Brian Feldman c51d70c690 Add -P arguments for dump(8) and restore(8) which allow the user to ... use backup methods other than files and tapes. The -P argument is a normal sh(1) pipeline with either $DUMP_VOLUME or $RESTORE_VOLUME defined in the environment, respectively. For example, I can back up my home to three DVD+R[W]s as so: Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ad0s2e 40028550 10093140 26733126 27% /home green# dump -0 -L -C16 -B4589840 -P 'growisofs -Z /dev/cd0=/dev/fd/0' /home		2004-04-13 02:58:06 +00:00
