FYI to those of you using Disk Staging Storage Units,
5.1mp4 includes a change that you're sure to notice:

(from the "DESCRIPTION OF PROBLEMS FIXED" text)

========
Description: 
Disk staging only submits one duplication job at a time so it was unable 
to make use of idle tape drives. 

Additional Notes: 
Up to four bpduplicate jobs are submitted at a time. The duplication jobs 
contain images grouped into jobs of 25 Gigabytes. By creating files named 
MAX_STAGING_JOBS and STAGING_JOB_KB_LIMIT in the NetBackup directory on a 
media server, these defaults can be adjusted as needed. For the 
STAGING_JOB_KB_LIMIT, the value is in kilobytes and the default is 26214400 
(25 gigabytes). A smaller value causes more jobs to be submitted, but 
there will only be MAX_STAGING_JOBS running at a time. 
========

Note that the reference to "a media server" is a typo - it should
instead say "the master server" instead.
