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:
- 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?
- Wuala does not store permissions properly. If you restore all permissions are gone.
- 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.
- 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.
