Re: [PLUG] Is it possible to move data from a SAS drive to the newly installed SSD?

[H Mottaleb via plug <plug@lists.phillylinux.org>]

So, i don’t have to have the raid setup if I continuously back it up? How about moving the data to another system with a ssd?

I hadn't even thought of that, but, yeah, that is probably a thing.

That said, you might get better results with one cheap $50 SSD and
backing it up than with playing around with a bunch of expensive
enterprise drives, especially if they're spinning.  Assuming you can
just plug a SAS cable into your existing HBA you can just get one of
those SAS-SATA breakouts.

Or if you have a free PCIe slot (or especially M.2) then get an NVMe
card.  Not sure if you can get those in PCIe slot format cheap these
days.  You probably also could get an M.2->PCIe adapter.

You could just go with RAID1 on that if you want, or just back it up
regularly.  Really the only thing on an ETH server that is critical is
the wallet file which doesn't actually change unless you generate a
new account, so you can just back it up safely after generating an
account and before putting any ETH into it.  If you're putting
substantial amounts of money into your own wallet I would highly
recommend having a bunch of safe backups of the wallet keys
regardless.  If you lose those files, there is no way whatsoever to
get your money back.  On the flip side if somebody else gets a copy of
the keys in those files, they can take your money and there is no way
to recover it after the fact.
