Professionally I have long liked IBMs TSM Storage Manager product with the Disaster Recovery option, but that is out of the price range for most.
I've been a TSM admin for years, so I admit I'm biased, but at scale I don't think there is much competition to TSM. The advantage of the progressive incremental backup (basically, incremental-forever w/o every doing a full) outweighs the licensing costs. What's going to kill TSM is if IBM ever fully rolls out the capacity-based licensing they've been threatening for years. I don't think their marketing folks realize that the big advantage of TSM is turning the cost of backups from storing multiple copies of a filesystem to tracking only the changes in those filesystems.
