ReaR: backup using tar always succeeds, even in case of tar error

Solution Verified - Updated -

Issue

  • When backing up using the NETFS and tar option, backup errors are not detected, ReaR continues and displays the following message

    WARNING: tar ended with return code 1 and below output:
  ---snip---

  ----------
This means that files have been modified during the archiving
process. As a result the backup may not be completely consistent
or may not be a perfect copy of the system. Relax-and-Recover
will continue, however it is highly advisable to verify the
backup in order to be sure to safely recover this system.
