Virtual machine, Virtual server, Virtual disk, etc……

It doesn’t make much sense to me why someone would want to make their things "virtual" when basically that adds another layer to everything (which in most cases will make it run more slow).

What’s the purpose of Virtualization in the multiple cases above?

Thanks. Anything relevant and informative and my gift to you will be 10 pts!

I work for a small business that is interested in backing up their Exchange server to somewhere off-site. I recently configured our SQL databases to backup to Amazon’s S3, and was hoping to arrive at a similar solution for Exchange. The major problem however, is that our backup software (Backup Exec) I believe does only full backups, which would be too much data to upload to Online Storage. My question is:

Is there a way with Microsoft’s built-In NTBackup (or with Backup Exec) to do an incremental or differential backup of the MS-Exchange database? And, if not, is there a third-party software solution that does this efficiently?

On a Side-note, I was wondering if anyone knew how Mozy-Pro worked. It advertises that it can automatically back up Exchange, but it is simply a different Front-End for S3, and I’m not sure if there’s any difference in how it does the actual back-ups (full / transactional / differential?) .

I am running multiple screens from a single CPU through a VGA splitter, as all the screens have same display function with CPU. but i want to display different tasks on each of the screen. is it possible through VMWare Workstation or Virtualization. i need help about the hardware required and software for it. thanks
