Amanda would need 5 drives, cuz it uses a
dedicated holding disk and completes the DLE to it, before moving the completed DLE
to the vtape.

I now have added 2 rock64's and killed one old Dell with a lightning strike since.

Lightning strikes getting into residential electrical systems is extremely dangerous.

You are preaching to the choir. I am a Certified Electronics Technician.

4 @ 1 TB HDD RAID10 seems like overkill for 228 GB of backup data.

I'm just getting re-started. Before the seagate experiment killed everything, my typical

I already have a 4 bay version of that, half full of SSD's now at 2 per 3.5" bay.


Okay. 2 @ 1 TB RAID1 in the server and individual 1 TB drives for off-site would work for 560 GB.

I redid the service in 2008, brought it all up to NEC specs, but the computer and the monitor were
plugged into two different circuits. Jury rigged, fixed now.


Were the two different circuits on the same phase, or opposite phases?


How did plugging the computer and the monitor into two different circuits affect the outcome of a lightning strike?
