We use Backupninja to drive backups, mostly Duplicity against S3. Some things, like Postgres dumps, are custom commands that just upload individual files to S3.

We use Backupninja to drive backups, mostly Duplicity against S3. Some things, like Postgres dumps, are custom commands that just upload individual files to S3. The reason you want to wrap things in Backupninja is to centralize logging, scheduling and monitoring. Note that we only back up specific things like databases, logs (central syslog server) and data directories. We use Puppet to configure our boxes, and consider everything to be expendable that isn't data.
