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.
