RAID Backup空袭备份
Working perfectly!工作完美！
Usually, a person needs a backup when their disk drive fails.通常，一个人需要有一个备份，当他们的磁盘驱动器失败。 All disk drives fail sometime - there is no escape from that truth.所有磁盘驱动器失败的某个时候-没有脱离这个真理。 But there are other reasons for keeping good backups:但除此以外，还有其他的原因，保持良好的备份：
- Total disaster, such as a fire or flood that destroys the whole computer and all nearby backups.总的灾害，如火灾或洪水破坏整个计算机和所有附近的备份。
- Deliberate mischief, such as a virus that deletes important files.故意恶作剧，如病毒，删除重要文件。
- Accidental deletion or modification of one or more files.意外删除或修改的一个或多个文件。
I’m sure there are more reasons, but if we cover these we’ll probably have the rest covered.我敢肯定，有更多的理由，但如果我们包括这些，我们将可能有其余的包括在内。
Drive Failure: 驱动器故障：
Disk drive failure can mostly be avoided by using two mirrored drives in a configuration known as RAID 1.磁盘驱动器故障，可以大部分避免使用两个镜像驱动器的配置称为RAID 1 。 RAID means Redundant Array of Independent Drives, and has several well-defined levels.空袭的手段冗余阵列独立的驱动器，并有几个清楚界定的水平。 RAID 1 is a simple comfiguration with two drives which always contain exactly the same information, hence the term “mirrored.” If either drive fails, the other simply becomes the system’s sole drive and takes over without a hitch. RAID 1的是一个简单的comfiguration与两个驱动器，其中总是包含资料完全相同，因此，长远的“镜像” ，如果不是驱动器出故障，其他只是成为该系统的唯一驱动器和接管没有顺利。 Since the probability of two drives failing at once is very small, RAID 1 pretty well covers that problem.由于概率两个驱动器未能在一次非常小， RAID 1的相当不错，包括这个问题。 The new computer here employs RAID 1.新电脑在这里雇用的RAID 1 。
Total Disaster: 总灾害：
If the building burns…如果建设的烧伤…
