Scheduled backup email has minor error

So, using the scheduled backup feature (an admin for a virtual server is). The emailed report ends as follows:

2 servers backed up successfully, 0 had errors.

Backup is complete. Final size was 0 bytes. Total backup time was 00 minutes, 04 seconds.

Well, the final size was not 0 bytes needless to say!
