Hello all,

I just bought an external hard drive and set it up as encrypted using the
2 links below.

When I am on the road I would like to be able to back up the changes on my
drive to a machine at home.

I don't want to send the files over the net unencrypted. I have encrypted
the entire drive not the individual files. The drive is 500GB so I can't
just back it all over the net.

Is there a way to use something like rsync to just back up the changed
parts of the drive or??

Here are the links I used to encrypt. It was very easy to do.

Any suggestions would be very much appreciated.

Thanks in advance,
Steve

scp/sftp

rsync works fine here too, just tunnel it via ssh

Thanks for the help.

When I back up the drive do I just mount it without using the command
cryptsetup luksOpen /dev/sdb1 encrypted_drive?

If I issue that command it will un-encrypt the drive.

Just mount /dev/sdb1/ then use rsync on the entire drive?

rsync is file based. It synchronises directories and their contents.

I don't know anything about cryptsetup. But obviously rsync has to be able
to read the dirs and files on it, just like any other program.
