ddrescue can be handy for taking an image of a slightly defective disk to somewhere else, so that you can then experiment on the copy to recover things. > 2.

I think everything should be on RAID (and RAID0 doesn't count of course). OS, swap, data, everything. Disk failures happen, and they are a waste of time to have to deal with. RAID is of course NOT backup and not a sustitute (since RAID does nothing to protect against data corruption and user errors). > I am looking for something that doesn't crap out so completely.
