This is another way to make an online backup of your wallet.dat.
These are the Windows instructions, but they can be done also on others ( linux/osx )
English isn't my mother language, but I hope you will understand it Smiley

Requirement:
- Java

1 ) Go to Wuala and click the "Download" button and install Wuala

2 ) Register a free account, you will get 1 GB
Optional:
Go here and do the same: C57JF5BJJ5MP7CPP4AFF
You will use my ref and you will get 2 GB instead of 1. ( I'll get 512 MB )
You have to use this ref before all other promo codes.

3 ) Go here and use all valid promo codes: http://www.retailmenot.com/view/wuala.com
You will get many more free GB Wink
Use them here: Tools->Options->Buy storage->Promocode:

4 ) Go here Tools->Options->Trade storage and enable it ( set it as you like, 1 GB is enaugh )
You will get Pro features Backup and Sync free!

Option 1
( another data folder )

5 ) Create a new folder on your Bitcoin folder, example:
C:\Program Files (x86)\Bitcoin\Data

6 ) Add it to a new backup folder in Wuala. ( NOT a Sync folder )

7 ) Now open settings of it, Show settings

8 ) Change Interval to Continuos and Filter to:
blk*.dat,.lock,*.log,database,*.0**
( you will only backup wallet.dat and addr.dat )

9 ) Close Bitcoin if it is open.
Copy all files from %appdata%\Bitcoin to C:\Program Files (x86)\Bitcoin\Data

10 ) Run Bitcoin with this command line:
bitcoin.exe -datadir=./data

Option 2
( Default Bitcoin data folder )

5 ) Close Bitcoin if it is open.

6 ) Add the default Bitcoin data folder to a new backup folder in Wuala. ( NOT a Sync folder )
Example: C:\Users\[your_user_name]\AppData\Roaming\Bitcoin

7 ) Now open settings of it, Show settings

8 ) Change Interval to Continuos and Filter to:
blk*.dat,.lock,*.log,database,*.0**
( you will only backup wallet.dat and addr.dat )

9 ) Run Bitcoin

You can find some other ways to do it, just try Wink

Wuala accepts Bitcoin and I think it’s actually cheaper than with USD, by the way.

Wow, I was not aware of that! This is cool, I find wuala better than dropbox. Actually, it's the best remote backup provider I'm aware of. (if anyone has better suggestions, I'm accepting them Smiley)

It's a quite cool way to share files with other people too.

Wuala crypt files locally and then upload them to their server.

If you lose your password, you will lose everything. ( on Wuala, of course Wink )

Since everything is encrypted before being sent to Wuala, is there a problem in just making my wallet.dat a soft link to a file inside the directory structure Wuala automatically created on my home dir?

I've tested and it seems to work. It seems easier than making all these filters and everything.

Wait!
I don't understand, but it seems that you have found a better solution! Cheesy
Can you explain it again with other words?

Where did you put this "soft link" ?

example:
1) put the wallet.dat on a Wuala folder ( ex: W:\myfiles\folder2\ )
2) go in bitcoin data folder ( ex: C:\Users\[user_name]\AppData\Roaming\Bitcoin ) and delete/rename/remove walled.dat
3) open CMD and go to the Bitcoin data folder
4) write this:
mklink wallet.dat W:\myfiles\folder2\wallet.dat

Is it something like this? Smileyù
Does it work?

Yes. Well, I haven't tested the wallet yet, but I tested with some text files, and when I changed them using the soft link, the Wuala software would show me the changes. I logged to my Wuala account from another computer and I could also see the modified file there.

One thing I haven't managed to figure out about Wuala so far is if the files they store on my computer are already encrypted, or if they are only encrypted before sending to the network, but on my disk they are unencrypted. If it's the latter, I'd have to use a second layer of encryption (Wuala+Truecrypt maybe?) if I don't want my wallet file to be store unencrypted anywhere.

I think that with your solution ( a very good solution! Grin ) the walled is only encrypted on Wuala servers.
It will reaming unencrypted on your local harddisk.
Anyway, devs are adding a new encryption feature on the official client Wink
