Thanks Squid.
I agree the USB is nice if you make sure all your logs are write to tempfs (RAM drive). The problem is that usb drives are not made to last very long or for an enterprise environment. Most of my equipment is enterprise level (Xeon with ECC memory and enterprise drives.) You know how us IT guys are, always looking for a way to prevent a failures. The whole reason I was moving from 3TB to 8TB drives was that SMART had shown some read/write errors close to the threshold levels (especially since the drives were already over 5 years old)
I'll setup up a backup schedule to back up my config directory to a un-array drive. (Mounting it with unassigned devices plug-in).
As before, I'm more worried about my data on the array than anything else. Was going to build another NAS to backup to. Wished Amazon was keeping unlimited.
Thanks for the input.
