Personally, I'd rather use pg_dump. That way I'm guaranteed to have a
file which will work with a future version of PostgreSQL.
Why do you want to back up the file system instead of using pg_dump?
SIDE ISSUE: A possible benefit of using pg_dump instead of backing up the
file system: all parts of the database are excerised/explored; any bad parts of the file system will
be identified then.
