To clarify, RAID is *not* a backup at all. Backups are independent copies of data from a single point in time, stored on a separate storage device. This means that you can restore from backup when someone deletes a file or downloads malware, or if the entire building burns down (assuming you're using 321). Most RAID configurations are redundancy solutions, and the rest are just a way to speed up reading and writing to the drives. If you're using a redundant array and one drive fails, that failed drive can be replaced and the data can be recovered, but that won't protect you from the other mishaps that backups protect you from.
To clarify a briefly, RAID is a storage architecture that (for RAID1+) leverages redundancy for partial-loss recovery. This means conflating RAID with a backup is meaningless without further context - RAID answers the “how” question, while “backup” answers the “what” question.
He didn't say RAID is a backup solution , he said he bought a NAS to store backups on and that he configured said NAS with RAID to prevent the loss of data that happens when a disk fails. However , since i think you know too , sometimes all disks go at the same time , or sometimes just too many disks go at the same time or or or....so that's why 3 2 1 strategy exists.
RAID stands for Redundant Array of Independent Disks (or Redundant Array of Inexpensive Disks). It's a data storage virtualization technology that combines multiple physical data storage components into one or more logical units for the purposes of data redundancy, performance improvement, or both. Key Points: * Data Redundancy: RAID levels like RAID 1 and RAID 5 use techniques like mirroring and parity to protect data against drive failures. * Performance Improvement: RAID levels like RAID 0 use striping to distribute data across multiple drives, improving read and write speeds. * RAID Levels: There are various RAID levels, each offering different trade-offs between redundancy, performance, and capacity. Common RAID levels include: * RAID 0: Striping for performance * RAID 1: Mirroring for redundancy * RAID 5: Striping with parity for both performance and redundancy * RAID 6: Striping with dual parity for higher redundancy Benefits of RAID: * Improved Reliability: Protects against data loss due to drive failures. * Enhanced Performance: Can significantly boost read and write speeds. * Increased Storage Capacity: Allows for larger storage pools by combining multiple drives. Considerations: * Complexity: RAID setups can be complex to configure and manage. * Cost: Requires multiple drives, which can increase the initial cost. * Data Recovery: While RAID protects against drive failures, data recovery from a failed RAID array can be challenging and may require specialized tools and expertise

fully agree with the 321 approach. I had a nas drive several years ago and I thought i was good to go.. little did i know the motherboard of the nas drive failed and screwed me up. I was too young back then. But ye, now I got different types of nas drives and a cloud storage with snapshots.
Or you could have built your own, rolled True-Nas or something similar and don't it for about half the price and with much greater customisation options.
While services like unraid and trunas might be great, some people don't want to necessarily troubleshoot. Some are fine paying the premium to not set up their own nas from the ground up. I prefer DIY but some just want the work done for them
@fueluz48 completely agree. But this is a tech channel... Don't tout the "cost saving" benefits of a premade NAS when someone like this should have the ability to easily DIY it
@@captainwasabi This is the damn truth. I'm a programmer and I know my way around basic IT, but don't give me tasks like these. I will totally fuck it up. I can build a PC and do some basic troubleshooting for hardware. That's about it.
Another thing to consider is that if there are errors on a software, then they are correlated! I.e. consider running diff types of redundancy software on the drives
Welcome to homelabing!! Good intro to self hosting git , vscode server, infra as code. Next step, buy 3 cheap nucs/mini pcs and make a proxmox cluster with ceph and put what you want on top.
Please don't mislead people. A 4 bay NAS running raid 6 Can survive two failed drives. Please read up on raid 6. Also it's Network Attached Storage (NAS) Not Network Attached backup. Storage is the key word here.
I have a server rented in the cloud that i have all my data on. It has only two drives. Since there is neither redundency or a backup i am planning on a restic backup to a local server that runs raid 5 with a hotspare.
Use a DDNS, you can get a subdomain name for free, and with some work on your router, it will always point to your dynamic ip, + port forwarding should be free no ?
Wait... With most cloud storage you get disaster recovery (aka 3 copies in different data centers), maintenance and electricity fee for free. Also you don't need to spend money and time in network security... are you sure you saved for storage? Have you put the price of the hardware NAS, the harddrive, the electricity, the ups, the spare harddrive you need to have and substitute, harddrive maintenance (generally replace hard drives every 5-6y), Nas maintenance(if it breaks), ups battery swap every 3-4 years, plus the off-site backups?
@piotrjankowski5850 yes, tho you might not have to spend money for network monitoring, not really mandatory... However for HA you need 3 copies: so 3 NAS, in 3 different locations at least 300km apart (~200miles). That's what I meant as a "datacenter"...
@@alessiozamboni4694 I know 🙂 I agree with you, there is a trend for home NAS while cloud storage may be cheaper in some scenarios. As for privacy this is not an issue with end to end encryption.
6TB of Apple storage is $33/mo, then music streaming would be $12/mo, then I need to pay for streaming services ($20/mo lets say), backups $9/mo. $75/mo not including other projects. $900/year, it could take 2 years to pay that off in hardware. Self hosters often host family too, so there’s hundreds each year family gets saved. Not to mention, it’s a hobby and a great tool to learn. I’ve spent $300 in the last 5 years for hard drives on my $250 server. I have about 15 active VMs (that’s about $150/mo right there). It can be easy to save money, just depends. My electricity bill is low, maintenance is my hobby. Why would I budget for hired labor when it’s my hobby?
Synology is such a rip-off. Their drives are twice as expensive with high error rates. I have 2 DIY NAS’ with 19 drives each and I’ve only ever had a single drive failure. With the Synology, the cache drives failed,the chassis had to be returned 3 times due to failures, and 1 of the 4 drives failed. You can build a much better NAS with equivalent storage for less.
Don’t do BTRFS RAID56 either. If he’s doing 3 disk raid, he’s better off doing literally anything else. But it looks like synology and I recall they do single disk btrfs volumes and LVM or mdraid to do the disk management
There’s a risk to anything on the internet, period. If you aren’t skilled in locking down your server, don’t self host something you expose to the internet. I’ve self hosted 10 years myself. No incidents
Yeah it’s about $50/TB/year with S3 if you aren’t planning on regularly accessing it. Not too bad unless you have multiple terabytes. Best kept for business only though, use something like backblaze or any other cloud provider for personal storage backup

