What I would do is create a tarball of the files from backuppc
(BackupPC_tarCreate). Then pipe that into tar -tvf - it should list
every file, perms and owner/group.

  drwxr-xr-x rouilj/staff      0 2006-11-02 16:30 etc/logwatch/
  -rw-r--r-- rouilj/staff   1663 2009-07-06 14:36 etc/bashrc/bashrc

then pipe that into your favorite programming language (perl, awk,
sed) to transform it into a chmod compatible mode and file/directory
spec and apply it using chmod.

Note that this will only handle files in the backup, if there are
files with the wrong perms that are not in the backup (files newer
than the last backup or one of the ignored types of files such as
sockets) you will have to find/fix those manually.
