I doubt glitch would make you lose data on both drive since the software supposed to perform read-only operation on 1st device, unless the software is badly written.

I meant "glitches" including anything from malware to accidentally deleting data by yourself. That's why I prefer multiple backups that aren't connected at the same time.

Usually the latter is more likely to happen especially if you are using dd command and you fudge the output block device name.

okay so I have 1 node/wallet done using bitcore 25.

lets go the route that I only want a cold wallet.

I don't want a seed style for back up.

have just 1 copy of core and wallet dat on 1 pc turned off is not acceptable.

So Joyce how would you back up this core offline wallet.

3 clones of the ssd would seem to be good to me.

Or am I missing something.

Lets say
new core
new wallet
new address
pass word to open it.

clone 3 copies.

I know I could just copy wallet.dat

but I rather have 3 copies of the working drive.

or am I over thinking how to safe guard the wallet.

I do not want a hardware wallet.

I guess electrum could be an option

An Electrum personal server such as EPS and Electrs can be hosted on the PC running Bitcoin Core, and then from another PC that is airgapped from the internet but on the same LAN as the other PC (required so that you can send transactions), you can run electrum and use the IP address of the Bitcoin Core PC as your electrum server.

But if you don't want to dink around with electrum there is a way to run Bitcoin Core offline, see this wiki for details: https://en.bitcoin.it/wiki/How_to_set_up_a_secure_offline_savings_wallet#Setting_up_an_offline_wallet_from_scratch
