David, On the backup mirror you could install, but not run, BackupPC. That way you'll have access to the command-line utilities, but no backups will run. If your primary backup server fails, it's probably best to not write new backups to the backup server.
It's pretty easy to browse client backups with BackupPC_ls and to create tarballs with BackupPC_tarCreate or zip files with BackupPC_zipCreate. There's also a community-developed Fuse file system for BackupPC, which provides read-only access of backups via a mountable file system. Unfortunately fuse doesn't allow some specific things to be represented accurately, which if I recall correctly are hardlinks and xattrs.
