Subject:        SUBFILE Techonical Details?

Is there anywhere that I can find the technical details on how SUBFILE
works? For example..
what does it use the local cache for? - if I have 20GB of backup data,
how
does it use the 10MB cache area?
what if I delete the local cache?
does TSM always backup the differences, or is it smart enough to say this
difference file is 50% (for example) of the original so I'll back it all
up!
does it do a full backup every now again anyway?
should compression and subfile be used together?

It would be really nice to see all these questions and more answered in one
paper...

Regards
