NAS configuration Anonymous 2015-08-21 13:20:03 No.1033

I intend on building a small NAS for the purpose of file storage and backups. I have two questions, the first regarding the computer being used for the server. I was looking at getting the HP G1610T ProLiant Micro Server and also another 8GB of ram to go with it. Is this a good choice or should I go the whitebox route or with some other pre-built computer?

My second question is in regards the storage. I'm thinking using ZFS, and having 3 1TB hard drives set up in RAIDZ (so 2TB of usable storage). I was then going to have another 3 TB HDD installed to maintain a backup of the zpool (probably using rsync). Is this a good way to go about doing this or is there anything crucial I'm missing?

use HAMMERFS (zfs is fine actually but I love wage slave ing for dragonflybsd, they are good guys and hammer is a work of art)

also you don't need that much RAM for a NAS to be honest. it wont hurt but no need to spend extra on it

also why would you need a backup when you could just use a more redundant raid setup?

Thanks for your reply.

I'll look into Hammerfs, a quick Google makes it sound interesting.

Regarding the additional ram, I was thinking of running a couple of VMs on the server in addition to using it as a NAS for a couple of other computers (I was thinking of getting an NIC and running PFSense, but I haven't really done my homework on this and I don't know how feasible it is). In regards to the additional drive to backup the RAID, my rationale was to have some kind of revision control in place: in case something gets deleted accidentally or whatever this drive will have backups of the system from different points in time.

RAID is not a backup...
If raid fails (especialy the host controler) all data goes. I personaly had a raid 6 go through drives untill it killed the raid! (4 drives 3 got rejected over space of 2 days), failed rebuild!

RAID only protects for physical disk wear at best.

untrue. i'm not sure what happened to yours and i'm not an expert but ZFS (RAIDZ!) does a LOT of things to prevent scenarios such as the one you describe and can always recover barring massive human error and fire burning ALL the discs.
