Lets talk "redundant"

post #1 of 13
Thread Starter 
I see this thrown out many times on here. BUT i havent seen a thread that explains good procedures to address when setting up a valuable network with crucial data. SO.... what are some good, basic practices, hardware, etc. etc. (such as a router) that offer redundancy for small business owners. I would like to able to feel safe with my data onsite. Needless to say i have no clue how to do this other than plug some computers together with a switch/router and enable RAID in the BIOS.

Redundent simply means you have more than one location for data or that you have more than one way to store it.

A simply way to do this is to set up a RAID5 then network that computer to the rest of the house. This setup offers you 1 drive failure and when it does die can put in a new one and it will rebuild itself automatically.

Another way is to setup a NAS box.

Depends on your budget and goals.
You can scale from one server with a 2 disk RAID 1 array up to multiple WAN links with multiple failover firewalls/routers, multiple servers in a SAN environment,etc etc etc

In either situation it's a good idea to have some type of off site backup as well.

So... you're actually talking about "data protection" and not just "redundant" .

In such a scenario, RAID only provides redundancy in the event of hardware failure. You still need regular backups to provide against data corruption (AND hardware failure). After that, you can then look into High-Availability to provide maximum uptime for your users (as well as redundancy). Finally, after that, you can address Disaster Recovery.

There was a study done a couple of years ago that said that only 20% of all SMB had a Disaster Recovery plan... and a DR-situation tends to wipe out any small business that doesn't have such a plan. Such scenarios include flooding, electrical issues, gas explosions, tornadoes, etc. Or maybe even a complete failure of the entire system your data is running on.

Anyways, there's a ton of information out there. If you're looking to learn, Google is your best friend. If this is for a practical, production environment, it's time to shop around for a company that can implement these solutions for you...

If file security is what you're after, get multiple box's with RAID'd HD's in, position them all in different ends / locations in the building. Make the drives mirror each other, and have atleast 1 drive hot-swappable per box so if you need to leave fast, you can take all your data with you. Also, have a box that you back up to monthly, so if you need data from a while back, you can get it from that one. (should wipe out the issue of data thats corrupted, but you only find that out a week or 2 later). Use atleast 2x gigabit connections to these boxes and have a 'private' network link between these storage boxes.

A NAS with raid 1 im assume ya after?

I've seen NAS's with fireproof/heatproof cases, that could be a consideration, along with them being locked, and deadbolted to the floor

The biggest idea though, would be the use of tapes to backup each day/week/month.

Here's a example

Four Drives in RAID 10 or 0+1
Best for: When performance and data protection are both crucial.
RAID 0+1 or 10 basically is a combination of RAID 0 and 1.
Using four hard drives, you get:
- The capacity of two drives.
- Redundancy, so if a drive in any cluster, or two drives (one from each cluster) fails, you do not lose data, you are still able to use the PC but just like RAID 1, you will need to replace the drive and rebuild the RAID array before regaining redundancy and data loss protection.

If the data on your pc is crucial and/or needs to be shared on a network with other computers, a NAS (Network Attached Storage) is an investment to look into.
