    • My project - NAS in RAID 1 - suggestions wanted

      Hi,

      I want to show you my project so you can tell me what you think about it
      and if I'm forgetting or wronging something.

      I have a raspberry one with OMV installed to create a NAS.
      Two hd 2,5" in RAID 1 (always powered on) plugged in an external usb hub with external power,
      the hub plugged in the raspberry. Here I want the maximum security level.
      The RAID content is for important files (photo, ecc...).
      An hd is bigger than the other one (500 vs 320 GB), the RAID
      partition will be 320 GB, obviously.

      The remaining space will be used for low-important data, and
      maybe used to be accesible to other user with a password
      (or other ways ?).

      I want to use a third HD, and old 3,5 ", to manually backup the
      RAID content, and be manually powered on.

      This is my project, do you think it is feasible, do you notice
      some critical issue ?
      Do the RAID works with logical partitions too, or only with whole physical HD ?
      How can I simply manage the manual backup in the third HD ?

      Any suggestion will be accepted, thank you !
    • You would have to create the raid array on something other than OMV. OMV doesn't use partitions for raid arrays.

      I would put your files on the larger drive and then setup rsnapshot to sync just the important files to the smaller drive.

      You could use the usb backup plugin to sync files to the third drive.

      What do you mean with "Create the raid array" ?
      The raid selection in the menu is for what ? Now I just have 1 hd, then I cannot try it.

      I installed Rsnapshot and USB backup plugin, I can't see the difference between them.
      It seems that both allow you to select a folder to backup and a target folder where to write it.

      Are you saying that I have to create the partition before plug the HD to the rasp ?
      Do you know what can I use other than OMV ?

      I said you needed to use something else because your idea requires partitions with your raid array and OMV doesn't use them. If you were using a standard raid setup, the raid menu works fine.

      rsnapshot creates multiple backups (hourly, daily, weekly, monthly, yearly) on a schedule.
      usbbackup creates backup to the usb disk when you plug it in.

      Only partitions in a raid array which is non-standard for OMV since it doesn't use partitions in a raid array. If you are creating standard partitions that are not part of a raid array, then OMV web interface works great.

      OMV is the best solution out there. That is why I use it.
