Prevention is good

Every now and then, people plan and go to great lengths figuring how to do data recovery before the actual data loss occurs.

What type of file system does the ix2 use with hard drives? For safety, I’d like to know how to recover data from the drives if the ix2 fails. I do not like the idea of relying on some hidden proprietary format that requires the ix2 to be able to retrieve my data in case of failure.

Anyone know how to read the disk formatted by the ix2 from a PC running any operating system?

There is no hidden proprietary format actually. Lenovo/Iomega uses run-of-the-mill Linux software and filesystems. However, the great confusion ensues little further in the discussion, mixing up filesystems with RAIDs, RAIDs with backup, single-disk RAID1 with a single partition, you name it.

Well, let’s spell it out

  1. Any NAS would use this-or-that form of RAID.
    1. Even if you have a single disk in a multi-bay NAS, it will have a single-disk RAID, most likely RAID1, to avoid changing data format if you add a second drive.
    2. Furthermore, if you have a single-bay NAS, it is still likely to have a single-disk RAID, to achieve compatibility across the entire model lineup (and specifically the ability to move the drive to the multi-bay model).
  2. Most modern NASes use one of the standard Linux filesystems, XFS, EXT3, EXT4, or BTRFS.
  3. If there is no damage to the data on disks, or the damage is minor, and assuming skilled operator, a properly configured Linux PC will read the data if all disks are connected at the same time.

But, the most important question here is: if one plans for data recovery before the actual loss, why do not have a backup instead of recovery?
