693c40a39a When using dump to generate level 0 dumps which are then rsync'ed
to a remote machine, the fact that the dump date is stored with
each header (inode) record makes rsync significantly less efficient
than necessary. This also applies to inode access times when they
are not important data to retain. When implementing an offsite
backup solution of this type, these dates in particular are not
important, especially if it prevents effective offsite backups.

772ad651bf Update the dump program to save extended attributes. Update
the restore program to restore all dumped extended attributes.

If the restore is running as root, it will always be able
to restore all extended attributes. If it is not running
as root, it makes a best effort to set them. Using the -v
command line flag or the `verbose' command in interactive
mode will display all the extended attributes being set on
files (and at the end on directories) that are being restored.
It will note any extended attributes that could not be set.

The extended attributes are placed on the dump image immediately
following each file's data. Older versions of restore can work
with the newer dump images. Old versions of restore will
correctly restore the file data and then (silently) skip
over the extended attribute data and proceed to the next file.

This resolves PR 93085 which will be closed once the code
has been MFC'ed.

Note that this code will not compile until these header
files have been updated: <protocols/dumprestore.h> and
<sys/extattr.h>.

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

5941e412ca Add a caching option to dump. Use -C. Note that NetBSD has a caching option
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.

1c85e6a35d This commit adds basic support for the UFS2 filesystem. The UFS2
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).

or __pure2 where it wasn't already done, except in math.h where use
of __pure was mostly wrong.

019420a58f Andreas Klemm's patch set for dump(8), with some minor (cosmetic)
changes and one addition by me.

. Use reasonable defaults for the tape drive (/dev/rst0) instead of
  something we actually don't have.

. Add a summary line displaying the alapsed time and the total throughput.

. Replace "rmt" for the remote location of rmt(8) by "/etc/rmt", since this
  is the historical protocol, and relying on the $PATH causes a big pain.
  Make it adjustable via an environmental variable though.
