• Brief description of the issue
  I would like to make ISO for backup/restore operations. When I use above settings, the error was returned, because of /var filesystem full. I found that the ISO file was generated under /var/lib/rear/output. That is expected behavior, even through I define OUTPUT_URL=file:///fsbackup/?

### command output ###
# $  ls -l /var/lib/rear/output/rear-cdctst1r_01.iso

I tried

OUTPUT_URL=null
ISO_DIR=/expect_output/output/

and then rear would not put iso in /var/lib/rear/output, instead rear put iso to /expect_output/output/ directly.

Needinfo: @jsmeix @gdha Is above the right way to redirect iso file?

See also issue #734 - however, still haven't found the time to implement this feature.
@feichashao Yes - the work-around you're using seems to do the job for the moment.

@feichashao as your work-around is sufficient for the moment and issue #734 is still open for the same we can close this case.
