Optmizing tape media usage for CommVault Simpana 9

Hello,
We have CommVault Simpana 9.0.0 build 84 currently installed and configured on our backup server that is equipped with both a magnetic array and a tape library. It may be a newbie question, but it seems as if the system refuses to copy to tape and append one job after another to the same tape. Because of the current configuration, we now have multiple tapes with data ranging from a couple gigabytes to over a terabyte, but it is rare if ever at all that the system actually fills up a tape. I found some options under the Media tab for the copy properties of the various different Copy to Tape storage policies that I believe should fix my issue, but I am wondering what the preferred or recommended options and numbers are for the streams and multiplexing factor. I also check off that I want to Write a different library compared to the source copy. It would be ever so greatly appreciated if someone with a little more experience could advise me on these settings if they are in fact the settings that will fix my seemingly prematurely limited tape storage issue. I plan to try creating a new storage policy if for some reason these changes do not get the job done.
Thanks!

To answer my own question, this was only part of the issue. I have since then reconfigured our storage policies and combined them in to one with an assortment of schedules that will fit our needs.

To answer my questions about the CommVault storing data onto multiple tapes, Dwight was definitly correct in the fact that the System can not put multiple storage policies onto one tape with the only exception being that the system generated DR policy can be configured to be included with a storage policy using its control panel. This resolved the issue of us having tapes going off site once a week with only 20Gb of DR data on them.

The only issue that this poses is that in the event of a total system failure and DR situation, one must use the TapeToolGUI and CommserveDisasterRecoveryGUI to locate the correct tape with your DR database and then use the DR tool to recover the database.

Hopefully this helps someone else!
