Recently, I often visited the cloud disk forum. Many users reported that after using some functions of the cloud disk, they found that the files they saved in the cloud disk were inexplicably lost. I have encountered several cases of cloud disk file loss. The analysis found that most of the cases were caused by improper use of the cloud disk. Therefore, the use of 360 cloud disk as an example for analysis, and propose specific solutions for your reference. 1. Insufficient understanding of the synchronization folder function: Put the data into the synchronization folder of one computer, but log in to the cloud disk with the same account on another computer, and find that there is no loss of its own data or data. As we all know, many cloud disks can set up a local folder to automatically synchronize folders. If there is data to be saved in the cloud, just save the data to this local sync folder. The rest of the data synchronization work is automatically done by the cloud disk. carry out. Some users think that if you copy the file into this sync folder, you can access the cloud folder in other places. In fact, you ignore a key problem, that is, synchronization also takes time. If you break the network or turn off the computer if the time required for synchronization is not met, it may seem that the names of these files already exist on the server side, but in fact, the upload process is not completed. Therefore, after logging in from the other end PC with the same account, the file cannot be obtained, or only some files that have already been uploaded can be used, and other files are lost due to the lack of synchronization. After knowing this feature of the cloud disk, to avoid this situation, just open the cloud disk client and check whether the synchronization process is completed before disconnecting the network or shutting down the network. If it is not completed, set the automatic shutdown after a certain time according to the prompt and network speed to ensure that the synchronization process of the cloud disk is carried out. Check whether the synchronization process is completed. Some users see the folder and file name to be uploaded in the process of transmitting files to the cloud disk. They mistakenly believe that the upload process has been completed, so in order to save local space, delete Local file. However, it was discovered that the files in the cloud were not used or could not be used, which caused irreparable damage. In another case, after the file is placed in the sync disk, the file is uploaded to the cloud, so the local file is deleted without disconnecting the cloud disk. But in fact, because the file is in the sync folder, the cloud will automatically delete the file in a short time while the file is deleted locally, resulting in the loss of both files. Tip: Even if you disconnect the network after putting the file into the sync folder, then deleting the local file is not safe. Because the synchronization function will still delete the synchronization file on the server side after the next network connection, causing the same files on the local and server side to disappear. If you want to delete a local file after the file is synced to the cloud, it will not affect the files in the cloud. Just set the folder you want to keep to be out of sync. After setting this, you can safely delete the local or cloud files. Will not affect the file on the other end. Set the folder to be out of sync 2. Use multiple terminals to synchronize at the same time and cause confusion. Most of the current cloud disks support simultaneous login and use of multiple terminals in the same account. This way, if multiple computers are set up with a sync folder, it may cause file confusion. For example, deleting a file or folder from this computer, I hope that the server-side files will disappear, but the strange thing is that not only the server-side files have not disappeared, but even the local files have returned. Or if the modified file changes back to the old version. This is the third client cloud disk at work. In order to avoid this situation, it is recommended not to allow the same account cloud disk of multiple terminals to be online and enable automatic synchronization at the same time. If you want to install and use the same cloud disk on multiple computers and use the same account, it is best to set the cloud disk of each computer to not boot automatically, but manually start it when you need it. Also, when using the sync function on each computer, confirm that the data synchronization process has been completed before turning off the computer. In this way, it is possible to avoid the problem of file loss, reproduction after deletion, or version error caused by multi-terminal synchronization. Cancel the boot function of the cloud disk 3. Multi-person shared synchronization function causes confusion Because the cloud disk has the feature of automatic synchronization, if other people operate under the local shared folder, it is easy to delete the cloud file due to deleting or rebuilding the file. Change. At the same time, if multiple people share a computer, it may also cause files that affect the cloud due to local file misoperation. Therefore, it is recommended that the cloud disk sync folder be used on a personal computer that you use alone. On a public computer in an office or other location, do not use the cloud disk to automatically synchronize personal data. If you need to use a cloud disk on a public computer, the best way is to access it through the web version, and choose not to save the username and password when accessing, and do not choose to log in automatically next time. In addition, it is best to set the browser to a seamless browsing mode so that the computer does not leave any traces after exiting. In terms of data security, it is a more secure approach. Accessing the cloud disk from the web version Tip: Accessing the cloud disk file from a computer with a light cloud disk client installed will not cause file confusion. However, it should be noted that the current cloud disk light client, some also have the function of automatically syncing files. If you use the cloud disk light client on someone else's computer, remember to log out of someone else's account and log in with your own account. (Also remember that you can't save your password), and don't set the sync folder at the same time, so as not to cause confusion of the data. Use the light disk client to use the cloud disk knowledge: about the file "seconds" in the field of cloud disk, there is a "second", the word that means to transfer a certain material from a certain place to the cloud disk space In the middle, regardless of the size of the data, the transmission time is calculated in seconds. This is true in the case where the "cloud" is transmitted to the "cloud" or the cloud file is identical to the local file. For example, download a file shared by a user with a 360 cloud disk to its own 360 cloud disk, or upload a local file that already exists in the cloud to the cloud disk. In this case, only a positional pointer is actually transmitted, and no real file copying action is performed. However, if you want to transfer to a unique file to the cloud disk, this "second" is not realistic. If you see your own unique large file in the blink of an eye, it is an illusion that the real transmission process is not completed.
