It does, actually, and I had it on, which is why I'm perplexed about the fact that my last backup in my email account is too old. I was so sure it would send the backup automatically, that I didn't bother to check I actually got it 

I consider myself very well versed in all things Bitcoin. I posted about my hopes to restore my private keys for my blockchain.info wallet, after witnessing the very long downtime following today's DDoS attack, and realising that my latest backup is a little old and doesn't include a new address I generated with a few coins in it.

Here's that post: https://bitcointalk.org/index.php?topic=179825.0

I think it shows I know what I'm talking about, and I would really like to post it on another board here so I can hopefully get some ideas from the community.

I've been lurking here for some months and just didn't know there's a cooldown period, I would have registered a very long time ago had I understood that..

So, I've spent a lot of time researching various methods when first getting into bitcoin some while ago. I eventually went for blockchain.info, and implemented some strict security restrictions.
I also made sure I have backups in various places, so that I can use a local client if something happens to blockchain.info.

So, now blockchain.info is down for many hours, and I reached out for my latest backup. To my disgust, I realized I wasn't rigorous enough, and created a new address a few days ago with ~5 BTC, and didn't have the wallet backed up since then, so I don't have the keys for it in my latest wallet.dat backup.

I do have the keys for another address where most of my coins are, but still, this new address with 5 BTC is out of reach for me right now.

Let's assume blockchain.info never comes back again (unlikely, I know). Is there any hope to restore this address? I have the blockchain.info app on my iphone, logged into my wallet and I can see its details, with the new address, there. Of course I can't transfer any money because the blockchain.info server is down. I'm pretty sure the actual wallet.dat is stored there - but how can I access it? Anyone knows?

Maybe I have a copy of it in my browser's local storage?

Any ideas? Of course best thing to do from now on is to be on top of my regular backups...
