I am a novice with RAID and could use some advice on how to make my data more secure and still maintain access.
I want to store about 2 TB of data (family pictures, projects, etc). Currently I use 6 500 GB Maxtor external drives and a couple of 300 GBs. These mirror they data and can be kept disconnected from the network. I am running XP.
But I find that the drives fail frequently, that the mirroring is asymmetric (and data difficult to find / access). I am looking to spend ~ $2000 and have been considering RAID 5 or maybe RAID 6 solutions. This would be my only database when done. Can anyone suggest a stand alone plug in box (? Terasyn) that would fit the bill. Would an Apple setup be better to ward off viruses.
The only real security is redundancy. Even companies that use a RAID array for their databases backup the data to an external source for long term storage. The purpose of RAID is to protect against a hard drive failure, not long term protection. Backing up the data to DVDs and/or using online backup services would offer the best protection for your data.
There are many many way to do this. First make sure you understand that redundancy and backup are 2 different things. Redundancy will keep you alive with a mechanical drive failure. Backup will keep you alive when something corrupts your data and you need to restore it. Its a good idea to have both when possible. I have a RAID array in my main machine and a dedicated home server. I also have REALLY important stuff burned to DVD.
Like I said there are a ton of options to choose from to keep your data safe. I would first have a RAID array in my machine. You could even take 2 of the drives you have and RAID them inside your machine you have. For backup I will give you a low end example. Get an older machine and install the rest of your drives in it. Load an OS on 1 drive and create another RAID array on more drives. For a file server it is not necessary to have a super powerful machine. If you like this example I can give you more details if you need them.
Another option would be to use a NAS option. You can use a platform called freenas http://www.freenas.org/ . It would use the same low end computer and make a NAS out of it.
This is just 2 options and you can get much more expensive with this concept.
