From this page:

http://www.postgresql.org/docs/current/interactive/continuous-archiving.html

There is this:

| Be certain that your backup dump includes all of the files under
| the database cluster directory (e.g., /usr/local/pgsql/data). If
| you are using tablespaces that do not reside underneath this
| directory, be careful to include them as well (and be sure that
| your backup dump archives symbolic links as links, otherwise the
| restore will corrupt your tablespaces).

You might want to search that page for the other mentions of
"tablespace" to find the descriptions of when to make a backup, how
to restore, and caveats.
