These three can probably be combined:
- Limited to specific filesystems, e.g. "dump" for ext2/3 on Linux and
UFS on *BSD, "ufsdump" for UFS on Solaris, xfsdump for XFS on Irix and
Linux, vdump for AdvFs on Tru64.

Are you sure? Pretend you're on a system that doesn't have GNU tar.
Now pretend you want to back up a file system with really long paths, lots
of files with holes in them, and a batch of named pipes. Traditional tar
implementations stink for all of these.
Dump also has a cool interactive restore feature. Too bad it's deprecated
for 2.4 and beyond.
