Q1 What is my Current Backup Solution?
A1: On my NAS, I currently have it configured to run daily incremental backups, meaning it will only backup data that has been changed since the last successful backup, it holds all data revisions for 30 days, then deletes the oldest. If I deleted a file 26 days ago, I can go through the backup revisions and restore the file from the backup that occurred 26 days ago. My backups are stored on a different HDD than my data so if a drive fails, I will still have access to either my data or my 30 days of backup revisions, which I can then use to restore from. Currently, I do not use RAID, as such I don’t have redundancy for my data, but I do have a backup. I'm thinking of overhauling my backup systems to incorporate a RAID 5 array (for redundancy) and an incremental backup system (for backup) to an external location - this will then give me both redundancy and backup for my data.
Q2: Is Windows RAID better than BIOS RAID?
A2: No, Windows RAID it’s configured within Windows (internal to the OS installation), if anything were to happen to the windows installation, the RAID array would need to be rebuilt, and you may lose data. If you wanted to reinstall windows, you would need to back up the data in the RAID, reinstall windows, reconfigure the RAID then transfer the data back
A2: If you set up the RAID in the BIOS (external to the OS installation), when you install Windows (or other OS) onto that RAID array it will see the RAID array as one big drive. Windows won’t even know it’s installed on a RAID array, meaning, no matter what happened to your windows installation, the RAID won’t be jeopardised. You can reinstall windows as many times as you want (but make sure to always back up your data before reinstalling)
Q3: How will I know when a drive fails in the RAID array (degrades)?
A3: I cannot confirm this as it's never happened to me, but I would expect Windows to alert of a drive failure through Windows notifications. To rebuild the array, you would be expected to power down the system, replace the drive with a working one of equal capacity, power on the system and rebuild the array from within windows (I'm not sure how this is done, as Windows keeps changing the way disks are managed)
Notes:
- If HDD/SSD is equal to or smaller than 2TB, then select "MBR" *
- If HDD/SSD is larger than 2TB, then select "GPT"
- *If your HDD/SSD is smaller 2TB but you want more than 4 partitions, select "GPT", because MBR only supports up to 4 partitions.
Learning from my recent HDD corruption which meant I needed to send off to get it professionally recovered, I have bought 2x Western Digital Red drives that I am going to set up in RAID 1.
I chose WD Red drives as they are manufactured for use in NAS storage systems which are usually left on 24/7, thus these drives “should” be more durable when compared to the lines that WD manufacture.
RAID 1 is a RAID configuration that mirrors two or more drives, meaning the same data will be written and stored on each of the drives configured in RAID 1 configuration. This means that if one drive fails, you still have the other drive(s) which contain the same data, so you haven’t lost your data, just the failed storage drive which you can replace.

samone need LOONGER videos lol
I have never performed a RAID configuration of any kind, I was scared when I was assigned this. I found your video quickly and it could not have been smoother or quicker to do. GREAT instruction and quick seamless delivery in 13:00 mins. LOVE IT! Thanks
THANK YOU! Frazer, you certainly are an amazing instructor and speaker! The whole story: what not to do, what to do, its limitations and why.
Thank you Frazer, I was trying to set up a Raid 1 on my SATA drives, you are correct it is a major hassle. Thanks again.
RE: RAID 1. Assuming when the HDD fails it doesn't cake out the other drive. That is HDD1 fails, corrupts data that is then replicated across HDD2. The way around this is to back-up to another drive regularly and used a file system such as ZFS or BTRFS (these file systems generate a hash of each file to determine which is the 'correct' file). I never fully trust RAID for that reason. Instead I use ZFS to pool hard drives together and duplicate, snapshot and checksum files in addition to external HDD and cloud.
I'm pretty sure you can RAID 1 drives of different capacities, however, your storage capacity will be limited by the size of the smaller drive.
Hi
Thanks for sharing.
You have added two 2 TB drives, in Raid1 . You have added this for keeping the data availability in mind ( and not for backup). This is very clear.
