Currently, working around this, with tmpdir for both xtrabackup and innobackupex:
/usr/sbin/innobackupex --defaults-file=/pxc56/etc/my.cnf.local --no-version-check --tmpdir=/tmp/tmp.IhuFVZftFn --socket=/pxc56/datadir/pxc.sock --galera-info --stream=xbstream /tmp/tmp.mUBsJCxrld
However, two bugs remain in this:
a) option_tmpdir being used by innobackupex than option backup_dir (/tmp/tmp.mUBsJCxrld)
b) That innobackupex/xtrabackup hang when it fails.
