It pays to also have a copy of the private keys of w/e addresses you want to keep in case funny business happens.. this way you can avoid messing about with corrupted wallets or even accidentally backing up a corrupted wallet and just drop the private key in and watch it resync as per normal.
I agree with you Joori.
just for anyone curious on how to get private key of your addresss:
you can use the console command
dumpprivkey
you can import to another wallet with
importprivkey
remember your private key is essentially your naked address, anyone who holds your private key can do ANYTHING to the funds inside your address
