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 07:58

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 08:14

    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 09 '15 at 22:59
  • there is nothing there for me. I'm using Ubuntu 18.04 – Lost Crotchet Jun 24 '22 at 10:17

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']

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 03 '12 at 05:07
  • **Systems Settings >> Backup**, last tab: 'Schedule' – david6 Jun 03 '12 at 06:32
  • The settings are in file '~/.gconf/apps/deja-dup/%conf.xml', but that is only for experts. – david6 Jun 03 '12 at 06:34
  • So you cant change the volume size limit and the full backup time? – ECII Jun 03 '12 at 07:01

    These are more likely to be settings in scripts (for Duplicity) that are used by Déjà Dup. see: https://live.gnome.org/DejaDup/HowItWorks OR https://help.ubuntu.com/community/DuplicityBackupHowto (I would need to do more research to answer better.) – david6 Jun 03 '12 at 07:14
  • Hi just the question I was after. I did move most of my home to a new computer. I want to move my DejaDup settings to the new machine as well. So I copied the above mentioned ``~/.gconf/apps/deja-dup/%conf.xml`` from the old to the new machine. In my settings I had quite a few folders to ignore. But the settings don't show up on the new machine. I've checked on my onld machine and this %conf.xml file does not change when I change the DejaDup settings. Any thoughts? – seb Jun 04 '12 at 10:04
  • Check the directory, or copy all files (and sub-directories). There is more than one settings file. – david6 Jun 04 '12 at 10:55
  • yes there are more files. I've copied all of them but my settings are not 100% the same as on the old machine? – seb Jun 04 '12 at 12:34
  • Changed, in Answer. – david6 Jun 04 '12 at 12:40

    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

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! http://bazaar.launchpad.net/~peter-bsqt/deja-dup/volsize/revision/1548/libdeja/tools/duplicity/DuplicityJob.vala. So the answer to the actual question is: No, there is no config option. – Jack Miller Oct 13 '15 at 12:38
