  • RAID 1 is mirroring. If you accidentally delete a file, or it becomes corrupt (for reasons other than drive failure), RAID 1 will faithfully replicate that delete/corruption to both drives. RAID 1 only protects you from drive failure.

    Implement backups before RAID. If you have an extra drive, use it for backups first.

    There is only one case when it’s smart to use RAID on a machine with no backups, and that’s RAID 0 on a read-only server where the data is being replicated in from somewhere else. All other RAID levels only protect against drive failure, and not against the far more common causes of data loss: user- or application-caused data corruption.




  • Are compatibility issues common with ZigBee? I went down there Z-Wave path years ago, somewhat arbitrarily. I’ve never checked devices for compatibility, not encountered any that didn’t work. As of today, I have 58 z-wave devices connected to HA.

    My controller supports ZigBee, and the previous owner left some devices in the house (window sensors, mostly), and I’ve tried unsuccessfully to pair them; I haven’t yet really spent any time trying to troubleshoot, but I’ve been contemplating adding ZigBee to the mix because they’re sometimes cheaper. I really don’t want to have to struggle with compatibility, though. It’s just one more thing to have to fuss with.
