just a warning, should be fixed in later releases. see changelog

both are duplicity trying to restore owner and permissions of your 
files/folders. changing owner requires to be root, so it fails.

you mean in the listing below? probably for saving owner/perms for for the 
snapshot dir. did you backup '/' including '/home' excluding '**' ?

see above. for details check the fix. tldr; on registration backends sometimes 
import python packages that are only needed later, if the backend was selected. 
a typical oversight in new or modified backends. non-critical in case you 
didn't use the complaining backend.
