Remote Backup

To protect my personal data I have the following requirements:

1) Backup must be remote to cover worst case scenarios (fire, water,
etc)
2) Data access must be secure
3) Data is automatically encrypted before transfer starts.
4) Ideally, certain data can be encrypted and others can be left
unencrypted.
5) Incremental backup must be possible (backup size is huge but
increments are small)

One option is using an online service. I do not feel to comfortable
doing that, though even if the data is encrypted before an upload.

I have family members living on another continent. Both of us need a
backup solution. So my current idea would be using something like a
network attached storage solution. We then would need some software
that can handle all of the above requirements. Note that we do not
have static IP addresses so the software should be able to handle
this. Any input is appreciated.

Thanks

For IP addresses, use some service like dyndns.org.

As for encryption, if you want to only encrypt some things,
best script this yourself with GnuPG for encryption. For
archiver I would recommend plain Gnu tar, which can do
incremental backups. For transfer, a simple passwordless
ssh/scp setup should be fine.

This would require a UNIX or UNIX-like (Linux) server
on the other side. Locally, the same or a DJGPP setup
fro these tools.

I would use rsync over SSH (rsync -e ssh -aP /my/disk
login@host:/my/backup). It's incremental and encrypted on the
wire. The files on the remote are _not_ encrypted, though ; your
relatives will be able to read your files.

There is software to securely backup your data to an untrusted
remote host ; I think it prepares a tarball of the files that
have changed since last time, encrypts it and uploads it to the
remote.
