A quick "how to" on what you need to do to both setup AND recover a single-server PostgreSQL database using WAL-E

• WAL-E: https://github.com/wal-e/wal-e
• Assuming Ubuntu 12.04 LTS ("Precise")
• We'll be using S3. Make sure you have an IAM in a group with GetObject, ListBucket and PutObject on the bucket you want to use (and that it's not public).

Setup:

1. These packages:

darkhelmet

// package spooler implements a disk-persistent queue.
//
// Spooler uses MDB (LMDB) to implement a queue of byteslices. Its intended usecase
// is to enqueue work items received by a service before later working them off.
// Note that Spooler only flushes to disk up to once every 25ms. As a result,
// if the process or machine crashes unexpectedly, the most recent 25ms of work
// can be lost. This decision effectively increases throughput by 10,000%,
// but makes spooler unsuitable for jobs that absolutely cannot be allowed to fail
// under any circumstances.
package spooler

Day job: Polyglot senior developer primarily doing ruby/rails.

Favorite Python project: Probably mercurial, even though I am a git user at heart. Flask is also fantastic.

Favorite Conference: I don't have any conferences under my belt yet :(

Python Experience Level: Just out of the beginner phase into amateur or weekend warrior. Let me get my battle axe...
