
Cloud and Local Storage
云储存和本地储存
Some Cloud services back up your files to the Cloud and to your computer. Others back up only to the Cloud.
有些云服务将文件同时备份到云上以及本地电脑上。还有些云服务只备份到云上。
Using a Cloud service that backs up to both is probably best. This means you can have access to your files when you are on your computer but not linked to the Internet.
使用一家双重备份的云服务可能更好。这意味着当您电脑无法上网时也能访问您的文件。
What Others Are Using
其他人都在用哪家云服务
If your employer, partner or other important person in your life is using a Cloud service, you may want to use the same one.
如果您的雇主、合作伙伴或是您生活中的其他重要人士在使用云服务，您可能想要使用同一家。
Having More than One Cloud Service
使用多家云服务
But, if one is good, is more than one better? Consider carefully before signing up for multiple Cloud services. This can get confusing. Will you remember where you stored which files?
但是如果一家就行，多家是不是更好？在注册多家云服务前请仔细考虑。这可能会比较混乱。您能记得哪些文件储存到了哪家云服务了吗？
You may, however, want to use different Cloud services for work and for personal life to keep those files separate.
然而，您可能想要为工作和私人生活选用不同的云服务，好让这些文件分隔开。
