Re: Budget...how do I do it?
Fair enough, the figures i mentioned for the backup can be reduced quite considerably simply by going with cheap backup software like Backup Exec. and if you forgo virtual tape....

In later years you'll just be increasing capacity via additional storage shelves...a lot cheaper.
And in the unlikely event that you do have to go for a complete forklift upgrade three years from now you can sock it to the vendor by insisting they give you a significant discount on the newer model or you'll trade in what you've got with one of they're rivals.
One of the arts of budget planning is forecasting. Vendors have an annoying habit of providing a speed bump or whizz bang new features a few months after you've smaked down a wad of cash, but that is why what you buy should be backed up by research, inside info from suppliers on future product direction and include an element of future proofing - i.e can it be upgraded via simple firmware or inexpensive modular blades ?
One of the problems with the cheap and cheerful stuff is that it just won't scale...so while it's great for you're current requirements and you don't predict huge growth in the next 12-18 months fine, however if you're college expands or merges you'll be lumbered with something that's nothing more than an expensive bit of direct attached storage.
Similarly with a tape library, if you're backup requirements increase drastically and you're library can't accomadate an additional drive or 2 then you're CIO may not be too pleased with you're request for the additional cash for another bit of kit to solve a problem you both thought you'd dealt with 12 months ago. Hypothetically speaking.
