Wuala Backup and Symlinks

Posted January 10th, 2012 in web by Michael

Since I compared Dropbox and Wuala I did some further, in-depth investigation how Wuala works and if it really fits my needs. And while I still love the idea of the “Swiss bank” there are some drawbacks that you should be aware of if you want to use Wuala for backup purposes:

  1. Wuala does not backup Symlinks. It simply ignores them. So if you backup on a Linux or OSX System all Symlinks will be gone. I wonder why they do not simply store the original value of the symlink?
  2. Wuala does not store permissions properly. If you restore all permissions are gone.
  3. Wuala does not warn if the backup does not execute for a while. So if you leave it running in the background and there is some issue you won’t notice until it is too late.
  4. Wuala does not seem to use the OS events system but instead searches for changed files “manually”. This makes it slower and uses more resourced than needed (compared to i.e. Dropbox). File system notify tools exist for all platforms (i.e. here) and should be used for performance reasons.
While I could live with #3 and #4 and eventually even with #2, I really dislike the issue #1 – that symlinks are simply ignored. The Dropbox solution (include everything from the symlink) would also not work for a real-world backup… and I really wonder why Wuala says it is a “backup solution” if it cannot handle simple symlinks.

Goodbye, Delicious!

Posted December 29th, 2011 in web by Michael

Since AVOS took over Delicious from Yahoo earlier this year things did not get better… The browser integration stopped working (I consider signing in every time I want to bookmark something as “not working”!) and the site has serious performance problems… I do not want to wait 3-5 seconds for storing a simple bookmark.

Thus it was finally time to look for alternatives, and I found it in the form of “pinboard.in“, a social bookmarking service without all the social crap:

Pinboard is a bookmarking website for introverted people in a hurry.
The focus of the site is less on socializing, and more on speed and utility.

And that describes it very well – it is fast, defaults to private bookmarks, has browser extensions available that work and it has the same API as Delicious – so rewriting scripts is a matter of changing the host name.

The drawback? They charge the *incredible* amount about $10 once, to board the service </sarcasm>.

So, if you want a fast, flawless and working bookmarking service check out Pinboard.in, but be prepared to support the developer with your credit card. You won’t regret it.

(Thanks Klaus for the tip!)

Stuxnet Report

Posted October 29th, 2011 in web by Michael

When I recently stumbled across the (already old) Stuxnet article on Wired I was just amazed. This article describes how the Stuxnet worm was discovered and disassembled, the target it tried to attack and it shows how advanced this work is. The article reads like a novel from Dan Brown and I highly recommend it to anyone interested in the latest news about the cyberwar….

Dropbox vs. Wuala

Posted October 28th, 2011 in web by Michael

Recently Apple replaced MobileMe with iCloud but they did not include a replacement for iDisk, the “remote disk” part of MobileMe. So it is time to search for something new and to rethink the external backup strategy for offsite backups…. The obvious replacement would be Dropbox, but with the recent security issues they had I was also looking for alternatives. It turned out most alternatives are really not as good as Dropbox, but Wuala got my attention… and so here it is, the Dropbox vs. Wuala comparison….

Supported operating systems and sharing

Both Dropbox and Wuala support OSX, Linux and Windows and are available on a wide range of mobile devices. On Dropbox the data can also be viewed through the Website, Wuala requires the Java plugin to be available (see below for the reason). Both systems allow to share files with other users and send out links to any user, so they can be used for sharing large files.

Security

The Dropbox folder integration

SSL is the standard for communicating with the servers, but the major difference between the services is that Wuala encrypts the files locally before sending them to the servers. This means that even Wuala cannot read your data as the password never leaves your system. However the drawback of the increased security is that files cannot be viewed easily through a Web interface and the Java plugin is needed to access the files using a Web browser.

Personally I think the security and privacy model of Wuala is far more advanced than the one of Dropbox, where employees of the provider can access the data (and even specify this right in the terms of use). Wuala feels more like a private, personal safe that no-one has access too, and this picture gets even stronger if you think about the fact that they are located in Switzerland and not in the US.

User interface and ease of use

Dropbox is super-simple and very well integrated into the Finder/Browser of the OS, Wuala on the other hand is very old-school. That is actually the reason why Dropbox is so popular, it is a no-worry solution. There is one folder that syncs, the icons on this folder show the status (uploading/up-to-date) and that’s it. No configuration, no scary dialogs, simple and effective.

Within the Wuala application the user is confused with too much information and it takes a while to get used to it. So there is room for user errors in the Wuala client, but on the other hand it offers more flexibility. For example it allows read-only backups and multiple sync-folders. However – it is more satisfying for tech users who want to control and configure stuff – but it completely misses ease-of-use, that makes applications popular these days.

Performance & Tools integration

Performanc-wise it seems that Dropbox is faster than Wuala, one reason being that they do not transmit the full file but only the changed parts (a feature that Wuala will have pretty soon). To say it with different words: Dropbox is amazingly fast. It just works and syncs super fast. Will be interesting to see how Wuala performs once they enable partial file transfers as well.

