Just to add to Tesserax.. when you wipe and reload the OS on a computer you have created a new computer.. Your Mac no longer has ownership of the previous backup.
Migration Assistant then allows you to move your files and settings and apps to the "new" computer.
Hmmm.. when you say you recreated the account.. that may not be the best way to do things.
Migration of user files and settings will recreate the user on the computer.. if you have already created a user of the same name, then migration assistant will need to change the name..
I have not done a migration for a while.. especially using the more recent OS.. so read carefully the info Tesserax has given references to.
Also although old this info is still useful.
