Hi xeldal, Thank you for your comments. I might not be right but I somehow remember... when I created BitShares wallet very first time (more than a year ago), I had a message on a page to create/save a backup file. So, in my mind, I'll be better to create and have a backup file (my account and balance information) and save it safe.

But if we use Cloud Wallet, we just need to keep our user name and password. We do not need to worry about creating a backup file. Put your trust and keep your account name and strong password safe (and remember). If you still feel worry, then, you can create a backup.
Maybe think like that?
