Is there any rational regarding application config files? Some rule that would allow to fill bugs for apps that do inconvenient things. Currently here is my situation: I am trying to do backup to start a clean Fedora 34 install.
For example, MuseScore has some configuration files in ~/.local/share/MuseScore/... but ~/.local/share/ is also where Gnome Boxes or VirtualMachine Manager or libVirt are storing their image, so the folder is about 30Go … I do not plan to backup that, I just copied my 3 XML files manually.
There are all kinds of “misbehaviors” like logs files in .config/VirtualBox/ or huge cache in .config/google-chrome/.
And the Home folder is also full of hidden files and folders.
Not mentioning that when you remove an application (via RPM or Flatpak) the config files stay in their hidden directory forever. On Android this kind of things are managed.
Does everybody carefully pick and choose the “relevant” folders and remove unused folders as the applications are removed? or do you just run huge and long backup?
I’m afraid this mainly depends on the apps and their developers.
If you want to raise an issue, each case should be treated separately.
So, the issues should be addressed to the respective upstream bug trackers.
On the other hand, the need to back up specific data is mostly personal preference.
You can save time and space by excluding some subjectively unimportant data.
The data may be stored in accordance with the standards, but it’s just irrelevant for you.
I am just trying to see what could be done globally. So that each user does not have to manage this mess.
I guess .config/ was meant to hold … configuration, but the message has been lost or never clearly stated or it is just my personal interpretation. I will start a crusade to make $HOME/.config/ THE configuration backup folder, free from logs, cache data or anything that is more than a few ko basically.
No doubt that issues should be raised for each application. Cache data is really not a matter of personal preference. But yes, at worse you will just lost time and disk space.
I was wondering the same thing. Back in the day I was happy that Déjà Dup was offering this great, convenient way to backup your data on Linux. Their default is to back up /home/$USER with the Trash excluded – seems legit.
But then you get shocked when realising that it would backup your Steam games along with 40 GB Windows boxes (minimum) on your precious cloud storage! Not even mentioning the time it’ll take for your files to get prepared.
I always considered /home to contain user-generated files only. But then again, isn’t a virtual machine image user generated? (;
Maybe opening a ticket at Déjà Dup might be more productive than a discussion here. Folks over there probably discussed this issue already.
Right now, I’m trying to configure an opt-in list for myself, and hoping I don’t forget anything important.
