ReaR works only on the eth0 interface
ReaR produces a rescue system that does not support mounting an NFS server using an interface other than eth0. Consequently, the backup files cannot be downloaded and the system cannot be restored. To work around this problem, ensure that the used interface is eth0 by restarting dhclient. (BZ#1313417
ReaR creates two ISO images instead of one
In ReaR, the
OUTPUT_URL directive enables specifying location for the ISO image containing the rescue system. Currently, with this directive set, ReaR creates two copies of the ISO image: one in the specified directory and one in the
/var/lib/rear/output/ default directory. This requires additional space for the image. This is especially important if a full-system backup is included into the ISO image (using the
To work around this behavior, delete the extra ISO image once ReaR has finished working or, to avoid having a period of time with double storage consumption, create the image in the default directory and then move it to the desired location manually.
There is a request for enhancement to change this behavior and make ReaR create only one copy of the ISO image. (BZ#1320551)
