Many on the list use rsync and rsnaphop to backup to an external hardware device. Based on personal experiences as a system admin I would regard this as an approach that has a couple of potential flaws. I would personally be a bit wary of relying completely on a USB based external hard drive as a sole place to backup data, backup to a network device or a caddy based device, with at least two independent locations would be much more preferable.
I have had the experience of hardware failure during a backup and lost both backup and source data as a consequence. As I was using removable media I could go back to an earlier backup, but with a single hard drive life might become the wrong kind of interesting. There are ways to mitigate the impact of hardware failure (e.g. RAID), but these do not cope with software related issues.
The option of buying more hard drives to cover this leads one to the scenario that one has more hard drive capacity to contain backup data than that actually been used to work with (a situation for a home based scenario that is faintly ridiculous). In a non-home environment the multiple location option this is obviously much more viable.
Yes, but it appears that is cheaper to have the capacity on external HDs on USB boxes, than to backup to DVDs, even if you have two or three disks. And they can be reused and rotated, similar to tapes. Plus, it is much faster! You don't have to be there changing DVDs. You just program it and leave.
If have looked at KDar/Dar and felt that these did not really work very well as a Tar/Star alternative. The Ghost/image based approach is good
I don't really like tar and similar things: they are easier to break, specially if compressed; and recovery from a large archive is slow and cumbersome. Pity rsync can not compress. You can use compressed DVDs, by the way. - -- Cheers, Carlos E.
