Re: [rdiff-backup-users] backing up a Bitcoin wallet (private key)

[Gavin]

I  rdiff backup everything onto a LUKS encrypted file system.
Because the same problem applies to ssh keys, leave them lying around on a portable drive...?

The LUKS file system needs a very long password to mount (which can be changed at any time).
Normally the drive is umounted and a script is run to mount only for duration of backup.
See cryptsetup.

Rdiff-backup is a program not a backup system, something like backupninja can be placed in front of it to run scripts, scheduling etc.

password, the rdiff-backup repository will still contain the private
key encrypted with the non-secure password.

Yes, backing up sensitive data is hard =)

Just a few thoughts:

 - The bitcoin wallet doesn't change, so there's no need to back it up
   every day. The easiest is probably to exclude it from your normal
   backup, as Dominic suggested, and just copy it separately.

 - If you think your wallet might be compromised in any way, it's
   probably best to make a new wallet and transfer all your bitcoins.

   key as well?)
