A second matching mass-storage device is normally such cheap insurance that, on any host more substantive than a laptop, I would say insist on RAID1ing any directory trees you care about, and just RAID1ing everything if you can reasonably do so.
RAID-1 or ZFS with copies=2 on a laptop will save you from many situations of data loss or corruption. I have my clients give me SATA disks that have bad sectors and are therefore unsuitable for use in servers. I make them BTRFS RAID-1 and they work fine for me as backup disks. Most such disks only ever have about 50 bad sectors and RAID-1 covers that nicely. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
