Incremental e-mail backups with Thunderbird

The Mozilla Thunderbird e-mail client doesn’t provide a back-up tool. It is possible though to use the search function to select only those e-mail messages that are more recent than your last back-up and save them, but this process doesn’t store the folder structure that your messages were in. This is only a working solution if you use only a few folders or none at all. I recently had to restore from a hard disk crash and spent half a day putting e-mails back in folders. (Another option would have been to keep my restored back-up in in its own folder; after all, it’s mostly old mail.)

Looking for back-up tools for Thunderbird, the official recommendation appears to be to get a program called MozBackup. The advantage of MozBackup is that it creates back-ups of profiles for several Mozilla tools, not just Thunderbird. Unfortunately it doesn’t do incremental back-ups.

Looking through’s support forums I encounter mostly disbelief that anybody would want to do incremental back-ups of e-mail messages and folders. As a web developer I often get sent large files by clients and designers. Lately this has decreased a lot—people store their files in the cloud and send me a link—but it still happens. Before the crash I had about 10 GB in e-mail on my hard disk.

There is a back-up plugin (I believe Mozilla uses the word add-on instead of plug-in) called ImportExport Tools which I think I used before to migrate from Pegasus to Thunderbird but which you can also use for back-ups. (Strangely the plug-in is stored under Miscellaneous at instead of Import/Export.) This contains an option for structured storage, that is to say, storing mails with their respective folders. Unfortunately this option won’t let you select the specific mails you want to export, it only works for all mail at once. It does have an automatic back-up setting which may or may not store the folder structure. I will update this posting once I find out more.

Note also that the author of the plug-in reports that storing folders is at the moment unstable, i.e. may not work.

Back-ups are dangerous if you don’t test whether or not you are able to restore them. As far as the ImportExport Tools plug-in is concerned I can report success in this regard. I created a second account in Thunderbird and imported the back-up of my primary account there. I only performed spot checks, I did not check if all mails were recovered.

Another option would be to store e-mail without attachments. That way I could easily store every mail I ever received on a single CD-R, which would make the whole incremental back-up thing just a little less important. Of course you’d have to find a way to store your attachments first. In case you are using your e-mail client as a sort of document management system this won’t work. Let’s say you receive lots of photos of loved ones via e-mail and then when you want to see these photos again later you view them in your mail client. In this example you never bothered to store your attachments in a separate location, so back-ups without attachments would be less of an option.

This week in racism

Here in the Netherlands we have a venerable, somewhat quaint but altogether rather innocent tradition involving a gift-giving immortal bishop called Saint Nicholas, who has a rather unfortunate side-kick called Black Peter.

Black Peter is unfortunate because of his appearance which has been closely modeled on certain racist caricatures of black people. He has black curly hair, big red lips and golden earrings, speaks with a broken accent and often plays the fool. Recently this side of our tradition has been causing a lot of friction, and this week we appear to be going through what I would like to call The Coming Out of the Racists.

  • When singer Simon Keizer asked people last week to donate money to help the typhoon victims in the Philippines, people responded with angry variants on “eigen volk eerst” (“our own people first”, a slogan popularised by 1970’s racist party Centrumpartij).
  • TV presenter Daphne Bunskoek made a ‘joke’ about what should happen to Black Peters returning to their country (black people go ‘home’ is another racist meme) by showing footage from the Steven Spielberg movie Amistad in which black slaves were whipped.
  • Holland’s Got Talent talent judge Gordon Heuckeroth thought it would be a good idea to address a Chinese contestant as if the latter were running a Chinese restaurant: “which one are you going to sing, number 39 with rice?”

Now Heukeroth, who seems to lack talent or sophistication along pretty much every axis you might care to investigate, has made a career out of insulting people. Together with singer Gerard Joling he made a TV series in which they kept bitching each other out, so maybe he was just being in character here.

On a more personal level, a black acquaintance went to an anti-Black Peter demonstration, and one of the first things happening to her was that somebody walked up to her and said “die, nigger” to her.


