Amanda would need 5 drives, cuz it uses a

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
nightly backup was over 40 Gigs on a 14 day dumpcycle.
... I would buy three mobile racks:

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 put my bare drives in these cases:

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?
IDK, old house wiring, which is now a 240 volt ct branch of the new 200
amp box. I rarely tear
out a wall just to see the wiring. The house is a 1969-1970 National
prefab, and from looking at it
for 34 years now, the NEC as it existed then, wasn't well followed. The
living room has no
overhead lighting at all, and only two wall switched outlets, both on
outside walls. When I decided
to use this small childs bedroom as a den for my computing, I did run
down the circuit for one
on its inside wall sockets, and soldered everything all the way back to
the pushmatics, then put a huge surge absorbing pluggin strip into that
plug. And a 1500wa ups, so both holes of that duplex are loaded. Almost
everything in this room but the overhead lights and some x10 stuff runs
on that duplex.,
How did plugging the computer and the monitor into two different
circuits affect the outcome of a lightning strike?
Probably on opposite phases. But thats a SWAG at best. Until that, after
the new service in 2008, I'd not had any lightning damages despite the
pole with my can on it being struck multiple times. I use wireless
keyboards and mice as I did once years ago take it in the fingers and
lost a keyboard with wired stuff. Theory is that if my can gets hit, and
the whole room bounces half a million volts, its all bouncing in unison
and as long as it doesn't
jump an air gap, its all fine. Before 2008 and back in telco wiring, I
lost a modem everytime we had a heavy
dew. But I sent a gooby to vz & their 75 yo cable they couldn't make
work a decade back in favor of the local cable for phone and net. Almost
zero problems since, lost the phone for 2 days in the aftermath of a direcho
that did $18,000 in damages. For a while after that, I had the only tree
that survived in the path of that
direcho. 4, 45 foot pines in my front yard didn't but that pin oak did.
That was in 2010.
