A start of the sync can be done by external application (Tasker, AutoMagic etc) or SMBSync2 schedule. Mirror: If master and target files are different, to copied files from master to the target directory. To delete target files and directories if does not exist in the master. Move: If master and target files are different, to copied files from master to the target directory. To delete the master directories and files copied to the target. However, the master and target same name, same file modification time and file size, to delete the file on the master without copying files. Copy: If master and target files are different, to copied files from master to the target directory. However, the same file modification time and file size with the same name does not copy the master and target. Archive: Move photos and videos in the directory on the master side to the target under conditions such as shooting date/time than the date and time of archive execution, such as 7 days or earlier or 30 days or earlier.
