Turn on auto-backups of HFiles on the specified table.
<p>
When HFiles would be deleted from the hfile archive, they are instead preserved.
@param table name of the table for which to preserve hfiles.
@return <tt>this</tt> for chaining.
@throws KeeperException if we can't reach zookeeper to update the hfile cleaner.
