I have already waded through this water, the following is my experience, and my public account: random buying guide, thank you for your attention:
The function of NAS syncing folders must be the most important requirement of most NAS users. I purchased Synology DS218+ two months ago. In the two-month home office, the company's notebooks are synchronized in both directions, and the local area network of the home desktop computer is synchronized in the local area network. The files in the NAS, not to mention how convenient, how happy, so when I resumed work, I lost another 8T cool wolf, and the 4G memory added bricks and tiles. Just when I was picking up the data, the data backed up by two months of work was lost, and listen to me slowly. come. . . . .
1. Turn off on-demand synchronization on Synology Drive
Synology Drive is the software for synchronizing files on Synology NAS. When setting the synchronization plan for the first time, click this step to set the folders that need to be synchronized in the cloud and local. If there is no problem with the settings, click Next. There is a switch in the advanced settings. One time use without attention:
In the synchronization mode, the last item: "Enable on-demand synchronization to save hard disk space", this tricky function is actually enabled by default. Let me explain to you what this function means: After opening, it is necessary to open the synchronization function folder. The downloaded files will only be kept on the NAS, and will not be automatically downloaded to the local machine. If the files on the NAS are modified, and the synchronized folders are accessed from the local machine outside, they will not be downloaded. What is the problem? Below is my case.
My work laptop stores company files. By synchronizing the work folder, I upload the files that I complete every day of my work to my NAS. I don’t need to bring a laptop when I go home, and I use my home desktop to access the synced files in the NAS to continue. At work, I go back to the company and use a notebook. The files completed at home will not be downloaded automatically. The small cloud below will be displayed on the file. When I open the conference, I will download the data updated at home yesterday. There are many content tables and documents in my company, and the data may be It will be very large, and the company's intranet is very slow to open. In the past two months, I used the desktop computer to log into the NAS folder to do things. After I went to work, I used the laptop. Everything completed in the two months needs to be downloaded again.
This is nothing. The story happened after I bought a new hard drive. Synology NAS is a Linux system, and it is a bit troublesome to transfer data. Du Niang searched some articles, and they all suggested that all data be backed up and then transferred to the hard drive. I think I The notebook has a backup, so it should be no problem, but my notebook is a two-way sync folder, so I turn off this function (self) and turn it off (make) and it will be good (cong), and after turning it off, I will put the NAS home/Drive folder. I deleted all the things I backed up, reinstalled Drive and backed up all of them again. It's foolproof. As a result, I opened the office the next day and completed the work on my desktop computer for two months. Only the folder was empty. . . My mind went blank, and I recalled the concerns I had before buying a NAS - losing data for the sake of data protection is as stupid as me
2. Cloud Sync XX cloud disk one-way synchronization
Many people choose to synchronize two copies of NAS and XX cloud disks. It is strongly recommended that the synchronization direction in the synchronization direction setting be selected as "upload local changes only". This function is that I saw users delete and modify files in the cloud disk during the process of migrating. , modify the files in the NAS, and then modify the data on the local side. Therefore, the cloud disk is relatively large, so save more points, so as to avoid problems that affect the efficiency, and the gains outweigh the losses.
The third point to note is that important folder backup, if the space is acceptable, it is recommended to turn on the Recycle Bin function, the specific location: Control Panel--Shared Folders--Select your own key protected folders--Select above Edit -- Enable Recycle Bin.
Summary: 1. Turn off "Enable on-demand synchronization to save hard disk space" for syncing folders in Synology Drive, unless there are special usage scenarios; 2. Cloud Sync turns off the permission to modify NAS sync files on the network cloud disk; 3. For important files in the NAS Folder to increase the recycle bin function.
