(Unless someone mentioned it and I missed it), I'm surprised no one has yet offered the standard reply: stand up a 2nd independent BackupPC server.
Because it's totally separate, you're free to configure it identically to the first one or if it's simply for DR, set up a different backup schedule (ie, weekly or monthly rather than daily) and retention period -- for example keeping only the last 2 backups rather than a long backup history... Easy to adjust to fit your available storage and business needs. Slightly more work up front, but easy to perform restores without depending on another server.
