I'm using hamster-tracker on different machines, so, I want to share my data across these. How can I achieve, that hamster is using one single database, which is synced via ubuntu one?
You could add
~/.local/share/hamster-applet/ to your list of Cloud Folders syncing with Ubuntu One. You can do that by right-clicking on the folder > Ubuntu One > Syncronize This Folder.
Another option might be to move the
~/.local/share/hamster-applet/ folder into your
~/Ubuntu One folder and put a symlink at
~/.local/share/hamster-applet/ pointing to the folder in your Ubuntu One directory. You can easily make a Link by right-clicking and selecting Make Link.
NOTE: One thing you can not do is put a symlink in the Ubuntu One folder pointing at
~/.local/share/hamster-applet/. Ubuntu One will not follow a symlink.
