Mirror backup does not keep single file in container file

[DomiChi]

I Mirror backup description I read:
While the other backup types collect all the files and folders being backed up each time into a single compressed container file, a mirror backup keeps all the individual files separate in the destination.
Then I did a mirror backup.
But as result I obtain a 4Go ZIP file. What append to ALL the files in this ZIP file if this big ZIP become corrupt?
