I use it whenever I need to read [often somebody's else BD] or write big chunk of data onto something [very convenient dimentions if you need to send it elsewhere]. I used it to make image of Windows system my laptop came with (after I added all I may need on Windows), so I can restore my laptop from that BD. I doubt I will ever need that, as I wiped the system in favor of FreeBSD (which is single system on my laptop). I do not use BDs for backups though, I backup everything, including laptops to bacula backup server. Just my $0.02.
