![]() When fastcopying directory trees (or entire mtrees) if the destination directory (or mtree) already exists the destinations current content will be removed and replaced by the results of the fastcopy command. Files created by fastcopy will de-duplicate perfectly against existing data on disk (as they will reference the exact same physical data as source files) - due to this compression statistics for the files may show inflated ratios.Fastcopy of each file is extremely quick (as the operation only involves manipulation of file metadata and no physical backup data is read/written to disk) - it is much faster than using an external client to read source files/write destination files.Cloning the metadata of existing files at the location given as the source to the new files at the destination.Creating a brand new file/set of files at the location given as the destination. ![]()
