Solaris backup machine

Hi,

I have a server with Solaris 11 with a zpool raid to serve as a NAS. Every day in the morning I do an incremental snapshot of the zpool and send it to another local disk as a backup.

I would now like to build another small server to hold backups in a different place to prevent data loss due to e.g. fire, robery, aso. I would send there incremental backup snapshots once a week over internet.

Would you please help me choose HW for this backup machine? Follows a list of criteria:

  • the hw should be minimalistic (I will put it in a small metal box),
  • there should be no need for active cooling,
  • the performance of the system can be minimal (it will only be used to recieve and store backups),
  • it should support my 3TB SATA III HD (IntelliPower, WD30EZRX).

Thanks in advance!
