If you're backing up incrementally and your data doesn't change substantially (eg. OS backup), then 120GB will keep you going for ages. My 60GB disk backs up my whole system - OS, apps and data (total ~15GB) - with compressed level 0 dumps going back four months and is at only 55%. I'm not suggesting one can generalise too far based on my system, but it's a data point for a desktop/mail/web server[1]. The off-site issue is a tricky one with disks, but some DIY HSM can work in suitable cases. Perhaps more practical and cost-effective in the general case is to use the disk based storage instead of regular tape backup, using tape only for long term off-site archives.
