Is it possible to specify multiple source directories in a
duply configuration file? If not is there any simple workaround?
Make the source your system root
At this article there is a good example of exclude file: http://aguslr.github.com/blog/2012/04/18/backups-with-duply/
Also, you should not backup /dev, /proc and other system folders in a Unix system. Just add them to the exclude file.
If you mean multiple remote directories, you must create a profile for each machine:
actually the above does merely achieve a backup everything while excluding some files/folders. the correct answer would be.
use the highest common root folder that contains all folder you want to back up. using
now modify your
+ /folder1 + /folder2 - **
Note: there is a space between the plus/minus symbol and the path entry
this is because duply uses the globbing exclude list duplicity feature, where an exclude list merely treats each entry with a default '-' if not defined otherwise. see section 'File Selection' in the duplicity man page
