Most system users do have a home, and backuppc certainly will. On Ubuntu 8.04 
and 10.04, it is /var/lib/backuppc.

root@backup1:~# grep backuppc /etc/passwd
backuppc:x:106:116:BackupPC,,,:/var/lib/backuppc:/bin/sh

Do make sure this user has a shell. /bin/sh works for me. Then su to the user 
and generate keys, or copy a trusted key to the user.
