You might be utilizing bitcoin CORE with the default folder in appdata?
so the situation of the complete information folder (together with the whole blockchain, and pockets.dat (the place your non-public keys are) is in:
%userprofilepercentAppDataRoamingBitcoin
copy and paste all that in a folder contained in the USB drive.
specifically care with pockets.dat, reserve it into TWO completely different drives, not one!, by no means do CUT and paste, do at all times copy and paste, and do not drag n drop both it is harmful specifically with touchpads hehe, if you do not have two usb exhausting drives for the complete blockchain, do a full backup in your USB drive, after which save in a flash drive solely the pockets.dat.
it’s one factor to should obtain the complete blockchain as a result of your USB exhausting drive died, and one other is loosing all of your bitcoins so, pockets.dat , TWO copies (keep in mind, copies implies that the file is in your pc AND on the units) the extra the higher.
RESTORE: (my approach, possibly there are different choices, that is how i did it, a number of instances! when defender screwed my blockchain information folder)
set up bitcoin core (ideally the identical model!, but it surely might be older, it really works)
RUN IT
as soon as it says sincronizing, shut it.
(that is so the pockets will create the info folders)
now go to:
%userprofilepercentAppDataRoamingBitcoin
and delete the whole lot inside, and exchange it along with your copy out of your USB drive backup
