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?

At least in Ubuntu 16.04 it's not in ~/.config/dconf or ~/.gconf/apps/deja-dup/*, and for those searching for the dconf-editor you must look for SETTINGS EDITOR instead. It might be interesting for the ASKUbuntu Community to try to apply rules of OpenSource Community Philosophy, which means declare obsoleted or need to being confirm when a new version of Ubuntu is on. – JOduMonT Jul 17 '16 at 7:58

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

~/.gconf/apps/deja-dup/

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

UPDATE

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:

~/.config/dconf

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

Great answer, though caution: Opening the "Backups" app in Ubuntu and closing it again may cause some settings to revert. For example, using the dconf-editor I set backups to be kept at least 90 days (instead of the minimum available in the GUI app of 6 months). When I opened the app, it showed 90 days. But when I closed it and re-opened, it had reverted to 6 months. – DavidO Mar 9 '15 at 22:59

Instead of using dconf-editor, you can use gsettings from command line.

  • See all the options (keys) within the Deja-Dup schema, and their configurations: 

    gsettings list-recursively org.gnome.DejaDup

  • Edit keys:

    gsettings set SCHEMA [:PATH] KEY VALUE

    For example:

    gsettings set org.gnome.DejaDup include-list ['$HOME']

fwiw, added a dconf setting if you build this from source, it will create a volsize setting in org.gnome.DejaDup. you can change it to 500mb with dconf-editor.

patched source code for deja-dup

Amazing, the volume size of backup files is hardcoded! bazaar.launchpad.net/~peter-bsqt/deja-dup/volsize/revision/1‌​548/…. So the answer to the actual question is: No, there is no config option. – Jack Miller Oct 13 '15 at 12:38
