Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

#!/bin/bash

if [ $# -ne 2 ]; then
    echo "Usage: $0 file partSizeInMb";
    exit 0;
fi

file=$1

if [ ! -f "$file" ]; then

# Automated AMI Backups
#
# @author Robert Kozora <bobby@kozora.me>
#
# This script will search for all instances having a tag with "Backup" or "backup"
# on it. As soon as we have the instances list, we loop through each instance
# and create an AMI of it. Also, it will look for a "Retention" tag key which
# will be used as a retention policy number in days. If there is no tag with
# that name, it will use a 7 days default value for each AMI.

## Using the mine data, we are trying to find the IP address of all servers 
## with roles: mod-cluster-node in the same environment as this minion.
##

 
# EXAMPLE A: THIS WORKS - but we are hard-coding the minion's environemt (development). We don't want to hard-code
{%- for server, addrs in salt['mine.get']('G@roles:mod-cluster-node and G@environment:development', 'network.ip_addrs', expr_form='compound').items() %}
# ... do stuff... 
{%- endfor %}
