"""
Copies all keys from the source Redis host to the destination Redis host.
Useful to migrate Redis instances where commands like SLAVEOF and MIGRATE are
restricted (e.g. on Amazon ElastiCache).

The script scans through the keyspace of the given database number and uses
a pipeline of DUMP and RESTORE commands to migrate the keys.

Requires Redis 2.8.0 or higher.

Notes of Scale Summit 2015 what's changed since last year.

Things last year:
- “Big Data is a thing”; Big Data is now pointless
- “Is CouchDB dead?” npm were? Fairly sure couchdb is now dead, despite more funding
- Under still going: Mongo, Riak. Mongo's not dead? Guardian, GDS, MOJ. Mongo on the rise again? Mongo *might* be dead; we don't know.
- Websockets were "standard" but weren't really… except for certain browsers, proxies, etc.
- HTML5 video still doesn't really work
- Flash is still dying… Unless you count CVEs. Lots of flash-based ads.
- WebGL has taken hold? Still true, apparently.

Simple, semi-anonymous backups with S3 and curl

Backing stuff up is a bit of a hassle, to set up and to maintain. While full-blown backup suites such as duplicity or CrashPlan will do all kinds of clever things for you (and I'd recommend either for more complex setups), sometimes you just want to put that daily database dump somewhere off-site and be done with it. This is what I've done, with an Amazon S3 bucket and curl. Hold onto your hats, there's some Bucket Policy acrobatics ahead.

There's also a tl;dr at the very end if you just want the delicious copy-pasta.
