  "cp -a" preserves hardlinks in the version *I* have.

$ rpm -qf `which cp`
coreutils-4.5.3-26
$ mkdir testdir
$ cd testdir
$ mkdir source
$ cd source
$ touch foo
$ ln foo bar
$ cat bar
$ echo hello > foo
$ cat bar
hello
$ ..
$ mkdir target
$ cp -a source target/
$ cd target/source
$ ls -l
total 8
-rw-r--r--    2 bscott users           6 Nov 15 17:14 bar
-rw-r--r--    2 bscott users           6 Nov 15 17:14 foo
$ cat foo
hello
$ cat bar
hello
$ echo goodbye > foo
$ cat bar
goodbye
$

  All that being said, I never use hard links myself, so I had to go
and double-check this before I was sure.  One more example why real
backups are important... :)
