完善工作!

通常，当他们的驱动器发生故障时，人需要备份。 所有驱动器某时发生故障-没有从那真相的逃命。 但有保留好备份的其他原因：

• 总灾难，例如毁坏整体计算机和所有附近的备份的火或洪水。
• 故意淘气，例如删除重要文件的病毒。
• 一个或更多文件的偶然删除或修改。

我是肯定的有更多原因，但，如果我们盖这些我们大概把休息报道。

推进失败：

驱动器失败可能通过使用二反射镜传动主要避免在配置以RAID 1著名。 RAID意味重复一些独立驱动，并且有几个明确定义的水平。 RAID 1是一简单的comfiguration与确切地总包含同样信息的二驱动，因此“被反映的期限”。 如果任一驱动发生故障，其他简单地成为系统的单一驱动并且接管，不用栓。 因为二驱动的可能性立即出故障是非常小的， RAID 1相当很好盖子问题。 这里新的计算机使用RAID 1。

总灾难：

如果大厦烧…

英特尔E6750把CPU装箱，并且三个西部数字式320Gb SATA硬盘今天到达了，并且现在所有零件这里。 我设置了一切除了案件在野餐桌为相片。 在几张相片外面，我的糖果在背景中喜欢这一个以秋天颜色

然后我下载了在英特尔DP35DP主板展示如何安装处理器和“热量解答”的英特尔录影(风扇+吸热器)。 在一次演奏录影以后，我再玩了它并且做了设施，当观看录影时。 什么做棘手是十二个在许多微小的别针在主板插口在CPU薄酥饼必须与联络土地的一个相似的数字配比，没有弯曲任何别针。

And the CPU is just a wafer at this point, not fragile exactly but the motherboard pins are. You are supposed to set the square wafer straight down on the pins without sliding it at all, but I must admit that when I set it down it wasn’t perfectly aligned and it…

I’m struggling with the original precept of this blog: building a new computer, because my Gateway Performance 600 is working so well now. It’s almost eight years old, but it runs a Pentium III processor at 600 MHz and has been upgraded significantly:

1. Added another hard disk to increase total disk capacity from 20 Gb to about 100 Gb.
2. Replaced the original CD RW drive (failed) with a new and better Sony drive.
3. Upgraded from Windows 98 to Windows XP Professional, now SP2 and fully current.
4. Maxed out the memory to 768 Mbytes, comparable to brand-new low-end computers.

It’s not a bad computer, and I’m wavering on the decision to replace it. Money ($1000+) and time are the reasons NOT to replace it. Here are some reasons why I might:

• Quieter. The Performance 600, though not loud, is the loudest thing in the room.
• Faster. I wonder how much. The processors will be ten or twenty times as fast and the disk(s) at least twice

RAID is a computer acronym meaning “Redundant Array of Independent Disks.” Wikipedia. In this case we’re talking about “mirrored” disks, one of the simplest RAID configurations, where two identical disks contain identical data so that one can continue operating if the other fails. Since they contain the same data the second disk doesn’t add any disk capacity, but it does add reliability. Pros:

• The hard disk is MUCH less apt to crash. Only people who have experienced a crash can fully appreciate this.
• Perhaps I can get away with less backup, e.g. only back up the most sensitive data.
• Or, I can buy a THIRD drive and hot-swap it, so the swapped-out drive is the backup.
• I’d enjoy the experience of setting it up and using it.

Cons:

• It’s more expensive: I need two drives, not one, and the motherboard (which manages the drives) costs a little more.
• The drives will make twice as much noise. Hmmm.
• It doesn’t solve ALL backup problems: If I accidentally permanently delete a file, it will be gone on BOTH drives; if lightning hits the computer it could easily take out both drives.

I’m leaning toward…
