how to easily backup between two folders, and only save new files, not replace the files that have been backed up. In fact, there are a lot of software available, and personally think that it is more appropriate to "single file synchronization backup system". The following system home is introduced in detail for everyone. I hope to be helpful to readers with the same needs. Start the software after the software is installed and set it up. First click the “New Task" button in the program interface to open the “Type & Name” dialog box. In this dialog box, select the type of task you want to perform. According to the requirements of the topic, we select the type of “Accumulate Synchronization” and enter the name of the task. Click “Next”. In steps 2 and 3, select the source folder directory to be backed up and the destination folder directory where the backup files are saved. The next steps are some options for the task. Readers can do it according to their actual situation. Choice, the author does not introduce every step. However, as far as the requirements in the title are concerned, the author believes that in the “automatic execution” setting (Figure 2), we need to select “daily” or “interval” to achieve convenience. This requirement ((the software defaults to “manual” mode). If the computer configuration is relatively high and the file sending and receiving frequency is relatively dense, then you should select “ldreal” in real time. In real time mode, whenever When the source folder directory file changes, the backup tool will automatically perform the backup task after the set delay time, so the delay time should not be too long or too short. It should be set according to your actual situation, such as the source folder directory. Each time the file is sent and received is large, it takes a long time to set the delay time a little longer, but if the file is backed up each time, the delay time can be set shorter, so that the source folder directory can be avoided. The file has not been sent or received, the backup work has already started and the backup failed. In addition, the settings in the "Automatic retry" dialog box (such as c), the author believes that there is some connection with the above selected mode of "automatic execution". If the above mode is selected, "daily" or "manual", then you should select "by number". Retry until it is completely successful, and set the interval and number of retry attempts to prevent the backup from failing because the file is being used by other programs. For example, select “interval" or “realtime” Select “Do not retry and wait for the next execution. The method is not recommended. Unless there are special needs, it is recommended not to check the option “Unlimited retry until it is completely successful”. Also, for the convenience of the task. Request, we should also check the "Use the bubble window to prompt the task before and after the task execution" in the "General Options" dialog box. After the check, each time you perform the backup work, you will be prompted, even the result of the execution. It will also be presented in the pop-up window, which makes it easy for us to see the backup work at a glance. In addition, after the task is established, if there is any design If it is not suitable, we can modify and perfect the task to make it more in line with our requirements. Finally, I would like to remind you that because there are many people using the NTFS file system in the partition, we also use it during backup. To pay attention to the issue of permissions, the logged-in user must have read access to the source folder directory, and write permissions to the target folder directory to ensure the smooth backup.
