Here is, what man bash says:

     When the  old-style backquote form of  substitution is used,
     backslash retains  its literal meaning  except when followed
     by  $, `,  or  \.  The  first  backquote not  preceded by  a
     backslash terminates  the command substitution.   When using
     the $(command) form,  all characters between the parentheses
     make up the command; none are treated specially.

     Command substitutions may be nested.  To nest when using the
     backquoted   form,   escape   the  inner   backquotes   with
     backslashes.
