synology默认设的raid1
这样磁盘空间小了一半
如果这样可以有个额外的备份也好
但是老有人说raid不是备份
只是为了提高可用性
raid恢复不出来的情况也很多
那要怎么设定好?
nas里面是两块3T的日立盘
我还有两块2T wd 外置盘
其中一块常年挂在路由上,不知道是不是要挂了
另一块usps当年给我邮不见了,我去投诉才拿回来,基本没敢用,不知道是不是也要挂了
我希望我的几台电脑都能backup到nas,还有个人文件,照片
这些我希望备份到nas之后还有一个冗余备份
另外一些东西,歌曲视频啥的,nas就是作为一个文件中心,不需要备份

我是设置的raid0,牺牲可靠性,换来空间。
请注意,不管怎么raid,所谓的“备份”是提高你nas的可靠性,也就是说万一坏了一
个,nas还能工作。
但这和你数据的可靠性无关。因为对于你,nas是个黑盒子,它坏了-不论是在哪种raid
下,里面的数据都完蛋了。
所以,你用raid几都可以,看你对空间的要求。一定要用外置硬盘再备份,这样才有数
据的可靠性。

想了想 家用nas 搞raid 1似乎没有任何意义?
不跑什么service,所以可靠性没什么意义
但是又不能保证冗余备份
还白白少了一半空间?

synology的储存管理工具明确的把各种raid 还有它自己的hybrid raid 归在with data
protection这一类
这么说它是认为这种情况data recovery还是可以做到的吧

妈的,synology这么写搞得普通用户很迷茫
到底raid1靠谱
还是两块硬盘相互备份靠谱?

找到这个回答,非常好
我本来想的是raid-1保证可用性,这个我不需要
但是同时也有data 冗余,这个我需要
火灾啥的我即使有外置硬盘也没用
但是这个回答给了一个新情况 -- 主板挂了。。
我不知道nas挂了是不是找个类似型号就ok,但是是个风险,还是自己当两个盘用简单
The value of raid-1 for protecting data is that you can recover from a hard
drive failure quickly.
It is for servers that can't afford any down time.
Recovery from a hard drive failure is just moments.
Fortunately hard drives do not fail often.
Raid-1 does not protect you from other types of losses such as viruses,
software errors, operator error, or fire...etc. If your motherboard fails,
then your raid also fails.
For that, you need EXTERNAL backup. You will want to take an initial backup
of your entire system. Then, implement a policy of taking incremental
backups of data that is important to you.
If you have external backup, and can afford some recovery time, then you don
't need raid-1.

我买NAS主要就是为了Raid1
要只为了容量,直接在router上接硬盘好了

Purpose of raid is to protect you from failure of one disk (or more,
depending on the raid). Backup is to protect you against failure of the
raid itself, such as flooding or fire, or someone smashing your raid box
with a hammer, or accidental deletion of file.
So, the moral of story is: You can live without Raid if you have proper
backup process, but you can't live without backup no matter what kind of
Raid you have.
