When mirroring, I'm curious to know if existing files are updated by adding only the new bytes (aggregated) or if the entire file is replaced with the latest copy?


In other words, if an 800mb file increases to 810mb from the last time it was backed up, will only the new 10mb worth of supplemental data be backed up or will the entire 800mb file be deleted and replaced by the most recent 810mb copy?

Hi,


FBackup will copy the entire modified file, not only the new bytes.
