Lets discuss backup - Page 8

post #71 of 76
I was looking for a fault tolerant solution for my home media last year, that would also not break the bank. After all the research, I decided against RAID 5 due to a dual drive failure will lose all your data. There has been research done, and the more data you have the higher percentage you will have a dual drive failure in a RAID 5 setup. This also includes a failure of a second drive during a rebuild.

If you are looking at a NAS solution, I would look at unRAID. It has several benefits over raid five. The author of the software is also looking into P+Q in a future release so you could recover for a two drive failure.

You can use the base license for free if you want to test it.

Thus why RAID 6 was created, though there is such a small chance of a drive dying, and even less so of two dying during a rebuild period that it isn't too big a deal.

plus i already looked at lime wires servers but didnt think they would be viable with what im doing.

I realize that is why RAID 6 was created, but he also has the following drives: "4 2TB drives and 10 1TB drives" which to my knowledge they all could not be used in any RAID array due to the different size requirements. However they could all be used in unRAID. unRAID would also fit his financial limitation, along with allowing him to expand the server whenever he needed to. You don't have to break any arrays to add space to this device.

I don't understand why it wouldn't. You actually posted a link to a NAS device, and have been asking about them. unRAID is just a NAS using a Reiser file system. The Pro license will also allow you to use Active Directory permissions.

Just my 2 cents to offer you another solution...

i was looking at unRAID's server as an alternative to a NAS here

Just keep in mind, you can build one yourself out of spare parts you already have. The main thing is to verify there are no issues with the NIC you use.
The "Basic" OS is free for testing.

http://lime-technology.com/products/registration-keys

Feature Basic Plus Pro
Maximum Array Width 3 6 21
Cache Drive supported No Yes Yes
User Level Security (see note) No Yes Yes
Active Directory No No Yes

If you get the PRO license you will have 19 usable disks for data. One will be a parity, and one for cache. 19 x 3 TB = "a bunch of space".
You could actually make two small ones, and have them replicate the data from one to the other if you wanted.

They have also go Crashplan working on it too. I have personally not used it though.

If you wanted a rack mount solution, you could use the Norco case.
