@@GarionPhotoTechbtw the point u said clone important data to different folder does not actually make sense because they are still under the same raid controller and, the same NAS.
@raychan3304 well, I have another copy in my other HDD. If that Nas is completely dead, you are right. Not much data can be saved. As I said, that nas is not my only solution. Just everyone has a limited budget. If you have 9000 HK dollars that is very difficult to 321 to do a backup for 40TB. Not impossible just difficult. So, in short answer to your long reply, everyone need to check the best solution to store as much data as they can.

UP主所說的NAS 傳輸到ECC內存等問題SYNology都係可以解決到,而且重要資料最好冷備加熱備份,如果條件可以可以推多部NAS 我個人加上公司就有5個NAS ,有好多唔同牌子,結論係以係都係買返SYNology,由快照,備份方法,到各方便都係佢最好,佢只有一個問題就係貴
其實用係備份的NAS 不需要買最新一代 買上兩代的就最化算 最好買二手 價錢5成左右可以買到 我宜家都係咁用.
1)NAS 最大用途只是用來分享檔案及數據，絕對不適合保存數據 !
2)用 raid 並不安全，當你用raid 5 或 6 來回復壞碟數據時，機器在漫長時間加大容量數據恢復，往往會做成陣列內其他硬碟損壞 ! 到時就乜都無晒 !
計算出錯是因為軟件 raid
3)NAS 硬件有問題時，不能簡單解決，PC 開唔到機，還可以隨便把硬碟搬到另一台電腦讀取，NAS 開唔到機，當你硬碟無壞都要搵同款機型來讀取資料，如果行RAID仲有可能開唔返要修護 !
4)PC 大把簡單易用可靠程式用來備份資料，包括由手機到電腦，如果要經常存取NAS Data 來工作，用網線點都唔及電腦硬碟內讀寫快速 !
要保存及備份資料，直接用硬碟吧 ! 唔好听D傻佬講買多1部NAS來備份先前NAS，人傻錢多另計 !
有無可能：有兩個唔同牌子硬件嘅NAS，在第一個NAS建立一個RAID，然後將呢個RAID從第一個NAS中拆出嚟，再將呢個RAID連接到第二個NAS，咁之後第二個NAS能夠完全認出呢個RAID。好似話FreeNAS可以做到。各位有無試過？
@tubemate4862 唔同牌子呢個機會有可能唔得。除非你用freenas 或truenas.
有另一個方案可以嘗試。Ceph. 呢個方案可以讓不同的nas牌子共同一齊工作。我自己沒有這方面的實質經驗可能你要找一下這一方面的資訊.
@@tubemate4862建議選擇一個大牌子嘅NAS，hardware有乜事成set HDD 搬去同品牌新d 嘅model就ok， cross system風險一定大
NAS 都係多數S牌 or Q牌 ?
@1oT3To1 的確大部分鏡會選擇Synology或Qnap. 如果喺兩個大品牌之間選擇我會揀返synology。我揀asustore 最主要原因係因為平。佢唔可以話非常好。但係除咗相片庫之外其他功能都做得唔錯。而家我嘅相片管理用另外一個軟件叫做immich. 呢個軟件可以好似google咁有ai去分析所有嘅物件係啲乜。但係坦白講佢冇google咁勁。
無論RAID5/6/10都好, 張底板壞左都一樣TOTAL LOSS! 所以HARDWARE既FAULT TOLERANCE不能取代BACKUP去另一個獨立Storage System/Medium.
不是，如果只是NAS底板壞了，你只要買另一隻同牌子同級數或更高，把HDD插到新NAS是可以復原的，Synology就是這樣，Qnap相信也是這樣。
@@himenlam4120非常高風險的，除非你一早買兩隻機同款式，不兼容的話你就捉蟲。
Good morning Garion . Thanks for sharing . 💯💯💯💯💯💪💪💪💪💪 .
Thank you for your support. 🙇
Raid 5應該係最少3個hd，4個係raid 5 + spare
Very good information
以你嘅data量，強烈建議撇除價錢喺考慮因素之外，並參考多啲世界各地中伏用戶嘅網上分享。
其實坦白講無論用哪一種系統都有機會唔見檔案。長遠的話還是需要多一台off site nas. 但現在的情況應該足夠應付。多謝你的建議。

@@GarionPhotoTech我覺得最正係擺一部 NAS 係老母屋企開 openvpn 用 rsync over ssh 每日自動 sync 過去做 offsite backup 😂

@@GarionPhotoTech Yes, Raid is for avoid service interruption. When hardware failure you will have time to fix the problem. Never use RAID as backup.

