there's a video coming soon a video about the catastrophic failure of the
rid array on our 20 terb SSD server code
name wanck but before we do that video
why don't we take a moment to introduce to you the newest member of the lonus
Media Group server family the one I was literally in the process of backing W up
to when the failure happened meet Clover
server
the Logitech g303 features a lightweight design an advanced Optical sensor with
Delta zero technology for precise tracking and RGB lighting to match your
setup check out the link in the video description to learn more so I think a
video about Clover server has to start with the differences between backup and
redundancy redundancy protects from a hardware failure to an extent but not
from accidental deletion encryption by
ransomware vandalism or what I would call catastrophic Hardware failure the
benefit of redundancy is that it's real time a single drive failure in a raid
five array for example would allow the business to keep operating completely
normally and would result in zero lost data as long as it could be offloaded or
the raate array could be rebuilt with backup you'll only get back whatever was
in your last periodic backup so Clover
server wouldn't have prevented any data
loss from the catastrophic raid failure that recently occurred with wanik server
one of the raid cards crapped all over the inside of its pants took its pants
off and started swinging them around what it would have prevented was
projects that have already been shot weeks ago but not yet edited like this
video that we had planned for Channel Super Fun from being entirely lost so
let's take a look at the hardware Clover server is using a quad core xon
processor on an ASUS p9d M Server Motherboard with 32 gigs of Kingston ECC
DDR3 memory to give me the best possible stability of course the Redundant power
supply from istar USA helps with that and the toolless case well okay that's
just for convenience but the hot swappable Drive bays are really really
nice ignore that RAID controller you see in this footage that's going to be
replaced with an LSI HBA and I've also added a 10 GB network card to handle the
workload alterations that I've made since I built this box for storage I've
gone with eight of seagate's 8 tbte Enterprise capacity drives these suckers
do in the neighborhood of 200 megabytes per second and have a rated meantime
between failure of two million hours
however whatever their reliability might be in this particular application where
the intent is to achieve reasonable speed but more importantly
extraordinarily safe backup remember this will be the only copy of some data
in the event of wanic pooping itself again I'll be giving up a lot of my
capacity to the redundancy Gods as well as the speed
Gods so like most of our servers these
days the software side of things starts with a fresh install of limex unraid
which by the way they have sponsored projects of but this isn't one of them
so we'll be setting up two of our 8 TB drives in what is effectively an 8 tbte
raid one array configuration and then we'll take the other six in a butter FS
RAID 10 for 24 tab of redundant storage
the plan for the 8 tbte array is pretty
straightforward I'm going to set up a Windows Server 2012 R2 Essentials VM a
pretty simple process since I don't have to do any video card pass through or
anything like that if you want to learn more though about unraid VM setup you
can check out our two Gamers 1 CPU video here I chose Essentials 2012 R2 because
even though it's quite expensive at about $500 for a license the way it
handles incremental backup and restore functionality for up to 25 computers is
really slick and seamless not to mention that if we ever wanted to move to a
domain setup it includes active directory domain Services although for
now we're still using a work group so I did have to use this simple workaround
to enable the nightly backup functionality without requiring the PCS
to join a domain from there you download and set up the connector software and uh
this is basically a quick look at the dashboard that allows you to set the
schedule for nightly backups how long you want to keep them for and change the
storage destination to the secondary V disk that I created for those backups so
7 tabt should be lots for our SSD equipped workstations here in the office
all right then lonus but what about that 24 terab of RAID 10 storage on this
machine great question I've got two plans for that number one is to use
Beyond Compare a great piece of software that compares the structure of two
directories and allows you to set up all kinds of rules for copying One Way
copying the other way or synchronizing between them and I'm going to use that
to do incremental synchronizations so this is kind of somewhere between
redundancy and backup since I plan to run them every 30 minutes or so and I'm
setting up the relationship so that a deleted file on wanic will be removed on
the Clover server side as well then
every night I will set up a backup operation from Clover to the Vault where
files deleted from wanic and therefore Clover server will not be removed from
the Vault so we have somewhere to turn to if we accidentally delete something
major so those operations can both be scheduled simply with Windows Task
Manager uh super handy and then a monthly or whenever we feel like it
cleansing of the deleted stuff on the Vault can be done using Beyond Compare
as well now this isn't a perfect solution but butter FS snapshotting is
still a ways out so it'll have to do for now and we've got lots of space on the
Vault so I'm not too worried about it anyway that still only accounts for
about another 20 terabytes of the space on Clover so we've got 5 terabytes of
wiggle room for that plan number two I'm going to be leveraging my ceon to use
that extra space as an off-site backup for my Nas at home using crash plan
normally I'd actually have to run crash plan from within a Windows environment
or at least something with a goey but the benefit of using Docker within
unraid to do it I do plan to do a full video about Docker containers and why
they're awesome in the future is that if Windows borks up crash plans backing up
of key files there's not enough leftover space for my whole home array will be
uninterrupted normally setting up crash plan on a
headless machine is kind of a nightmare but unraid way is a bit more elegant so
in summary there's three main points for this video One backups are important two
create two backups of something that's important during a data migration and
three more details on the catastrophic raid failure to come speaking of
catastrophic have you ever been in a situation where you're like I want to
watch American net but I am not American
or I am American and I'm not an America well tunnel bear is the easy to
ous VPN app for that and all kinds of stuff tunnel bear lets you tunnel to 16
different countries allowing you to browse the internet and use online
services as if you are in a different country they've got apps for iOS Android
PC and mac and they've also got a Chrome extension when you pick a country and
turn tunnel bear on two things happen your connection gets encrypted with AES
256bit encryption and your public IP address gets switched so that you show
up as if you are in that other country and they' fixed all the annoying stuff
that's frustrating about vpns while offering
500 megabytes of data for free to try it
out with no credit card required then if you want to upgrade to unlimited data
you can save 10% by going to Tunnel bear.com LT which is linked in the video
