Looking at the edits made, I now realise that my grammar OCD dial doesn't go to 11 like some others! Now if anyone edits this comment to change the spelling of "realise" there will be war. And I prefer "Unix Sysadmin" :-)

comment Obsessive behaviors in system administrators
This is me! My wife's desktop is a "Modern Art Installation" of documents, links, folders, etc. I am so obsessive, 64bit versions of Vista / 7 annoy me with their additional C:\Program Files(x86) folders. Why? Why? Why? Put them all in C:\Program Files!

comment NetBackup Multiplexing for Oracle RMAN Backups
You would be surprised... often it is not the money, it is the projects, the budgets, the signoffs, the approved vendors list, the tendering process, etc. And backup isn't always the "sexiest" of project areas to be pushing...

comment NetBackup Multiplexing for Oracle RMAN Backups
All in good time :-) backing up 7TB oracle databases, requires a significant amount of staging space for this type of backup.

comment NetBackup Multiplexing for Oracle RMAN Backups
Thanks for the great explaination. I am aware of the shoe shining issue, and each single RMAN stream does about 20mb/s+ taking into account the SAN, the network, the hardware, etc. And, like you suggested, it looks like 3-4 times MPX might be the sweet point.

comment NetBackup Multiplexing for Oracle RMAN Backups
Hi Laura, What do you consider an acceptable speed for your LTO3 drives? I want to get them running at 80mb/s+ and my Oracle RMAN backups seem to be able to manage approx 20 mb/s per stream, which would imply an MPX of 4 or so. In the past, while I have hear the "restores take longer" comment, I have yet to meet a DBA who would restore to production, even a compromised production db. They much rather restore to another system, and work with the data, hence they are prepared to wait a little longer.
