Xiaobai getting started with NAS - quick building private cloud tutorial series (I) [easy to understand]

Hello everyone , I meet you again , I'm your friend, Quan Jun .

What is? NAS

In daily work life , We have a lot of information 、 Files need to be stored in computers or other terminal devices , But this method requires the computer to be equipped with a high-capacity hard disk , And you need to carry it anytime, anywhere , Is that a lot of trouble ？

that , today , Let me introduce a family private cloud —NAS, adopt NAS, We can access the information we have stored in... Anytime, anywhere through the web NAS The documents inside .

that , What is? NAS？

Let's first look at the official answer .

NAS（Network Attached Storage： Network attached storage ） Literally, it means connecting to the Internet , Device with data storage function , So it's also called “ Network memory ”. It's a dedicated data storage server . It's data centric , Completely separate the storage device from the server , Centralized management data , To free up bandwidth 、 Improve performance 、 Reduce total cost of ownership 、 Protect investment . It costs far less than using server storage , But the efficiency is much higher than the latter .

NAS It can support multiple protocols （ Such as NFS、CIFS、FTP、HTTP etc. ）, And it can support various operating systems . Through any workstation , use IE or Netscape The browser can NAS Intuitive and convenient management of equipment .

NAS Connect the storage device to the existing network to provide data and file services .NAS Servers generally consist of storage hardware 、 The operating system and the file system on it .NAS Connect the disk storage array directly through the network , The magnetic array has high capacity 、 High efficiency 、 High reliability, etc .NAS Connecting storage devices through a standard network topology allows you to access the Internet directly without a server , Not relying on a common operating system , Instead, it uses a user - oriented design , A simplified operating system dedicated to data storage , Built in protocol required for network connection , Thus, the management and setting of the whole system are relatively simple .

Let's discuss it more popularly .

NAS Colloquially speaking , Is to use a special computer with a palace capacity hard disk device , Install the file storage management service software , Through wired network or wireless WIFI For mobile phones 、 The computer 、 TV box 、IPAD And other devices provide remote access to data 、 Backup and data synchronization functions . Mainly used for storing photos 、 music 、 Movies, TV series or BT High speed download 、 Network disk data backup and download functions .

As a household NAS The server , Let's analyze the following characteristics ：

• You can remotely control the server on and off , And the server is the best 24 Turn it on every hour , It is convenient to access the data in the hard disk anytime and anywhere , Low power consumption, power saving and low noise .
• You can access... From the public network , And configure SSL certificate , Ensure the security of the server
• No high-end configuration is required according to the demand （ Introductory series , Low performance requirements ）, therefore , Obsolete computers 、 The notebook 、 Raspberry pie 、 Router （ Engineering machine ） Can meet basic needs , It is best to support the machine phase of multi hard disk array , Configure a hard disk large enough to store data and data redundancy .
• Because it is usually remote access , So it's better to have a high-speed Gigabit export router , It's better to support 5G Frequency band WIFI Router .

NAS Usage scenarios of

We may have used some services of other Internet manufacturers ：

• Photos on your phone 、 Upload documents or some important information on the computer to Baidu cloud , Uploading is super fast , But when downloading, it's so slow that I doubt my life （ Baidu cloud disk needless to say , Everyone knows 【 dog's head 】）, Or other cloud services , Access and play online through web pages or clients , However, due to non member restrictions, the speed and storage space are too small , The experience is terrible ;
• We often pass through QQ File transfer or other transfer tools to share photos with family , Or use U Disk transmission , The process is very complicated , And the update of photos also needs to solve the problem of duplicate or missing files , It's a headache ;
• Downloaded songs and video materials , Nowadays, the awareness of copyright is strengthened , It is difficult to find resources for some content on the Internet , It can only be stored on the computer hard disk or mobile phone , But due to the limited capacity , It's not easy to store too much data , Playing and sharing are more troublesome , If you can connect the TV box through the server, it will play automatically , That experience was very good ;
• The stored information involves privacy , The public cloud is prone to data leakage , So choose NAS It's a good choice ;

family NAS Basically, it is to solve the problems in the above scenario

• Files are stored centrally , As a home data center , Plug in a mechanical hard disk with sufficient capacity , Photos of families scattered 、 music 、 Film and television materials synchronize the mobile phone through wired or wireless LAN and perform cold backup or hot backup , Free the space of terminal equipment ;
• NAS Provide SMB、FTP、webdav And other agreements to share files with family members , And you can set different permissions for everyone . The ability to provide remote access , Let's go anywhere, anytime, in any environment , Can access files without restrictions ;
• take NAS Store at home , Gigabit LAN access upload and download speed up to 100M/s about , It is not limited by the upload and download speed of broadband operators . Whether it's online audio and video playback or photo backup browsing , Are far better than using cloud disk services with various restrictions .

NAS Is it safe?

What if the hard disk breaks ？ Is the data safe ？

• Make use of disk array RAID programme , Set different schemes according to personal considerations for speed and data security , for example RAID 0, Even if a hard disk fails, it can easily ensure that data is not lost ;
• Using public cloud services , Automatically upload local important files to cloud storage space , Even if NAS Sudden downtime , But cloud data can also reduce losses as much as possible ;
• Set timing task , Automatically back up the contents of important folders when the mobile hard disk is inserted , Periodic reminders , Back up regularly every month ;

So the use of Private cloud + Public cloud The plan , It can better ensure the integrity of data .

Whether to disclose privacy ？

• Most of the NAS be based on Linux System ,Linux Less system virus , Safe and stable ;
• With high privacy requirements, you can completely close the remote access exit , Home LAN as long as the router is safe , The possibility of being attacked or leaked is very low ;
• Upload files to the public cloud space. You can encrypt the files before uploading , Decrypt locally during synchronization , Both data security and privacy can be guaranteed ;

NAS What are the products

NAS Various forms , Of course, the positioning is different , You can buy suitable hardware according to your needs , Then install the open source system 、 Software customization ;

It is generally divided into the following two schemes ：

• Buy hardware and send system plus software
• Do it yourself DIY Hardware and install open source systems （ I am ）

I personally prefer Qunhui products , Qunhui is positioned as an enterprise storage solution , also 6.X Then better support Docker、 Convenient Suites such as virtual machines , And configured and developed mobile phones 、PC、MAC End software , Worry free, powerful .

Generally speaking , Qunhui is divided into two kinds , White Qunhui and black Qunhui , Baiguohui refers to purchasing the genuine hardware of Qunhui and supporting systems and services , Black Qunhui refers to Qunhui that doesn't buy genuine products NAS, Install Qunhui on ordinary computers or workstations NAS System , Heiqunhui gives you a packed NAS、 Comprehensive lightweight system , Easy to use . Yes, of course , The black glow can also be washed white , interested , Have time to publish a whitewashing tutorial .

Qunhui's practical is DSM（DiskStation Manager ） System , It can help users manage the storage in Synology DiskStation and RackStation Files in 、 Photo 、 music 、 Videos and other important content .DiskStation Manager What can be realized is not only storing data , Users can also set up applications and choose the services they need , Enrich life and improve work efficiency .

Finally, leave a suspense , Take a look at my NAS Server, haha

Conclusion

Today is about NAS This is the introduction of , The theme of the next article is how to choose and DIY Hardware 、 How to install heiqunhui system , Interested friends, click to follow me .
