Trying to create a "live" backup

[Nunspa]

Greetings

I just built my first NAS server for my office, I had a smaller pre-build one which no longer fulfilled so needs so I built a system (AMD Phenom(tm) II X4 955 Processor, 16 gigs of ram, 500g SSD for OS, 4 – 4tb western digital HDs)

my office simply uses the system as a shared drive (everyone on windows PCs, mapped network drives) where all my companies projects are stored as well as reports, common shared elements

years ago I had a RAD crap out on us and I ended up losing years of work, we were able to recover a fraction of it so I have become little paranoid. So this is what I want to do but I can’t find a way to pull it off.

I have 2 raids of 2 disks each on in my system, I want one RAD “A” to copy over to the RAD “B” one every day at midnight

before you ask, yes I have snapshots and shadow copies enabled.

when I’m looking for is two things
1) in the case of an emergency I want to be able to just remap everyone to RAD “B” instead of sending everyone home for the day.

2) also allows me to pull file if it was deleted by mistake. Which happens more often then I like.

So I set up a task, Reproduction of A to B it works but when I try to browse it from my PC I get “Windows cannot access <address> check the spelling of the name. Otherwise there might be a problem with your network. Toy try and identify and recover network problems, check diagnose. With an Error Code 0x80070035 the network path was not found.

BUT I was able to browse the drive yesterday (when it was empty) I’m at a total loss.

I’m VERY new to TrueNAS (or any backend like this) so be gentle … lol

in my set up I use to have my old NAS back up to an external hard drive using a program called goodsync on my PC, I know I can just use that on my PC to copy RAD A to RAD B but I rather find a way to automate it within TrueNAS and its more secure that way I would think

anyone?

I question the usefulness of what you're thinking of doing. Your strategy would make sense with separate servers, not with a single machine. The vast majority of problems that would take down one pool would take down two - except for dying disks, which you'd mitigate by throwing all disks into one pool.

So I set up a task, Reproduction of A to B it works but when I try to browse it from my PC I get “Windows cannot access <address> check the spelling of the name. Otherwise there might be a problem with your network. Toy try and identify and recover network problems, check diagnose. With an Error Code 0x80070035 the network path was not found.

BUT I was able to browse the drive yesterday (when it was empty) I’m at a total loss.

You mean you set up a replication task from pool A to pool B? You'll need to provide more details, because your problem statement is a bit too vague, and it's easier for everyone if you post a longer list of steps you took, configuration options you went with, etc.

That said: If I had four disks and one machine, I'd set up a single pool in RAIDZ2. Snapshots then cover your second point:

2) also allows me to pull file if it was deleted by mistake. Which happens more often then I like.

Your other point is not really addressed by this, but that's not much different from the setup you want.

1) in the case of an emergency I want to be able to just remap everyone to RAD “B” instead of sending everyone home for the day.

But really, for anything remotely business critical, setup a backup server.
