This function copys the content of a container disk,
with the following parameters
--stats "give some file-transfer stats" for print output
--sparse "handle sparse files efficiently"
--whole-file "copy files whole" to need less ressources
--archive "-rlptgoD" to call this para
--acls "preserve ACLs"
--xattrs "preserve extended attributes"
--hard-links "preserve hard links"
--one-file-system "don't cross filesystem boundaries"
--numeric-ids "don't map uid/gid values by user/group name"
