I'm trying to backup to an external USB using Deja Dup. The backup appears to start ok but then I get the following "Access Denied" message:
Permission denied when trying to create ‘/run/media/rosco/e57c8d38-4a05-4b10-9eef-83ad18d4bd6b/duplicity-full.20140524T154308Z.vol1.difftar.gz’.
Can anyone please help?
