2021年最好的云备份服务

底线：对于普通用户，iDrive提供了今天可以找到的功能，速度和价值的最佳融合。

iDrive备份详细信息：IDRIVE的个人备份计划每年的价格为69.50美元（如果您收到销售的话）并提供2TB的存储空间，那么对于大多数用户的个人文档和媒体来说，这将足够。IDRIVE应用程序易于安装，即使看起来有些过时，它也可以简单地使用。从表面上看，我很高兴地发现它很快上传了我的文件，并能够在应用程序中完全检索它们 - 它的主要竞争对手Backblaze无法宣称。恢复我的文件时，该应用程序提出将它们放回原始位置，或将它们转移到我选择的另一个位置。

iDriveoffers its users plenty of other perks. You can send the company a hard drive containing the files you want to upload and they'll copy them over directly, saving you hours or days of upload time. Flipping that around, they'll also send you a copy of all your files on a hard drive if your PC explodes, so you can quickly and easily copy them back. The service is even free if you send the hard drive back within a certain time frame. If you delete files from your local drive, iDrive will keep copies so you can restore them later if you have a change of heart. It also hangs on to old versions of your files, so if you have a change of heart you can undo changes even after you've saved.

Unlike some other cloud backup solutions, which require you to pay extra for each device you want to backup, iDrive also allows you to backup files from multiple computers and mobile devices to a single account. That’s great news for families.

底线：与iDrive相比，功能贫困，但是如果您有很多数据，则无法击败价值主张。

Backblaze备份详细信息：backblazeis one of just two cloud backup solutions I tested that offers unlimited storage, and it's the better of the two. Yep, you read that right: unlimited backups. So forget 2TB—if you have 50TB, that’s fine. 100TB? No sweat. A petabyte? Sure, in theory. The app is a breeze, too, with the easiest installation and simplest interface of all the services I considered. And at $5 per month, it’s bar-none the cheapest cloud backup solution around, especially when you consider that unlimited capacity. Better still, there are no file size or type storage limitations, so if you have a huge collection of 4K videos, FLAC audio, or RAW image files, it's a great pick.

但是，有很多怪癖使它无法成为我的首选。首先，默认情况下将所有个人文件备份，并且没有选择仅选择所需的文件。这种行为与我测试过的所有其他服务背道而驰，我认为这一点不方便。当我尝试仅备份一个文件夹（诚然，一个极端情况）时，这意味着我必须通过计算机的整个文件树并手动去选择其他一切.

Anyway, once your files are backed up, if you want to restore them you have to go through Backblaze's website. You can't use the beautiful desktop app. As is often (though not always) the case with cold storage, restores have to be "prepared," so you request the files you want, then wait for an email, and then download. Your files come in a ZIP archive, even when you only request one document, and there’s no option to restore files in place.

Finally, even though you have unlimited storage space to play with, Backblaze limits you to backing up a single device, and won't let you upload from network drives. Despite the stellar value proposition, these shortcomings kept it from taking our top spot.

Mozy已经存在云备份的场景了than most in this list, but it unfortunately hasn't kept up with the times. The company's app feels slow and the design is outdated. It's missing a lot of features, like network drive backups and continuous updates, and the pricing definitely doesn't help the situation. $72 a year gets you a mere 50GB of storage, and to get 125GB—still far less than you get with most competitors—you have to pony up $120. There's simply nothing here to justify that kind of spending.

像Mozy Home一样，ElephantDrive提供了非竞争性的定价和一个糟糕的应用程序，比您想象的要艰难。该应用程序无法正确缩放高分辨率监视器，并且导航非常不直觉。备份是一个痛苦的设置andto manage, because the app doesn't have a centralized interface. To change your backup settings, Windows users have to right-click the ElephantDrive icon in the system tray, then navigate to the settings sub-menu, which opens... wait, you're looking a little lost. Well, so was I—it’s even more confusing than it sounds. At $10 per month ($120 per year) for 1TB of storage, it's just not worth putting up with.
