随着我们生活中越来越多的数据以数字格式存储，财务文档、家庭照片、工作项目的备份变得越来越重要。本周我们来看看你的备份策略。

本周早些时候，我们请您分享您的备份策略。成百上千的回复后，我们有了一个相当坚实的传播技术和技巧。

冗余是关键

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。如果没有冗余备份和离线/异地备份，那么就没有一个可靠的备份计划。对于大多数读者来说，冗余和离线驱动器是时下的事情。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.

理查德也表达了这种观点：

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 applicati*** 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.

Nancy将其与外部驱动器和服务器存储相结合：

1. I have a separate hard drive (WD MyBook) connected to my computer. I save all my data to this drive.

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.

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.

Redundant, but it works for me.

这个故事的寓意是，如果您的数据不在不同的位置，它就不会得到真正的备份。如果它对你很重要，它至少应该存在于三个地方，其中两个地方应该以某种形式离线（比如你放在消防保险箱里的外置驱动器或DVD）。

在线备份适用于小文件；有时很危险

基于云的存储在HTG读者群中不太受欢迎，原因有很多。那些对它感到满意的人通常只处理少量的文件，而只是将云存储作为备份方案中的另一层。Chrono写入：

Automatic synchronizing software and two sets of hard drives. Won’t save me from something like my house burning down, but it’s already saved me from a hard drive crash.

The really important stuff in in my Dropbox (encrypted with Trucrypt) where it gets copied to four different locati***.

他的安排相当普遍；超过四分之一的回复读者将Dropbox纳入了他们的备份计划。许多读者注意到，他们使用Dropbox处理小而重要的文件，而且大多数人在上传之前都对其进行了加密。

尽管不像Dropbox那样流行，但在备份大量数据时，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，但许多读者都有被它们烧掉并过渡到CrashPlan的故事。阿巴达巴写道：

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.

如果我们从不同的读者那里听到的关于云存储的危险的警告被提炼成一封简单的信，那就是：不要相信云是你唯一的冗余。

尽管许多读者对Carbonite和Mozy很满意，但值得注意的是CrashPlan有一些非常好的特性，包括本地备份（您可以使用该软件备份到网络上的其他机器）、远程备份（您和朋友/家人可以远程备份到彼此的机器），然后在CrashPlan的服务器上进行基于云的备份，所有服务器都使用相同的应用程序。