Your first hard drive has the OS and other apps and contents of your choice.
I have a query.
I wanted to use your approach, including OS, in the below manner. Please, inform whether the approach is OK or recommend an alternative.
Step -1.:. I take the image of the hard disk that has the OS and some apps in it.
Step - 2: Using your procedure , setup the Raid1 .
Step-3: Restore using Acronis, the backup taken earlier on to the Raid 1 hard disk
My Query:
Can we remove the first hard disk now.
Will the mirrored hard drives in Raid 1 , can we expect it to come up , as it has the OS.
Once this stage is through, the leftover space available is for data.
Now, we have OS plus Data, which makes it even more reliable.
My doubt....In your video, you are showing it for data. My interest, is how to include OS as well. My OS is Win7.
Appreciate your help and advice.

Capeless hero. Thank you.
Thanks for the info.
excellent video Frazer, exactly what i was looking for - thanks
Thank you for the video. Also, love the lion picture lol. Why did you remove the lock from the door behind you halfway through the video hahahahha
How will i know if one of the drives dies?
Have a PC with 4 HDD's. I bought a QNAP enclosure and 4 big drives hoping that I could simply use a combo of i internal PC drive and one drive in the enclosure as a RAID in a DAS config. Spent $1,000 only to find out all I could do was use windows "copy" to copy each internal drive to each of the 4 drives in the enclosure. Data transfer was agonizingly slow and I have $1,000 invested in this setup. Could have accomplished the same thing and cheaper with external backup drives and no enclosure. Wish I had watched your video before wasting the $$$
No you did not put the command to copy in the description
Thank you much appreciated!!!
Thanks for the vid! Very helpful :)
raid mirror works when os drive replaced and windows install?
When you create a raid 1 array do you have to use nas hdd (like WD Red) or just any 2 similar hdd or ssd drives?
Thank you and I gave you a thumbs up for your page and the answer, keep up the good work, you look and sound very knowledgeable.
Well. The correct answer is "you have to use drives that supports working in RAID. Like RED or Purple..". And here is why.
Actually, when everything works, it doesn't matter. And that is not the purpose of creating RAID-1 or 5, right? You create it to have stable data storage. But when one drive starts to have problems in reading one sector (even if it's not because of bad sector, but because of some temporary vibration or so), normal HDDs don't have reasonable limit of time trying to re-read sector. So usual HDD (like WD Blue) will be trying to read it again and again for 10-15 seconds or so. And there is a problem. When raid controller sees that one device experiences issues, there is about 3 seconds to skip the data, read if from another drive, and go further. That is the logic RAID controller expects from hard drives connected to him. But when HDDs don't respect it (and normal home Hdds know nothing about such a respect), RAID controller will just kick such a device from raid automatically. Because for him is means that device is "totally down". So as soon as one of your hdds has some sporadical issue in reading one cluster, your RAID becomes dramatically unstable loosing one or another drive from time to time.
Very good. So, the Windows OS is not copied to the new Disk in RAID 1? Thanks.
Very good teacher , I like your way , thank you
Very helpful, thank you
HI, can you explain the erecovery process in case of failure of one drive? and how to setup another new disk with the survived one again in raid
So Usefull! Thanks bro
Question - once you've created your RAID 1 array, can you share it on your network the same way you would a regular stand-alone drive?
@@FrazerForbes1 Thank You....I have been Googling that question for weeks now and could never find a straight answer.
sounds great, until my mirrored volume is greyed out.
Thank you!
Can you back up NAS to NAS on the NAS? As an example, in a 4 bay with 4 8tb drives, can you set up 2 RAID 1 arrays and back The first RAID 1 arrays to the second RAID 1 arrays.
I have a Crucial 240 GB SSD for operating system and WD Blue 1T and I want to get another WD Blue 1T, so can I creat a raid 0 drive using 2 WD Blue tera for each one while AHCI enabled in bios... I just need more space for games
Hi, great informative video about setting up RAID 1. Question: if my Disk 0 becomes defective, can i use the Disk 1 as the drive to boot up to windows to operate my system again? thanks
Hi i have 2 x 1TB HDD with Hardware RAID 1 and I need to install dual boot windows and Linux centos 7.4. what is the best solution for this? thank
Question Frazer, If I want to mirror my current OS (Win 7) with a new sata the same size do i just plug in the second disk and follow your instructions?
