[Duplicity-talk] trying to convert my backup script

[turgut kalfaoğlu]

I am trying to convert my backup script that copies files to my external 
drive to use duplicity, so I can benefit from its encryption features, 
but I'm having no luck.

My script uses rsync to backup a variety of directories, such as 
/var/www /home/turgut, /etc to the external USB drive.

I am unable to specify more than once source in the duplicity command 
line..  I tried specifying them all, duplicity said "too many parameters."
I then tried the --include option, then it complains of not enough 
parameters.
Then I used  duplicity / --include /var/www --include /home/turgut 
--include etc /run/media/turgut/usbdisk
but it complained that  /  the source already includes my specified 
directories!

If I divide this work into many different calls of duplicity, one for 
each directory, then the script stops and asks me for my gnupg 
passphrase every time, so that's ugly too.

Help!
Thanks, -turgut
