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:

of trying to directly create the snapshot itself. This change allows
users logged into the system as operator to run live dumps.
Note that dump no longer tries to create the snapshot in the root of
the filesystem, but rather in a .snap directory in the root of the
filesystem. The reason is that the operator is usually not permitted
to write into the root of the filesystem. The newfs command and
background fsck have both been modified to create a .snap directory
in the root of the filesystem, but if neither of these have been run,
then the .snap directory must be created manually by the superuser
before a live dump can be run. The .snap directory should be owned
by user root and group operator and set to mode 770.

1024-byte boundaries. For many years this was a reasonable
assumption. However, in recent years we have begun seeing
devices with 2048-byte sectors. These devices return errors
when dump tries to read starting in the middle of a sector
or when it tries to read only the first half of a sector.
Rather than change the native block size used by dump (and
thus create an incompatible dump format), this fix checks
for transfer requests that start and/or end on a non-sector
boundary. When such a read is detected, the new code reads
the entire sector and copies out just the part that dump
needs.

called -r but it takes 512 byte blocks instead of megabytes, and I felt a
megabytes specification would be far more useful so I did not use the same
option character.
This will *greatly* improve dump performance at the cost of possibly
missing filesystem changes that occur between passes, and does a fairly
good job making up for the loss of buffered block devices. Caching is disabled
by default to retain historical behavior.
In tests, dump performance improved by about 40% when dumping / or /usr.
Beware that dump forks and the cache may wind up being larger then you
specify, but a more complex shared memory implementation would not produce
results that are all that much better so I kept it simple for now.

live filesystem. To obtain a consistent dump image, dump takes
a snapshot of the filesystem and then does a dump of the snapshot.
The snapshot is removed when the dump is complete.
Also add an operator warning that the `L' option should be used
if dump is run on a live filesystem without the `L' option being
specified. The alternative would be to silently use a snapshot
any time that a live filesystem is dumped, but this change in
dump semantics seemed too drastic at this time.

the old 8-bit fs_old_flags to the new location the first time that the
filesystem is mounted by a new kernel. One of the unused flags in
fs_old_flags is used to indicate that the flags have been moved.
Leave the fs_old_flags word intact so that it will work properly if
used on an old kernel.
Change the fs_sblockloc superblock location field to be in units
of bytes instead of in units of filesystem fragments. The old units
did not work properly when the fragment size exceeeded the superblock
size (8192). Update old fs_sblockloc values at the same time that
the flags are moved.

filesystem expands the inode to 256 bytes to make space for 64-bit
block pointers. It also adds a file-creation time field, an ability
to use jumbo blocks per inode to allow extent like pointer density,
and space for extended attributes (up to twice the filesystem block
size worth of attributes, e.g., on a 16K filesystem, there is space
for 32K of attributes). UFS2 fully supports and runs existing UFS1
filesystems. New filesystems built using newfs can be built in either
UFS1 or UFS2 format using the -O option. In this commit UFS1 is
the default format, so if you want to build UFS2 format filesystems,
you must specify -O 2. This default will be changed to UFS2 when
UFS2 proves itself to be stable. In this commit the boot code for
reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c)
as there is insufficient space in the boot block. Once the size of the
boot block is increased, this code can be defined.
Things to note: the definition of SBSIZE has changed to SBLOCKSIZE.
The header file <ufs/ufs/dinode.h> must be included before
<ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and
ufs_lbn_t.
Still TODO:
Verify that the first level bootstraps work for all the architectures.
Convert the utility ffsinfo to understand UFS2 and test growfs.
Add support for the extended attribute storage. Update soft updates
to ensure integrity of extended attribute storage. Switch the
current extended attribute interfaces to use the extended attribute
storage. Add the extent like functionality (framework is there,
but is currently never used).

in cases where the supplied name was already pointing to a character
special device. This fixes the breakage that occured when trying to
dump a filesystem by name (e. g. /usr), with an fstab already
mentioning the raw device name (like /dev/rda0g) where dump attempted
to use /dev/rrda0g then.
Also removed the now obsolete remark that fstab were carrying block
special names.

so physio's limits aren't touched.
Since this check was originally from me, I feels safe now to back it
