RAID is meant only for uptime, backup is something else, see: http://taobackup.com/. > You can try Btrfs raid1 or mdadm raid1. Mostly agreed with btrfs[1] (though ZFS is probably better, if you are fine with out-of-tree kernel modules[2]). On the other hand mdadm can't detect silent corruption. In case a flaky drive (like the one discussed here) returns corrupted data claiming it is good mdadm RAID can't detect this, and in case it detects it, it has no way to determine which data is good. Worst case it might even overwrite the good data with the bad one (because the bad data appears to be newer). > Whatever you choose, try not to use this drive without any > backup, as you are not sure yet if damage are not progressing. Yep.
