Help with duply / Duplicity

Umair

Hello,

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
or
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?
PATH='/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin'
`

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)

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?

Whats the name of the bucket you are restoring from?

ZEROF

@Umair 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.
