ABOUT THIS SCRIPT

This bash script was designed to automate and simplify the remote backup process of duplicity on Amazon S3. After your script is configured, you can easily backup, restore, verify and clean (either via cron or manually) your data without having to remember lots of different command options and passphrases.

Most importantly, you can easily backup the script and your gpg key in a convenient passphrase-encrypted file. This comes in in handy if/when your machine ever does go belly up.

Latest version of the code is available at: http://github.com/thornomad/dt-s3-backup

BEFORE YOU START

This script requires user configuration. Instructions are in the file itself and should be self-explanatory. Be sure to replace all the foobar values with your real ones. Almost every value needs to be configured in someway.

You can use multiple copies of the script with different settings for different backup scenarios. It is designed to run as a cron job and will log information to a text file (including remote file sizes, if you have s3cmd installed). Be sure to make the script executable (chmod +x) before you hit the gas.
