数据专员面试说什么

![2011-05-20\_115230][2011-05-20_115230]

With an increasing amount of our lives stored in digital format—financial documents, family photos, work projects—it is increasingly important to backup. This week we take a look at your backup strategies.

随着我们以数字格式(财务文件，家庭照片，工作项目)存储的生命越来越多，备份变得越来越重要。 本周，我们来看看您的备份策略。

Earlier this week we asked you to share your backup strategy. Hundreds of replies later we have a pretty solid spread of techniques and tricks.

本周早些时候，我们要求您分享备份策略。 数以百计的回复之后，我们掌握了相当多的技巧和窍门。

## 冗余是关键 **(**Redundancy Is Key**)** ##

We were pleased to see how many of you really had a lock on the core principles of backing up your data. If you don’t have redundant and offline/offsite backups then you don’t really have a solid backup plan in place. Redundancy and offline drives were the order of the day for most readers. Tony writes:

我们很高兴看到你们中有多少人真正掌握了备份数据的核心原则。 如果您没有冗余和脱机/异地备份，那么您实际上就没有可靠的备份计划。 对于大多数读者而言，冗余和脱机驱动器已成为日常工作。 托尼写道：

> Redundancy is key! At home, I don’t change enough to warrant frequent backups, but I have an external that I copy files to. I will save local and use the external along with a 2nd 1tb disk internal. In essence there is always 3 copies of a given file. Every time I rebuild or upgrade my OS (once a year or so), I also burn DVD’s of my data.

> 冗余是关键！ 在家里，我所做的更改不足以保证经常进行备份，但是我将文件复制到外部。 我将保存本地文件，并使用外部文件和内部第二个1TB磁盘。 本质上，给定文件始终有3个副本。 每次重建或升级操作系统时(大约一年一次)，我也会刻录数据的DVD。

Richard echoes this sentiment:

理查德对此情绪表示赞同：

> I am the King of Redundancy when it comes to backups. For the most part, I have multiple copies of backed up data (five copies at the minimum). Mostly done on a daily and/or weekly basis by automated synch programs. I have two drive image backups that are replaced every three months. Since I have the install disks for most all my applications and cloud based storage for the downloadable software I’ve purchased, the data is the more important. Most of it is irreplaceable, hence the redundancy. I use a lot of CDR & DVDR disks because of their cost effectiveness. For the image backups, I have them on their own dedicated 2-1/2″ USB External 500Gb drives.

> 在备份方面，我是冗余之王。 在大多数情况下，我具有备份数据的多个副本(最少五个副本)。 通常通过自动同步程序每天和/或每周完成一次。 我有两个驱动器映像备份，每三个月更换一次。 由于我拥有大多数应用程序的安装盘以及购买的可下载软件的基于云的存储，因此数据更为重要。 其中大多数是不可替代的，因此是冗余的。 我使用许多CDR和DVDR磁盘，因为它们具有成本效益。 对于图像备份，我将它们放在自己专用的2-1 / 2“ USB外置500Gb驱动器上。

Nancy mixes it up with a combination of external drives and server storage:

Nancy将其与外部驱动器和服务器存储组合在一起：

> 1. I have a separate hard drive (WD MyBook) connected to my computer. I save all my data to this drive.
> 
> 1.我有一个单独的硬盘驱动器(WD MyBook)连接到我的计算机。 我将所有数据保存到该驱动器。
> 
> 2. I use Windows Home Server to back up all four of my computers. The Server is built of mostly older parts; however, the motherboard, RAM and hard drives are all used for the first time in this machine.
> 
> 2.我使用Windows Home Server备份所有四台计算机。 服务器由大部分较旧的部件组成； 但是，本机首次使用了主板，RAM和硬盘驱动器。
> 
> 3. I have several (8 or 9 at last count) jump/flash/thumb drives. I keep particularly sensitive data on these, so it’s backed up three times.
> 
> 3.我有几个(最后计数为8或9个)跳跃/闪存/拇指驱动器。 我在这些数据上保留了特别敏感的数据，因此已备份了三遍。
> 
> Redundant, but it works for me.

> 多余，但对我有用。

The moral of the story is that if your data isn’t in separate locations it’s not truly backed up. If it’s important to you, it should exist in at least three places and two of those places should be offline in some form (like an external drive or DVD set that you keep in a fire safe).

这个故事的寓意是，如果您的数据不在单独的位置，则不会真正进行备份。 如果对您来说很重要，则它应该至少存在于三个位置，并且其中两个位置应以某种形式脱机(例如，保持防火的外部驱动器或DVD机)。

Cloud based storage wasn’t very popular among the HTG readership for a variety of reasons. Those who were happy with it generally were working with small amounts of files and were just using the cloud storage as yet another layer in their backup scheme. Chronno writes:

由于各种原因，基于云的存储在HTG读者群中并不是很流行。 对此感到满意的人通常只处理少量文件，而只是将云存储用作备份方案的另一层。 Chronno写道：

His arrangement was a fairly common one; more than a quarter of the responding readers incorporated Dropbox into their backup plan. Many readers noted that they used Dropbox for small but important files and most of them encrypted it before uploading.

他的安排很普通。 超过四分之一的回应读者将Dropbox纳入了他们的备份计划。 许多读者指出，他们将Dropbox用于较小但很重要的文件，并且大多数人在上传之前对其进行了加密。

Although not as popular as Dropbox, when it came to backing up larger volumes of data many readers turned to services like Carbonite, CrashPlan, and Mozy. Although Carbonite and Mozy are widely popular online backup solutions, many readers had stories of being burned by them and transitioning to CrashPlan. AbbaDabba writes:

尽管不如Dropbox受欢迎，但是当涉及到备份大量数据时，许多读者转向了Carbonite，CrashPlan和Mozy等服务。 尽管Carbonite和Mozy是广泛流行的在线备份解决方案，但许多读者还是有被其烧毁并过渡到CrashPlan的故事。 AbbaDabba写道：

> I back up all computers to a Windows Home Server machine. I then use a cloud service called CrashPlan. They’re cost effective and very reliable. I used to use Carbonite but they lost lots of my data because of a major bug in the program.
> 
> 我将所有计算机备份到Windows Home Server计算机上。 然后，我使用名为CrashPlan的云服务。 它们具有成本效益并且非常可靠。 我曾经使用Carbonite，但是由于程序中的一个重大错误，他们丢失了很多数据。

If the warnings we heard from various readers about the danger of cloud based storage are distilled down into a simple missive, it’s this: don’t trust the cloud as your only redundancy.

如果我们从各种读者那里听到的有关基于云的存储的危险的警告被简化为一个简单的误报，那就是：不要相信云是您唯一的冗余。

While many readers were happy with Carbonite and Mozy, it’s worth noting that CrashPlan has some pretty sweet features including local backup (you can use the software to backup to other machines on your network), remote backup (you and a friend/family member can remotely back up to each other’s machines), and then cloud-based backup on CrashPlan’s servers—all using the same application.

虽然许多读者对Carbonite和Mozy感到满意，但值得注意的是CrashPlan具有一些非常不错的功能，包括本地备份(您可以使用该软件备份到网络上的其他计算机)，远程备份(您和朋友/家人可以远程备份到彼此的计算机)，然后在CrashPlan的服务器上进行基于云的备份-全部使用同一应用程序。
