Rsync should be fine.  And searching for a specific entry in a directory should 
be way faster than looking at every entry to see if it needs copying.  Right?

Doesn't rsync allow you to give a list of files rather than a list of 
directories?

   --include-from=FILE  option looks like it should do the trick.

But it still has to scan the directory to find the listed files. If the
directory is large, this might be timeconsuming.  The only way around
that is to create hard links to the files you want to backup in another
directory, or find a way to split up your directory into smaller
directories.  Hardlinks require the inode to stay the same (a delete
followed by create with same name cannot be allowed as this results in a
different inode), but symlinks still have to go through the original
directory, so they are no help.

Hope that helps.