Thanks to Tux for coming and chilling
Hi sir,
How would running docker on privately saves subscriptions?
Please explain if anyone knows
That NAS costs more than me and homies included!
You should make a detailed setup video
I was expecting him to promote his own service at the end lmao
Chapeau

and you dont pay for google drive, netflix, hulu, disney, cable tv, onedrive, email, game servers, or hell even premium services on a router@_hepl

Please read up on raid 6.
Also it's Network Attached Storage (NAS)
Not Network Attached backup.

Didn't he say "Network Attached Storage server" instead of "Network Attached Backup server"?
Many of us are still waiting for any signs from Synology. I wonder if they are dropping the prosumer market with their lack of refreshed hardware.
Perfect playing environment
Wish my NAS looked so cool, just don’t wanna buy one. I’m using a giant old school full tower with a 3rd gen core i5 and tons of HDDs
I also have one of these except it's just an old PC with a bunch of sata drives
Thanks for such a valuable information.
You're a real tech channel
I have a server rented in the cloud that i have all my data on. It has only two drives. Since there is neither redundency or a backup i am planning on a restic backup to a local server that runs raid 5 with a hotspare.
What provider is it on?
Every update they remove features rather than adding features..
Great. Now I need to pay my internet service provider for static IP and port forwarding.
Use a DDNS, you can get a subdomain name for free, and with some work on your router, it will always point to your dynamic ip, + port forwarding should be free no ?
Not with a Synology NAS.

Ever heard of Github as a programmer?
What about those punctured disk restorations. Oof
That nas server probably costs more than a mid level gaming PC, what subscriptions do you have to save that much

probably more than my paycheck 😔 (00,000€)
Please tell me you didn’t use raid and actually used BTRFS…

You can deploy your web app with it ?
yes
why even advertize it if your NOT EVEN
saying the name
How do you know if you or when you need this
If USB sticks aren't enough. I read those should only last 2 years between reads, but Oracle recommends reading all data once a month.
@ thank you
Why not aws s3?
Do you want him to go bankrupt? xD
Yeah it’s about $50/TB/year with S3 if you aren’t planning on regularly accessing it. Not too bad unless you have multiple terabytes. Best kept for business only though, use something like backblaze or any other cloud provider for personal storage backup
Waste of money, build your own
Thats not what NAS means lol
raids is horrible lmfao
Never buy Synology
Why?
