Hello list, I was wondering, from a point of view of data safety, if there is any difference between using dup or making a raid1 from two partitions in the same disk. This is thinking on having some protection against the typical aging HDD that starts to have bad sectors. On a related note, I see this caveat about dup in the manpage: "For example, a SSD drive can remap the blocks internally to a single copy thus deduplicating them. This negates the purpose of increased redunancy (sic) and just wastes space" SSDs failure modes are different (more an all or nothing thing, I'm told) so it wouldn't apply to the use case above, but I'm curious for curiosity's sake if there would be any difference too. Thanks, Alex. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
