Help with duply / Duplicity

edited December 2015 in Help


I am hoping someone here can help me.
I setup my server to backup few directories to S3 using Duply/Duplicity (with the help of few articles). The backup profile created via Duply is not using any encryption.

So the backup to S3 are working fine.

I am having trouble restoring these backups to a new server. On new server, I created the exact backup profile. (No encryption, exact same config)
But when I run
duply myprofile status
duply myprofile restore /var/ww

I am getting error like

`Start duply v1.6.0, time is 2015-12-27 16:41:05.

Sorry. A fatal ERROR occured:

duplicity missing. installed und available in path?

Which make no sense since duplicity is setup and working. What I am missing here??
Help please, I am having hard time with this.

PS. Both old and new server are running CentOS 6.7 (if that makes any difference)


  • Duplicity is missing

    yum -y install duplicity

    Hello Mark,
    I wouldn't be asking for help if it was that kind of issue. Duplicity is there, but Duply is just not getting it for some reason.

    I used This tutorial to setup backups ... (A big thanks to the Author)
    I didn't setup encryption on the main server so "GPG_KEY=Disabled"

    On I am trying to restore these backup over to a new server. Where I am failing.
    On new server the steps are simply like

    yum install duplicity duply gpg python-boto
    duply mybackupprofile create
    nano /etc/duply/mybackupprofile/config (made it exact copy of main server)
    nano /etc/duply/mybackupprofile/exclude (again .. exact copy)

    There is no pre or post file. Now I am trying to restore from backup and that is where I am having issue. The restore on the same server is working fine. It's just not working on new server.

    This is my 1st attempt with Duply/Duplicity or S3 ...
    Before you ask, S3 user have full access and not restricted as in the article.

    Thanks again.

  • Where is duplicity installed?

    If you manually run duplicity does it run or is it missing some prerequisite?

    [[email protected] ~]# whereis duplicity
    duplicity: /usr/bin/duplicity /etc/duplicity /usr/share/man/man1/duplicity.1.gz
    [[email protected] ~]# duplicity -V
    duplicity 0.6.22

    And running duplicity directly to list files from S3 bucket

    [[email protected] ~]# duplicity --no-encryption list-current-files s3://

  • Whats the name of the bucket you are restoring from?

  • @Umair try with "pip install dropbox2", because duplicity look for it.

  • ZEROF said: try with "pip install dropbox2", because duplicity look for it.

    This is not necessary unless you're using Dropbox.

    The issue is either a bad signature file, or bad bucket name.

  • @MarkTuner I agree with you, just he never said if he is using other modules or not.
