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...

HOWTO Lightroom sync with s3 windows/macos

1. The pitch

As I am an avid photographer & travelling quite a lot, I wanted to sync my Adobe Lightroom library from Macbook to my Microsoft Windows desktop at home with very little/no human intervention. It is also a good thing that both Lightroom versions (mac & windows) share a common file system/structure, this helped alot in synchronizing data from one environment to another.

This HOWTO assumes you already have an AWS account created and running with an IAM user configured.

Put together, the solution would look as such (pardon my poor diagram skills):

                                  _  
macbook pro                     (`  ).                     windows desktop
