Backup to restic server

Applications

I have installed a Restic server on my Truenas Scale but cannot figure out how to use Deja Dup to backup to this Restic server. From the CLI Restic backup to Restic server works ok.
Is it at all possible to use Deja Dup as GUI for this?

Running Deja Dup on Fedora linux 43 KDFE plasma with Deja Dup installed via flatpak.

System Details:
OS=GNOME 49 (Flatpak runtime)
Desktop=KDE
Locale=C
Home=/home/pfbpe
Version=49.3 (flatpak)
Tool Name=restic
Tool Version=0.17.3

GSettings:
[org.gnome.DejaDup]
window-width=550
periodic-period=7
periodic-timestamp=‘2026-01-30T13:03:57.260476+01’
delete-after=0
last-run=‘2026-02-01T20:49:55.817921+01’
backend=‘remote’
window-height=460

[org.gnome.DejaDup.Remote]
folder=‘xaqf’
uri=‘rest://lde.aqp.t.g:mljwd’

[org.gnome.DejaDup.Google]
folder=‘nsqti-wbeciqv’

[org.gnome.DejaDup.Local]
folder=‘nsqti-wbeciqv’

That is a reasonable expectation, but we don’t currently support talking to Restic-server - just directly writing to a Restic repository.

The feature request for supporting a rest: url is here: Support for the rest:http[s]://url.path.com/ syntax for restic server repositories (#505) · Issues · World / Déjà Dup Backups · GitLab

As a workaround, you could use ssh or ftp or whatever to talk to the server filesystem directly.

Thank you for the quick reply, wish I asked sooner instead of trying to get it to work for hours.

What would the benefit be for using a Restic server?

Note to self: add an error message when trying to use rest: URLs so people know it’s just not yet supported not that they are doing something wrong.

As for your question, I’m not 100% on the advantages, but there might be an easier security story to tell if you’re only opening up Restic writes, not larger filesystem access.
