Support google drive backend

[Tom Hughes]

It would be nice to be able to use Google Drive as a backup backend.

API: https://developers.google.com/drive/v1/reference/
SDK: https://developers.google.com/drive/downloads

Would the implementation of this proposal violate some terms of service of Google drive? If not I could implement this feature (Duplicity already support Google Docs).

[GothAck (gothack)]

I believe the Google TOS are quite open, and it's a published API for storing files within the space provided.

This would be especially helpful now that Ubuntu One support is stopping on June 1st.

Having a specific option for Google Drive/Docs in Déjá Dup would be nice but even better would be if Déjá Dup allowed the user to enter any arbitary backend that Duplicity *already* supports. For example, one should be able to enter any of Duplicity's supported URIs in Déjá Dup's "Custom Location" URI field. Unfortunately, this doesn't seem to work at the moment. If I try using Duplicity's URI for Google Drive with Déjá Dup's "Custom Location", I get an error "Backup failed - Location is not mountable."

Also, it seems that someone already created a branch with support for Google Drive. Would be great to see this merged.

I am definitely more interested in this now that Ubuntu One is shutting down. When I have more time, I'll look at this.

I truly believe that for almost all of Ubuntu users integration with U1 was the most important reason to use Déjà Dup. Ability to backup using free (as in beer) cloud services is something essential for an os-default backup application.

I know that the "Custom Location" field is hardcoded to pre-assume a gvfs URI. But is there anything that otherwise prevents using any URI supported by Duplicity, if code is changed to simply pass that on to Duplicity's command line?

Looks like this was disabled in http://bazaar.launchpad.net/~deja-dup-hackers/deja-dup/34/revision/1541 --- can this issue perhaps be reopened and linked to the corresponding duplicity bug that blocks it?

[Antti Ahti (apaatsio)]

What's the status of this? I can't get this to work (deja-dup 34.0)

I'm trying with Custom Location gdocs://username:<email address hidden>/Backup (with real username and password, of course). I'm getting "Location is not mountable" error when I try to do a backup.

[Michael Terry (mterry)]

This is close to finally being enabled. It will use credentials from GNOME Online Accounts. There are a few bugs in duplicity and gvfs that I'm waiting to have releases for. And then I'll uncomment the google drive support in deja dup.

I know it's been a long wait.

[Michael Terry (mterry)]

A quick update on this. Support has been enabled in git master. I've also made Google Drive the default backend for new users, as it is the most user-friendly cloud backend we support now.

This will be included with Deja Dup 37.x/38.0 (so you'll see it in Ubuntu 18.04 or similarly timed distros). Unfortunately duplicity 0.7.14 and the necessary gvfs fixes were released too late to get this into Deja Dup 36.0 (which will be in Ubuntu 17.10).

Released in 37.0
