Here is one: something bad happens with your FS so you need to fsck, rebuild-tree (or what the corresponding thing for reiser4 is) or something like this. Having important files duplicated improves the chance that at least one copy is still intact afterwards as depending on the grade of corruption rebuilt fs may show the same files but contents may differ. (verifying which copy is OK is not in the scope of this writing) Yes, having backups is better but that wouldn't help if it's your laptop, the backups are 2000 miles away in your office and you have only some Linux Boot CD?! ;-) I know, that doesn't happen often but I've had similar situations. As I've allways managed to help me somehow missing this feature wouldn't make me cry but I would probably use it. Just my two cents. > But then again, that should not hinder anyone :-)
