Now that someone has started this thread :)
Are there any other "industrial strength" backup solutions like arkeia out
there?
I got my quote for arkeia today, and it was 7 grand. No way on my budget.
Amanda looks good, but not being able to append to tapes killed it for me.
Anything else in that catagory? Commercial, open, whatever.
