[操作疑難] 新手問題 2BAY NAS 唔行RAID 一隻平時用一隻當BACKUP...

請問可唔可行?
追POST 話兩隻HD行 RAID 1 一樣會照死DATA
所以最好NAS + USB HD BACKUP

咁如果我買隻2BAY,但平時只用其中一隻做串流同DOWN LOAD,
另一隻剩係間中用黎BACK UP BB相同生活影片,(即係重要DATA放晒兩BAY)

咁樣會唔會比較接近NAS加另外BACK UP?
定係同用RAID1一樣會一齊死DATA?

如果都會一齊死咁我買1BAY + 外置算
如果唔會既話一次過買2BAY整齊好多

新手問題唔好插得咁大力THANK YOU

1. If you don't plan to use RAID-1, no need to buy 2-bay NAS.

2. If you're worried about NAS stability to ruin your data, never use beta firmware.

3.

忘記左LO,好多人話RAID唔同BACKUP,好多時一死就一齊死DATA咁講。

Raid 1 is for data redundancy, it is NOT a kind of backup (ppl at epc have already mentioned ... again and again and again)

For ordinary home use, the most simple backup approach is using an external portable hdd.  To make two backup copies, then you will need two external portable hdds.   Of course there are other backup alternatives ...

1-bay, 2-bays, 4-bays or else ... it's really up to personal need.   For instance, if you have a 4-bays nas, you can easily increase your total storage capacity by adding more hdds.  However, budget is always a matter of concern (to many).

Anyway, it seems computer shops do not normally hold S/Q 1-bay stock (冇現貨 ... no good selling?).  In case you're interested to get one, you may need to place an order.

我會行raid 1 +ext hdd 做backup雙重保護

其實兩隻獨立運行再加埋兩者之間做backup……個人覺得重衰過行RAID1…

其一無咗你死一隻時未backup好的資訊就拜拜了……
其次係當你遇到system wide嘅fail時,例如ransomware又好丶手多跌爛部nas又好丶唔小心倒瀉杯水落去又好丶一個行雷就KO你兩隻碟了……

行一隻再加一隻碟做backup,其實係取哂所有兩者raid1+backup的缺點……

最佳的方法永遠都係行RAID再加外置offline backup,backup且最好有多份copy添!
