]]> Comment on Testing your database backups: the test environment database refresh pattern by graham http://devblog.songkick.com/2013/03/20/testing-your-database-backups-the-test-environment-database-refresh-pattern/#comment-72907 graham Wed, 20 Mar 2013 19:38:15 +0000 http://www.songkick.com/devblog/?p=4116#comment-72907 Completely agree, backups are a last resort for production recoveries. Replication is our first line. I still feel better for knowing that our last line of defence is tested though.

The lag slaves isn’t something I’ve done, but definitely worth looking at. Is it something that you’ve used for test environment refreshes?

I think filesystem vs. logical dumps is a speed vs. convenience tradeoff. On MySQL, our dataset is larger and xtrabackup deals with untangling the master/slave replication details from the backup, so we use filesystem + logs.

Our MongoDB dataset is tiny and dumping and restoring takes a few minutes; it was actually quicker than restoring snapshots for us. Plus it avoids any complexity around restoring into a replica set in staging.

– lag slaves
– slaves
– filesystem backups
– logical backups / dumps

Nobody wants to be that guy restoring a nightly backup 23 hours after the last dump.

When making OAuth-based requests you need to take this into account and fail gracefully.

They could be in the database, the session, or somewhere else depending on the needs of your application.

First, they started with heart-to-heart conversations with their stakeholders about removing rarely-used features from the product. Those features were baggage, and once the product team saw what it was costing them to carry that baggage, they were persuaded to remove them. [...]

Do you always store the token an secret values in the database? Don’t they expire?
