Hi,are you sure that the backuppc package is the culprit, rather than an apache update or some other, seemingly unrelated, system package that might have changed the setuid behavior?
IIUC, in your setup, the *interpreter* needs to be run as user backuppc, that is /usr/sbin/perl; did you have the setuid bit set on that file before the update?
I read the comment in the documentation about setuid emulation not being supported on many systems but it worked until the last backuppc update and perl has not been updated since september.
Probably you've seen those before - but just in case you didn't: Do the hints from the Arch wiki help?
https://wiki.archlinux.org/index.php/BackupPC#The_webserver_user_and_the_suid_problemI'm not using this setup, but I realize that one difference is user:group backuppc:http instead of backuppc:backuppc for BackupPC_Admin. Also, the description there suggests that if your approach worked before, it was a bug rather than a feature...
Best, Alex
