Re: [Duplicity-talk] Re: How to run duplicity with a Cron Job

[Mathias de Riese]

Hi *,

I did some modifications to allow encryption with a public-only key and 
signing with a separate private key
which is then of course less secure. I thought i sent the mods to the 
developer, but i might have postponed that
and then forgot. I use the following script started daily from cron for 
quite some time now:

<snip>
export PASSPHRASE=""

duplicity -v 4 --archive-dir /root/duplicity/ --encrypt-key XXXXXXXX 
--sign-key YYYYYYYY \
              --include /home --exclude '**' / 
scp://address@hidden/home/bckusr/hostname
<snap>

The trick is  that the information to do the incremental stuff is also 
stored locally and unencrypted in
/root/duplicity/ and the private key of the encryption key is therefore 
not needed. When i downloaded
duplicity this didnt work, because duplicity would use the --archive-dir 
to store that info, but would
not use it in the next run -- at least not completely. I fixed that in 
the code and therefore it
works with me.

If it is not in the public code, let me know and i will send you my 
mods. (Need some time for that, cause
i completely forgot what i did over my thesis work...)

Cheers,
Mathias
