Trying to back up a system, but dump always ends with the warning
"DUMP: The ENTIRE dump is aborted."  Despite the warning, however, the
partition I'm trying to back up _seems_ (using ls -l to compare the
files manually) to be on the new partition on another disk.

The steps I took were:
newfs /dev/wd1f
mount /dev/wd1f /mnt
dump -f - /var | (cd /mnt; restore -rf -)

and the output to the display is:
  DUMP: Found /dev/rwd0f on /var in /etc/fstab
  DUMP: Date of this level 0 dump: Sat Jun 17 21:57:25 2006
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping /dev/rwd0f (/var) to standard output
  DUMP: Label: none

  DUMP: Volume 1 transfer rate: 2772 KB/s
  DUMP: Date of this level 0 dump: Sat Jun 17 21:57:25 2006
  DUMP: Date this dump completed:  Sat Jun 17 21:57:27 2006
  DUMP: Average transfer rate: 2772 KB/s
  DUMP: Broken pipe
  DUMP: The ENTIRE dump is aborted.

Why those last two lines?

Is there some tool for checking the backup?
