Check Installation and configuration

The following commands should execute without error or warning:

• duplicity --version
• duply --version
• gpg --version

Generate GPG Key

• run gpg --full-gen-key
• select default values but 4096 Bit
• select a password for the key
• copy the public key id to somewhere else for later use - it is a sring like 7A6E4278E2CAF3FA16240DADC94F3BEAB276F92D

Configure Duply

• create a profile: duply <profile_name> create
• edit config: nano .duply/<profile_name>/conf
  • enter your gpg public key it to GPG_KEY
  • enter the password to GPG_PW
  • enter the TARGET like a cloud space or something else
  • for SOURCE just enter / - details will be configured in an other file later
  • remove comment infront of GPG_OPTS and write GPG_OPTS='--pinentry-mode loopback'
• edit exclude file: nano .duply/<profile_name>/exclude

This is how you can add your Cygwin home folder and your Windows pictures folder to backup and ignore evenrything else - **

+ /cygdrive/c/Users/<your_username>/Pictures
- **
