Symlink it back so the app would be able to use it.Move everything from ~/Library/Application Support/Bitcoin/ to the image. ![]() Save it somewhere you won't lose it (like your Wuala, Dropbox, Strongspace or whatever).Click New Image and choose a big enough size, 128-bit or 256-bit (faster or more secure) encryption and single partition.Consider the risk due to theft, fire, or natural disaster in proportion to the value of bitcoins stored in the wallet.įollow these instructions to backup all the bitcoin data (wallet and block chains) to an encrypted disk image. Once a copy has been made, encrypt it, and put it in two or more safe locations. The other way is to use the backupwallet JSON-RPC command to back up without shutting down Bitcoin. To make a copy of the wallet.dat file, ensure that Bitcoin is closed and copy this file somewhere else. The only file you need to back up is "wallet.dat" which can be done one of two ways. Make sure to pick a password that is memorable but secure. Whether you use Dropbox as your backup or not, it is advised to use what Steve Gibson calls "pre-Internet encryption" which means to use some form of encryption on your files before you back them up, in case an attacker gains access to that backup. Wuala's servers do not store your encryption key and the program authenticates with the password each time it is started. After it authenticates once, the server assigns it a token which it uses to show that, at one time, its user knew the password rather than sending the actual password (meaning that if you ever use the Dropbox client on another PC, that PC's users can access your Dropbox - even if you change your password - and can steal your bitcoins or get a virus that will steal your bitcoins).įor these reasons, an alternative that always uses password authentication such as Wuala should be used. the Dropbox client only needs a password for the first login.Dropbox stores your encryption key (meaning that a disgruntled Dropbox employee or an attacker who gained access to the system could decrypt your Dropbox data and steal your bitcoins).Note: Using Dropbox to back up your Bitcoin data is not recommended as doing so introduces the following security concerns: If you have trouble browsing to these folders, note that "AppData" and "Application data" are hidden by default. ![]() For most users, this is one of the following locations:Ĭ:\Documents and Settings\YourUserName\Application data\Bitcoin (Windows XP)Ĭ:\Users\YourUserName\Appdata\Roaming\Bitcoin (Windows Vista and 7) Go to Start -> Run (or press WinKey R) and run this:īitcoin's data folder will open. To change the directory Bitcoin stores its data in: If that's not it, you can do a search like this:įind / -name wallet.dat -print 2>/dev/null ![]() You need to do a "ls -a" to see directories that start with a dot. The data directory is the location where Bitcoin's data files are stored, including the wallet data file.īy default Bitcoin will put its data here: 2.4 Automated backups using Cron, Bash and GNU/Linux.2.3 Email-based Archival and Remote Backup.“ voilà”, in Trésor de la langue française informatisé, 2012.In face-to-face conversations where both participants can see the subject of the conversation, voilà often supersedes voici (thus its additional definition: Here is).It is mainly used to introduce a slightly distant person or object, in contrast to voici which is used to designate a person or object near the speaker.Its only conjugation is in the present indicative tense, even though it can appear in phrases that imply another tense. ![]() Voilà ce que je lui ai demandé, et voici sa réponse : « . » That's what I asked her and this is her answer: "."