行RAID仲要有UPS 防止停電
多謝分享🙏😁
Raid 5 最少應該係3隻 HDD 而唔係4隻？？？
會唔會用FTP過file 會好D?以前用FTP過file 去NAS 都好穩定
這方面我不能肯定好似 google drive 並沒有支援ftp. 😭
我就係噉樣 FTP 可以開10個都得 同一時間10個資料夾傳送 FTP中有一個好處 相同資料不會傳送
@@GarionPhotoTech 不支持的 呢個方法係適宜由電腦到NAS
45TB data? 😮😱
😆 講下硬件野可以留下言啦
資料備份如果BACKUP 多一份 如果可以 做多一份異地+離線備份 會更好
備份既野多多益善 資料無價
多謝師兄嘅分享。事實上將檔案分去兩個實體地方會較為理想。喺我角度例如阿媽屋企😜。外母屋企應該都得。
13:08 這裡說的「NAS計算會出錯」 , 可否講多少少 ?
我真的未聽過NAS會計算出錯
一般入門版的nas並不會使用ecc memory. 所以再計算資訊的時候是有機會出錯。另外一個情況是當一些硬盤時間太耐, 可能出現個別的讀取錯誤。雖然parity bit 應該可以糾正這種錯,但是對一些絕對不能出錯的資訊大家還是小心點。始終地球係唔會有完美嘅嘢嘅。希望這個可以幫到你。
多囉…. 用 ECC ram 嘅就有保障D
@HongKong880 多謝師兄嘅分享。如果揀nas可以選擇有ECC ram 去更加有保障。
@@GarionPhotoTech 老實講，我建議自己郁手砌 unraid server
GCP cloud storage is another option
雖然係轉左落黎。但都要整多個 offsite copy。 會唔會都係要用返 google。 或者搵ｄ 平ｄ 方案。。 onedrive 會唔會平ｄ?
應該會用off site. 將個重要硬盤放喺阿媽屋企😜。
RAID-6 容錯兩隻硬碟更安全
多謝你的分享👍。好似師兄所講RAID 6 更加安全。大家也可以考慮這個方案。這種方案需要兩隻眼本做容錯。硬盤方面仍需求最少四隻。總容量只會有兩隻的空間。😁
對於沒應付過執行ERP, SQL 數據庫 的環境,業餘人任會對raid有錯誤的理解和幻想。raid的出現係針對 SQL 大數據的情況，一個SQL 檔案是幾十G或數百G以上,而且ERP 運行時需不斷讀寫不能停頓的熱數據,那當時只有幾十G 的HDD 不能勝任,只好用不同的方式串連，繼而制定raid的規範，但HDD 容量達幾百G時，raid5的問題就開始浮現....
對於相片或其它較細檔案(千M以下)的冷數據，以現今HDD, SSD 的容量，速度，raid5 係明顯不合適的。
@@GarionPhotoTech 👍yes raid6 會更加安全 硬碟數量最少4隻 硬碟容量計算是 N隻硬碟數量 減去2隻硬碟做容錯運算
我自己就是用8隻硬碟 行raid6 8-2=6隻硬碟總容量
raid卡是電腦用pci-e硬體運算卡
提提你 有無諗過你用的asustor nas硬體機 會有壞的一天 如果用三數年後壞掉 才再買一個新的 是一定不能匹配的
所以硬體機器亦都要即時兩份
@@mobilephone8312 照我所知假如Asustor的Nas的機體壞了，只要硬碟無壞，買翻同廠相同盆位的新Nas，插回同一硬盆位置就可回復之前一樣，包括所有數據設定！
可向代理查詢！
我自己放一套落ssd
一套落5T hdd
ssd防跌
hdd放耐少少
可惜usb tape drive貴
我將會在一兩年內將部分重要的資訊分別放在兩個SSD。做cold storage, 這樣損毀的機會應該較細。

點解可以有咁多相？？😮
只因自己亂影太多!😅
80萬張相，當你唔知幾時開始有時間睇返啲相，一秒睇一張，不眠不休不吃不喝不疴屎尿，要超過9日先可以完成。
@roycheers hahaha. 你講得啱其實好多時都冇睇返啲相。只係萬一要用嘅時候先至去睇。
Raid5 好大鑊,因常要平均數據, HHD 常抄寫,好快死,而且當一只出問題,其他的時間也差唔多,當換一只新的時間,未sync好另一只又出問題,那就玩完了。
如果擔心這種情況可能要使用Raid 6.
@@GarionPhotoTech 呢D經驗纲上可查，現儲存公司多用jbod + raid 1 或 双機冗餘
