Hello Chandan,

Try this one here:

$ knife backup export -D /backup/chef/timestamp

To restore, knife backup restore

Hi All,

My Source and Target chef server version is 12.0.5 ("chef-server-core-12.0.5-1.el6.x86_64.rpm").

2 Scenarios:

First Scenorios

1) Setup target chef-server.
After setting up created user:

vagrant]# chef-server-ctl user-create takedump Test Test --filename test_chef.key

User is created.


Second Scenario:

1) I took dump from source chef-server. [I followed the below steps from link : https://docs.chef.io/server_backup_restore.html]

a) Make a postgres export using the following commands:

    export THEDATE=`date '+%Y-%m-%d-%H-%M-%S'`
    sudo -E -u opscode-pgsql bash
    /opt/opscode/embedded/bin/pg_dumpall -c | gzip --fast > /tmp/postgresql-dump-$THEDATE.gz
  

b) Synchronize to make sure that all of the data is present on-disk:

    sync

c) Backup the /etc/opscode and /var/opt/opscode directories and include the postgres export file as root

   

tar cvfzp var-opt-opscode-$THEDATE.tar.gz /etc/opscode /var/opt/opscode /tmp/postgresql-dump-$THEDATE.gz

2) Restoring on Target server: [setup target chef-server]

a) Stop the server:

    $ chef-server-ctl stop

b) Restore the previously backed-up files to the following locations:
        /etc/opscode
        /var/opt/opscode

    by using the following command, which will exclude PostgreSQL files:

   tar xvfzp /vagrant/var-opt-opscode-2015-06-19-08-23-26.tar.gz --exclude='var/opt/opscode/postgresql/9.2/data' -C /

c) Start the postgresql service:

    $ chef-server-ctl start postgresql

d) Restore the PostgreSQL database:

        su - opscode-pgsql
       
        gunzip -c /tmp/postgresql-dump-2015-06-19-08-23-26.gz | /opt/opscode/embedded/bin/psql -U "opscode-pgsql" -d postgres

        Ignore the following error messages:
            ERROR: current user cannot be dropped
            ERROR: role "opscode-pgsql" already exists

e) Start the server:

    $ chef-server-ctl start

Now when I try to login with the user which was existing on my Source chef-server, I am not able to login

When I try to create a new-user, see the beloww logs:

vagrant]# chef-server-ctl user-create takedump Test Test --filename test_chef.key
ERROR: Failed to authenticate to https://127.0.0.1:443 as pivotal with key /etc/opscode/pivotal.pem
Response:  An error occurred while trying to find  'pivotal'. Please contact support.
vagrant]# chef-server-ctl user-list
ERROR: Failed to authenticate to https://127.0.0.1:443 as pivotal with key /etc/opscode/pivotal.pem
Response:  An error occurred while trying to find  'pivotal'. Please contact support

Thanks,

Chandan
