Hi,

So my truenas was running fine till yesterday. I am running it via sd card on an old Acer Aspire One 725 netbook that I had spare.
It ran absolutely fine for over a month.
Today Its giving me this error, although I shut the system down for a few hours then started it and it worked fine. I copied a few files they copied fine.
Then I logged into truenas to see if I could get a backup, I logged in fine but then couldnt access any settings.
When I went to check it was giving me the same error.
What could be the issue?
If i'm supposed to reinstall truenas, how can I restore the backup I made earlier?
(the backup was made about half a month back, I haven't made any configuration changes since it was made. Only files have been copied to the nas drive)
Thanks for any help :)

via sd card

Not a great option

on an old Acer Aspire One 725 netbook

Also a terrible option

What could be the issue?

Your boot media has died. You'll need to look at a new one (ideally reconsider your whole setup if you want reliability, but at least switch to a small SSD via USB for boot)

If i'm supposed to reinstall truenas, how can I restore the backup I made earlier?

Yes, that will work.
