Hello everyone I have such a question

I fell in love with this program because of the open source code, but I have a question. When I synchronize files, for example, if the Internet or Computer is disconnected, does the backup copy fail or does any kind of error appear? Or the program itself will continue to re-download the file where the process was destroyed?

I’m talking about a sudden unexpected shutdown.

There might be some language issues here. Duplicati doesn’t synchronize the way a sync program does (keeping the same files at source and destination) however an interrupted backup is supposed to resume where it left off after figuring out where it is. It then continues to upload (meaning send to destination) files representing the backup of source data. The format of the files is not the original, but designed for backup.
