How easy is it, really, to bruteforce a truecrypt file when the password is 35 characters long? Is bruteforce the only way? It seems like dropbox would be okay if your file is encrypted properly and doesn't stand out. If you name it something random like "charset.dll" or something, who would really spend that much time on it?

Better yet, hide it in a folder with some program that already has a bunch of .dll or .dat files, so it looks like it's just one of the require components Cool

IIRC 8 chars take more than a life-time.

Jack of oh so many trades.

As long as you have encrypted the wallet file using TrueCrypt (strong password + locally stored key file), you should be fine backing it up to the cloud (DropBox, GMail or any similar alternatives).

If anyone manage to get hold of the file (from the cloud), and they are prepared to bruteforce your password, they still need the key file (which is not stored anywhere near the cloud, and only you know its exact location).

You can try with Bitcasa, since the files are encrypted on your PC instead of their servers and then the encrypted data is uploaded to their servers.

I suggest you to keep your encrypted wallet on encrypted USB stick in the safe. It is the most secure way when nobody can get even your encrypted wallet.

I zip mine up and then rename the zip. Most clowns don't know what they are doing when they try to steal. They will do searches only.

Well, there's a wallet just begging to be stolen.

I wouldn't keep it in dropbox, even encrypted.

Stick it on a USB key (encrypted) and keep it in a safety deposit box, or in a relative's safe.

Or for long term storage make a really good brain wallet involving a salt, a complex phrase, and a personal identification number (like drivers license). Salt should be at least 8 characters, dozen preferred.

Stop using branwallets

It's probably fine if you've already encrypted it, but it's better to just print a paper backup in my opinion. Two people can keep a secret if one of them is dead.

As you wrote: Depends how paranoid you are.

Encrypt your wallet and you should be fine

I suggest you put your wallet on a USB as well on your computer. The more backups you have the safer.

Dropbox is safe, if you put a password on the file.

Better put it in a small truecrypt container before uploading.

That's the right way to go about it.
encrypt the wallet.dat - then encrypt the file with 3rd party encryption software and that can go to online storage.

For max. security you could scramble the file before uploading it: http://www.alldataright.com/file-scrambler/screenshots.html

Sinbad Mixer: Mix Your BTC Quickly

In theory, BTSync would probably be a better solution. Less people with access to the files (i.e. decentralized). Same concept as Dropbox, just without the central server, and uses a passkey just to sync (extra layer never hurts). That said, I use both, but I wouldn't put anything sensitive on Dropbox.

I personally wouldn't do it, but if you are uploading an encrypted wallet with not many coins you *should* be fine.
