Can some point me in the right direction or quickly summarize the
process of:
1. TSM backing up data to disk cache
2. Disk Cache hitting the high watermark (during backup) and ultimately
when it moves it to tape to reduce the watermark.  

Is that when you typically have co-location configured in order to move
data as expeditiously off of the disk cache to tape during a backup
window?

Sorry for this "very basic" question, but I'm fairly new with TSM.
