C.f. default.conf:

##
# TMPDIR
#
# Relax-and-Recover needs a (temporary) working area where it builds in particular
# the rescue/recovery system ISO image (and perhaps even stores the backup archive).
# The directory name of the working area is created in /usr/sbin/rear by calling
#   mktemp -d -t rear.XXXXXXXXXXXXXXX
# which usually results /tmp/rear.XXXXXXXXXXXXXXX or $TMPDIR/rear.XXXXXXXXXXXXXXX
# the latter when the canonical Linux/Unix environment variable TMPDIR
# is set in the environment where /usr/sbin/rear is called.
# To have a specific working area directory prefix for Relax-and-Recover
# specify in /etc/rear/local.conf something like
#   export TMPDIR="/prefix/for/rear/working/directory"
# where /prefix/for/rear/working/directory must already exist.
# This is useful for example when there is not sufficient free space
# in /tmp or $TMPDIR for the ISO image or even the backup archive.
# TMPDIR cannot be set to a default value here, otherwise /usr/sbin/rear
# would not work in compliance with the Linux/Unix standards regarding TMPDIR
# see https://github.com/rear/rear/issues/968

See the documentation,
e.g. from "man rear":

See the default configuration file
usr/share/rear/conf/default.conf
for an overview of the possible methods
and their options.
