Setup automatic backups and email alerts with Duplicity and Logwatch With Ubuntu 12.04

I am using Duplicity to automate off-site backups. What I wasn't doing before - checking integrity of remote backup. Due nature of backing up to remote location, it quite possible to have issues like half uploaded files, corrupted files, missing files, etc. I wanted to have something in place to check backup right after backup procedure is finished and email me if there are any differences.

Simple backup solution with backup-manager and Amazon S3

After the disaster with the Ukraine hosting data center I started thinking about backup options for my own dedicated server that I use to host and dozens of my other projects and a few clients' sites. So far it has been a plain backup on the second drive, but this accident showed that even having a hosting company do backups in the same building is not really a safe solution.
