Bvckup and Bvckup2 sites have been moved to a new server. The update.bvckup.com has been moved to the same server as well. Should you notice any 404s, empty looking pages, strange messages or something equally amusing, do let me know.

A classification of data backups, and how conventional backups (do not) really fit in.

In the spirit of documenting changes that are obvious, but only in retrospect I want to go over a new versioning scheme that I am adopting for Bvckup. Its executive summary is -

No more dotted version numbers.

In other words, “Bvckup 2.1.3.14” becomes “Bvckup 2, revision 37” …or thereabouts.

Just a quick post to share something that seems obvious in retrospect, but took a while to notice and fix.

A mailing list for those wanting to follow Bvckup and Bvckup 2 progress has been up and active over a year now. Subscribing to the list triggers a typical confirmation email with a link that needs to be clicked on. The odd thing was that a good half of those subscribed never bothered to do that.

So last month, after receiving a small rush of sign-ups from betali.st I decided to put things in order and run a bit of A/B testing. Good thing I did.

Simply changing the email subject from this

to this

increased the number of completed subscriptions from 51% to 82%.

The original subject read like… well… a confirmation rather than something that requested an action and people simply did not bother even opening an email. A simple but costly oversight that took me almost two years to realize.

Comments

There is a thread for that:

Made it to BetaList yesterday and wow, just wow. Steady thick stream of traffic and trending up on their weekly list of populars too.

Thanks for the sign-ups, mentions and tweets, guys! Very much appreciated. And a big round of applause to Mr. Köhlbrugge for conceiving such a useful site.

I described several technical aspects of Bvckup 2 while it was on reddit.

As the development moves forward I will be posting detailed performance numbers for each listed feature, but meanwhile take a look at the overview to get a general feel for the amount of optimization finding its way into V2.

So here it is - A technical overview of Bvckup 2

Two-day sponsored post on reddit is now live - http://www.reddit.com/comments/iarao

About one quarter through and there is 2300 unique impressions so far, about 40 click-throughs, plus a bunch of opinions which is what I am after. All in all this seems to be beating Adwords hands down.