What should I do if i get a "there is not enough space available on the disk(s) to complete this operation"? Thanks in advance
Hello. I have a problem. on a computer unit I have two hdd 6-terabyte . I have configured raid 1 and installed windows 10 . But I only have a 2 tera partition. On 3.5 tera can not create another partition. Help.
When the drive fails what do you do to add one back into the array?
Just replace the faulty drive
Hi Frazer Forbes, could you please advise how do we know if one of the drive fails? Also, how do we replace the failed drive and mirror data from the other one. Thanks in advance.
Video helped, thanks!
Can you make a Raid mirror that includes the existing OS?
Do I presume that the operating system has to be on a separate third disc?
Good stuff mate : )
Thank you bro :)
is this setup ideal for graphic designers when they want to edit heavy files in realtime ?
WORKS PERFECT!
Hi there fella, How do I raid 1 disk 0 and disk 1?
What HDD do you use for the mirroring, normal desktop HDD or NAS HDD?
I believe it's RAID0 instead of RAID1, because you can use 50% of Total storage in RAID1.
If raid 1 or mirrored raid is not meant for backup, then why to do such raid at all. Isnt that a waste of a drive
Now days, yes. For most cases
Thanks man, grazie 😎
So I want to do a Raid 1 on my hard drives so it well be like a "synced backup", do you recommend that or do you have another way to have a constant drive that automatically backed up your data, Thank you and VERY easy guide to follow
I would think RAID 1 is your synced backup.
all cool and all ... but this is NOT raid .. raid u have to set in BIOS on supported motherboards and switch sata controller from AHCI to RAID .. so without doing so... disks are still operating in AHCI and this is just dynamic mirrored disk without rebuilding option if one of them fails
After you have setup the raid 1 with two drives, and have places data on it, have you tried to remove the 2nd drive to see if you can still access the data on the remaining drive? I'm wondering how to find out the behavior of the raid 1 system when one of the drives fails.
@@FrazerForbes1 thanks. I'm looking into setting up RAID1 as an automatic back up system. I wanted to be sure that if one drive dies, the system would be on running. It's for my own PC, I'm the "admin" you could said. What form of notification do you get when one of the two drives goes bad (or is removed) ?
Say I already setup the raid 1 like you showed in the video, if I put map network drive on drive a, will it also mirrored to drive b?
so what do you use as a backup then?
this does not work on HDDs more than 4 tb
thanks 🕺🏽
Hello Frazer, thnx for this nice video. I have 2 questions: 1-) Can we do this RAID 1 mirroring with 2 external hard drives? 2-) How do we know if one of these mirrored drives fails (breaks down)? Thank you...
@@FrazerForbes1 Thank you very much for the detailed information. You explained it all quite clearly. Wish you the best...
Why quick format over regular?
Should be because there's nothing on the drive to begin with since they are brand new. If used, then full format would be better to erase everything.
Thank you. Makes sense... Appreciate that
usb = 3gb/s sata = 6gb/s
will this work with 2 ssd's?
if you want something to be really safe I'm pretty sure HDDs are the way to go bc if a SSD kicks out you can't recover the files, plus if it is a fail safe you won't need the extra speed of an SSD anyway.
@@j.hateshisjob5137 ok, thanks very much
Why wouldn’t you use Raid 1 for backup? I would think this is the perfect solution for backing up your files so that even though it’s mirrored, you should always have at least one drive with your files just in case the other fails.
Because if one drive writes down corrupted data, this will be mirrored over to the second drive rendering both useless. For backup I would suggest RAID 5.
This is not raid this is mirroring
RAID 1 is "mirroring".
So Usefull! Thanks bro
Thanks for sharing.
