Supress Extended Stored Procedure Output

Is there any way to suppress the output for extended stored procedures (xp_backup_database, xp_backup_log, etc)?

I do not want to see the following output:

SQL> Processed 2 pages for database '[REDACTED]', file '[REDACTED]' on file 1.
SQL> BACKUP LOG successfully processed 2 pages in 0.037 seconds (0.316 MB/sec).

Backup added as file number: [REDACTED]

Output File(s):

Native Size: 1.08 MB
Backup Size: 0.03 MB
CPU Seconds: 0.73
Environment: [REDACTED]

I consider the above to be debug information, I would like to be able to turn this off unless I specify otherwise, maybe through the use of a parameter?