Also a plus on the Dropbox side is the integration with other tools. By opening and documenting the API and giving other apps access to the data there are text editors, mobile apps, password managers etc. that all store their data on Dropbox. Wuala (based on its security model) does not offer that kind of integration.

What both services handle very differently (and not very well) are symlinks. While Dropbox uses them to sync folders that are not within the /Dropbox folder (challenging for backups that contain symlinks), Wuala simply ignores symlinks… both not ideal for a backup solution.

Price

The price of Wuala is (at the time of writing this) below the price for Dropbox ($129 vs. $199 for 100GB/year) and Wuala offers more choices and larger packages.

… and the winner is…

When I first started my investigation it seemed that I have two very similar services at hand… and indeed they share a lot of common features. But on a closer look Wuala seems to be more powerful when it comes to backup and syncing multiple folders. If Wuala would rewrite the OSX client to sit in the notification area and have Finder icon overlays like Dropbox I think it would be the perfect choice for keeping my files offsite. I also love the fact that they appear to be like a Swiss bank, with my data being my data, with them and no-one else having any access to it.

However Dropbox is so well integrated into other applications and it is really a “don’t make me think” application, so I need to keep the Dropbox client running for some of those apps (and the free 2GB version is good enough for that)….

IE6 Countdown

Posted March 7th, 2011 in web by Michael

Finally even Microsoft started working on phasing out Internet Explorer 6. They are pretty serious to drop the worldwide usage below 1%:

10 years ago a browser was born.
Its name was Internet Explorer 6.
Now that we’re in 2011, in an era of modern web standards, it’s time to say goodbye.

I love that initiative and hope the number drops pretty fast from 12% right now to 1%… would save us Web developers so much hassles… So go and upgrade or and check out http://www.ie6countdown.com/.

15 Jahre IPv6

Posted December 24th, 2010 in web by Michael

IPv6 wird dieser Tage 15 Jahre alt… Ja, ein Protokoll welches noch gar nicht wirklich verwendet wird…. und aufgrund seines Alters im aktuellen Internet einige Probleme haben wird.

Und so kommen auf die Internet-Nutzer einige sehr unschöne Erfahrungen zu. Damit sie dann trotz der Fehler von Herstellern und Betreibern ins Internet kommen, müssen sie viel mehr über IPv6 lernen, als sie je wissen sollten. Denn schließlich handelt es sich um ein Protokoll einer recht tiefen Netzwerkebene, also ein technisches Detail. Wer das Internet benutzt, sollte darüber eigentlich gar nichts wissen müssen.

Dem kann ich nur zustimmen… es wird sich aber leider nicht vermeiden lassen… die Umstellung wird der Horror!

Der ganze Geburtstagsartikel zu den kommenden Problemen mit IPv6 ist auf heise Netze zu finden.

Ich will euch mal sagen, wie das mit IPv6 laufen wird

Warum kommt mir das nur so bekannt vor?

… aber so blöde sind die Verantwortlichen nun nicht und es werden in *deren* Kreisen Meetings abgehalten. Die Zeit der Positionspapiere bricht an. Die sind fester Bestandteil der “cover-your-ass”-Strategie, die jeder Verantwortliche meisterlich beherrscht. Das ist deren Kompetenznachweis. Wir Admins haben root, die ihre Ruhe.

Absolut lesenswert! (via _m3)

Youtube wird 5!

Posted May 18th, 2010 in web by Michael

Wozu ich herzlich gratuliere! 2 Milliarden angesehene Videos PRO TAG sind wirklich nicht ohne!

Gespannt bin ich ja ob Google TV bzw. Youtube einmal Apple den Rang ablaufen werden. Deren Apple TV ist ja mehr ein Spielzeug und unterstützt nicht einmal Blue-Ray geschweige denn Aufnahmen auf Disk….

Was mich dabei aber doch schockt ist die folgende Aussage:

Der typische US- Fernsehzuschauer sitzt über fünf Stunden vor dem TV-Gerät. (Quelle)

Sport wäre glaube ich sinnvoller…

I’m going to delete all mail

Posted April 25th, 2010 in web by Michael

A great tip:

When you go on vacation, set up an autoreply that says, “I’m on vacation until x/x/2010. When I get back, I’m going to delete all the email that arrived while I was gone, so if this note is important, please send it to me again after that date.”

Something I’ll try next time I’ll go on vacation…

Bye-bye comment spam!

Posted March 17th, 2010 in web by Michael

Almost immediately after I migrated from Blogger to WordPress I started receiving comment spam. Not a lot, only 1 post every 1-2 days, but still annoying.

Luckily there are several solutions to fight Spam without the need for every user to register with the blog… and based on a recommendation from _m3 I installed the Akismet WordPress Plugin. What should I say, it works… Akismet is eating my spam and leaving through ham, works like a charm – thus highly recommended for WordPress installations!
