Deja-dup (now Ubuntu Backup) is just a GUI for duplicity, therefore it should store the config files somewhere. I would like to changed the backup volume size to something like 300MB and the increase the --full-if-older-than variable. is this possible?

This has changed in various Déjà Dup versions, but I believe it is currently at:


What can't you change using the GUI front-end?


from: launchpad.net: How do I also backup my deja Dup settings?

The settings used to be stored there, and the files are still present.

In more recent version they are stored in:

I'd like to increase the volume size and be more conservative with full backups (once every 6 months or so). I checked the location you mention but I cannot find where this parameters are kept. Any ideas? –  ECII Jun 3 '12 at 5:07
Systems Settings >> Backup, last tab: 'Schedule' –  david6 Jun 3 '12 at 6:32
The settings are in file '~/.gconf/apps/deja-dup/%conf.xml', but that is only for experts. –  david6 Jun 3 '12 at 6:34
These are more likely to be settings in scripts (for Duplicity) that are used by Déjà Dup. see: live.gnome.org/DejaDup/HowItWorks OR help.ubuntu.com/community/DuplicityBackupHowto (I would need to do more research to answer better.) –  david6 Jun 3 '12 at 7:14
The UI is inconvenient at best: it is very small and not resizable (12.04), and does not expose .* files/directories, many of which contain big caches or logs not needing to be backed up. –  FGM Dec 29 '14 at 10:12

The deja-dup settings can also be changed with dconf-editor in the dconf-tools apt package. The settings are in org.gnome.DejaDup.

+1 for best answer since Deja Dup / duplicity does not have its own config files anymore. Note: Schema org.gnome.DejaDup equals org > gnome > deja-dup in the dconf editor tree view :) –  user17254 Dec 16 '14 at 8:14
