Not quite.

On most (all?) dump/ufsdump/xfsdump... you *CAN* backup a subdirectory,
but you *CAN'T* do an incremental of a subdirectory.

If you specify a subdirectory, Solaris ufsdump soundlessly forces
level=0 and ignores the record (u) flag,  Linux ext2 dump (I believe)
exits if level > 0 or the u flag is set.  This is what Bao is seeing
above.

Both behaviors are appropriately documented in the man pages.

I've got a weekly forced-full amanda config that does ufsdump on
several different subdirectories.  Works great, which is more
than I can say for the GNU tar attempt that preceeded it (yes,
I know GNU tar/Amanda/Solaris works great for everybody else
except me! :-)
