Linux's best backup option is probably dd.
Suse Linux does appears to have some kind of system restoration feature. I generally don't trust system restore. No matter what OS. If theres a flaw in the operating system that causes a need for a system restore. Whos to say the system restore feature itself won't fail? Theres nothing quite like a good ol clone drive backed up to the internet somewhere. Or atleast a file level backup burned to cdroms. Make sure you copy those copies too. And put them in a safe somewhere. A fireproof case at that. Then burn a third copy(encrypted if need be) and give it to friend. Make him promise he'll won't lose it or do anything to it. Tell him to put on top of his kitchen cupboard. Witness him do this. The reason why I say this is people generally don't use the top of their kitchen cupboards(atleast in the houses, I've been in) and they're not often changed. Especially if its a guy.
And if you think you have an interesting enough harddrive you can even put it on P2P, or bit torrent. People will swarm it and back it up for no particular reason. I swear.
