This one is kind of obvious, but if you are moving to a different
server or installation it is possible for backuppc to have a different
numeric uid than on the host that created the files. The chown that
Adam suggests would fix it if that is the case. Also, I believe
different packaged systems use different ways to make the web
interface run as the backuppc user. You may need the perl-suid
package or maybe httpd-suexec. And the filesystem mount probably has
to allow suid - but that should be the default.
