Absolutely, I will store the file encrypted in different places this time. I think I will stick with the wallet.dat backup option + strong passphrase.
Remember to write down your strong passphrase. You will lose your coin if you lost your strong passphrase and won't be able to get access to your private key in that encrypted wallet.dat file.
I made that mistake because I thought I can remember the passphrase. After I did not open the wallet each week, a few months later, I forgot the passphrase and lost my coin. It's bad memory and terrible lesson.
