Duplicity

"UnsupportedBackendScheme: scheme not supported in url" when using rclone backend

Asked by Pope Rigby

I'm having an issue where I'm getting "UnsupportedBackendScheme: scheme not supported in url" when my Duplicity command is:

/usr/bin/duplicity full --encrypt-key $ENCRYPT_KEY$ --include-filelist /opt/backup/globbing_list / rclone://gdrive:/backup

I have rclone installed, and I have the gdrive remote setup (I can access it when I'm just using rclone) but I guess it can't identify rclone.

what is your duplicity version? maybe yours is too old. rclone was just added recently. check the Changelog http://duplicity.nongnu.org/vers8/CHANGELOG ..ede/duply.net

I'm on Debian so I have v0.7.18.2-1. I can't seem to find anything in the changelog that you linked about adding support for rclone.

check the Changelog link above. it just got added in 0.8 some weeks ago. here are the latest install hints from 0.8.12 release announcement

-->
There are a few download options:

    Release tarball Install - https://launchpad.net/duplicity/+download
    Daily duplicity builds - https://launchpad.net/~duplicity-team/+archive/ubuntu/daily-dev-trunk
    Stable snap builds - “sudo snap install duplicity —classic"
    Latest snap builds - “sudo snap install duplicity —classic —edge"
    Latest pip builds - "sudo pip install duplicity"

NOTE: UNinstall duplicity first if it was installed via the distribution repository. For Ubuntu, that would be "sudo apt-get purge duplicity".
