Backups are hilarious. Everybody talks about them and nobody does them. Everybody loses ALL THEIR SHIT and screams and cries and screams again. Humans are funny.

For personal use the answer is pretty easy:

1. Buy a Mac
2. Buy an external USB drive - a simple teeny one that has more capacity than your hard drive and does NOT require a separate power cord
4. Set up Time Machine, which comes with your Mac
5. Keep hooking that drive up for a while every day
6. That's it. Time Machine backs up automatically, you don't have to think about it. As a bonus you can get back to versions of any file as of particular dates. But the main win is that you can restore your entire machine if you must replace your drive or your entire computer.

Sure, the external drive could fail, but your main drive and your external drive aren't going to fail on the same day. It's more than good enough. And it is BETTER than your fancy backup solution that is complicated that you never use.

The only backup that matters is a backup that you actually use.

For professional use it's a little trickier. At work we've come to favor using Amazon S3 for backup of client projects.

For a while we had a Drobo. It was shiny, but too shiny. It is shininess tempted folks to try to set it up as a network Time Machine time capsule... thing... which never worked. Eventually we just bought people individual external drives: simpler is better.

Then we hooked it up in the basement to back up certain projects nigthly. That was better, and it was sweet that it could handle a failed drive so gracefully... until it started to get really really slow and we realized it was old and unsupported and scary to rely on.

We also tried a bargain-basement RAID setup, with two external drives. This was not good. Linux kept changing its mind about what to call the array and the individual drives, no matter how much I worked to lock those things down. It shouldn't be hard to figure out which drive is the dead one.

So we moved to Amazon S3. It's awesome: it's not in your basement, it's geographically redundant (data centers in widely separated states), it's highly redundant on the local level too, and you don't worry about ANY of that shit. You just pay the bill.

Amazon S3 is shiny and you can do fancy things with it, but we try to keep it as stupid as possible: we use a simple command line tool called s3cmd to move things to and from S3. We make an archive file of an entire project and upload that to S3; we keep three weeks of those archives. It's too simple to screw up.

OK, we did do one fancy thing with S3: I wrote a nice nodejs-powered tool to manage the backups.

You can pick up the code here on github. It's nifty, but it has one flaw: it downloads each project locally, archives it, and uploads the archive, then proceeds to the next project. And this takes a long time. So since we have a lot of clients with big projects, we can only do weekly backups, not daily.

So the next generation of this tool will probably do all the work for each project on the server that hosts that project, allowing them all to back up to S3 in parallel. Which means setting up a separate S3 "bucket" for each project, for security reasons. And... other stuff. So for now, we stick with the simple version.

So I launched a "friendstarter," asking for 20 real life actual pals to commit to going back on the air on LiveJournal. Ironically I did this on Facebook, because that is where everybody is, and has been for some time now.

It looks like it's happening.

So I'm opening up all the disused rooms in my LJ and throwing out the stuff that was abandoned there years ago.

Remember when it was tacky to unfriend anybody on LJ and people wound up setting up filters for who they REALLY read and... yeah, we're all grownups now and most of us aren't even here. So I'm going through my nine friggin' pages of friends and pruning out anybody I honestly just don't remember anymore. In the hopes that my actual feed, rather than my special "mustread" feed, will be something I can really consider grappling with.

I'm pretty excited about this. I'm a little amazed to be excited about having to use the godawful joke of a mobile interface that LJ offers... or rather, to just have to wait until I'm at a proper lappy, which is probably healthier anyway. But apart from that, excited.
