I have the original backed up on a different computer, will this suffice or do I have to back it up on the device I am currently syncing on? Also, I watched a couple tutorials on how to back it up and I am seeing people using "back up" from Bitcoin Core to achieve this. Is there another method to back it up?
Cheers!
First, copy the wallet.dat file to another location to attempt to open that (you don't want to destroy the only file copy you have).
Now you can download "pywallet" from Github and use that to print the private keys inside the wallet file. This only works if the wallet is not encrypted, or it's encrypted and you have the password.
