    • Raspberry NAS for TimeMachine AND Storage

      Hi all,
      i'm completly new to this topic and i would like to setup my own NAS at home.

      I have a Raspberry 3+ with 2 disk (4TB+4TB) and i would like to have the two mirrored as i don't need any versioning.
      It is possible with OMV to have one disk (4TB) partitioned 1.5TB for TimeMachine and 2.5TB for general storage and this full disk mirrored to the other one (just in case one disk dies)?

      Thanks in advance.
      Fede :)

      By mirrored, I hope you mean rsync because we highly recommend against using raid on an RPi or usb disks.

      You don't need partitions for this. Create two shared folders on each disk. Then create to rsync (or rsnapshot) jobs to sync the source disk to the destination disk.

    • By "mirroring" i mean a full copy with all my files so in the case that the primary breaks i can easily replace it with another disk and have all my stuff back and running again. I don't care if i have to do some work when something breaks, i just want a FULL exact copy of the original drive. And yes, they are USB drives.
      Is rsync what i need or raid 1?

      Are you sure about this? If you make a mistake on one file, this error will mirrored to the second drive. No chance to recover the previous version.
      If you delete a file, it will be also deleted on the mirror (depending on the settings).

      rsync is what you need. While you can tell it to less than a full copy, it can easily copy every file on the drive. And since you are using an RPi, you don't want raid.

      While timemachine does do versioning, your mac has access to the share. That potentially means a virus (thinking crypto virus and yes, i know you have a mac) could corrupt the entire backup meaning your timemachine versioning is worthless. If you were using rsnapshot to sync the main drive to a second drive, you would have a share not accessible to any system on your network that had many different versions saving the day. Just my opinion as someone who has dealt with quite a few people hit by crypto virus badly using Windows versioned backup to a share on a NAS.
