• also what drives are you using?

    For info I use Western Digital Red which I would strongly recommend. The current set in my NAS have been running for 3+ years. The previous set which I sold when I upgraded my NAS had been running for 6 years continuously.

  • I’m using wd reds.
    Backing up the raid hasn’t entered my thoughts. I’m focusing on getting it up and running and hopefully the raid 10 configuration means I can swap out drives when they fall over, keeping the system up and running.

    Will look into cloud based storage or cheaper external drives as an alternative.

    Cool.

    The thing to remember is that RAID is a solution for availability, you can't treat it like a backup. If it is actually being used as a backup for another drive then don't use Raid 10, it's wasteful.
    Yes Raid 10 can hot-swap and Raid 1, 5, 6 and 10 offer drive redundancy but how will you recover your data if the cluster gets corrupted or the physical server goes kaput?
