  An expression for the average redshift drift in a statistically homogeneous
and isotropic dust universe is given. The expression takes the same form as the
expression for the redshift drift in FLRW models. It is used for a
proof-of-principle study of the effects of backreaction on redshift drift
measurements by combining the expression with two-region models. The study
shows that backreaction can lead to positive redshift drift at low redshifts,
exemplifying that a positive redshift drift at low redshifts does not require
dark energy. Moreover, the study illustrates that models without a dark energy
component can have an average redshift drift observationally indistinguishable
from that of the standard model according to the currently expected precision
of ELT measurements. In an appendix, spherically symmetric solutions to
Einstein's equations with inhomogeneous dark energy and matter are used to
study deviations from the average redshift drift and effects of local voids.