A quick iPad review

Apple iPad (iPad 2)

As it happens all the four things I don’t like about my Apple iPad manifested themselves within a few minutes of each other today and they also helped to highlight what a cool little device it is, so I figured it was time for a quick review.

The Apple iPad has replaced a great many items in my house, or it would have if I owned them. It has replaced the TV guide, a number of cookbooks, the weather report on TV, the laptop on the couch for looking up stuff on Wikipedia and so on. It has not replaced the laptop for viewing movies, simply because at 16 GB it has too little storage. (Maybe if I could stream stuff off a wireless media server, but I’ve too little need for such a beast.)

Maybe it would or would not replace a smart phone, but a smart phone only really comes into place when you have a need for an expensive subscription, which I don’t. I don’t even have a mobile phone subscription, and my land line subscription is increasingly becoming an artifact from olden times, like those 19th century irons people used to collect in the 1970s—I never call anybody and I use Skype when I do.

So there you have a limited lay-out of my private electronics needs.

The actual reason I own an iPad is for my business. I use it as device to test websites on and I use it as a note taking tool. I still use a paper notebook for important and private notes (less easy to hack and doesn’t break down as easily), but everything else goes onto the iPad and then Dropbox. I also use the iPad to carry my portfolio around. If I were a graphics artist it would probably be too small for this (although it might be a good back-up?).

If I didn’t already own one for my business, I’d get one (or something like it) for private use.

Which brings me to the irritants, one plus three.

The big downside of the Apple iPad (and presumably unique to this brand) is that it is very much what people call a ‘walled garden’. The device is a gateway to a store for software and media. It comes with a couple of relatively useful applications, but if you want anything more you have to head to the iTunes store. Apple makes very much sure that all software must be offered via their store. You may offer software for free, but as a developer you still have to jump through all of Apple’s hoops. One thing that makes it so your application won’t get through Apple’s vetting process is if your application allows other applications to bypass Apple’s vetting process. The result is that the free (as in free of cost) software ecosystem on the iPad isn’t nearly as rich as it could be. (For comparison, most of the software I use on my business PC is FOSS.)

For a cheapskate like me who doesn’t mind wasting hours of his time looking for free offerings this is still a problem but can be a minor one. For all normal people though, if you want the iPad for your home, consider getting a credit card first so that you can give Apple more money (they take a percentage off the top for apps sold through their store).

The three minor irritants:

  • The (rather expensive) power cable breaks down in no time (and the non-replaceable battery deteriorates pretty quickly, so you need that cable).
  • Apple backs up the contents of your iPad to one (and only one!) computer and if the hard disk of your computer crashes (as happened to me the other day) it will delete everything on your iPad the next time you try and synchronize it with that one PC!
  • The (also rather expensive and optional) cover develops a looseness over time. Since the cover doubles as an off-switch, this means you can drain your battery without noticing it (you’ll believe the iPad is sleeping when it’s not).

I won’t say the iPad (or tablets like it) are indispensable, but they are pretty nifty. They are as light and easy to handle as a not-too-heavy magazine and are exactly for that reason a drop-in replacement mostly for magazines (assuming you have Wifi and can get the content online).

I find note-taking to work very well once you’ve installed the right applications. I use MoApp’s myTexts Lite for texts and neuNotes for anything involving drawing. There are undoubtedly better note-taking apps, but the Lite version of myTexts already comes pretty close and in fact has some pretty nifty features which you would hope all note app producers would copy, such as a much improved keyboard.

Apple’s model is one of razors and blades, except that they charge a premium for both (because they can). One would hope they’d fix the minor irritants in later versions of the iPad, though from what I’ve seen so far they haven’t bothered.

This of course brings us to the following question. If you are not a web developer who simply needs the Apple iPad, would you buy something else?

(This is still a draft because I need to get back to work. I’ll iron out the typos later.)
