Where are contacts, calendar info, etc.stored?

So I’m setting up some auto backups and (yes, I’m a newbie) it is asking for folders to include. That’s fine, but want to be sure it is including things like contacts, calendar entries, etc. and I don’t know where exactly these things are stored to make sure I am including all folders for backup? Obvious things like all me LibreOffice files are easy enough as they are all in one folder I created, but others that I mentioned, etc I don’t know where they are stored.

Here is a kind of brute-force way to find out: create a contact with a funny name that is likely to be unique, and make sure it is saved to disk. Then use grep to look for it in your home directory:

grep -r FunnyNameThatIsProbablyUnique

that might take a few minutes if you have lots of things in your home directory, but sooner or later the answer comes:

grep: .local/share/evolution/addressbook/system/contacts.db: binary file matches

So apparently contacts are stored there. For backup purposes, maybe you can simply include the whole ~/.local/ directory in the backup. Or ~/.local/share/ or something.


… an answer that you could have got here: https://source.puri.sm/Librem5/community-wiki/-/wikis/Tips%20&%20Tricks#contacts

albeit that that is on the phone and the OP may be asking about a laptop.

Some answers could be:

  • the entire disk - there are credible arguments for that choice but it would be difficult to do automatically
  • your entire home directory, plus any other user-created directories outside of that that contain worthwhile content, if any
  • maybe - if it is an option - excluding ~/.cache if explicitly including your entire home directory

The beauty of convergence and using the same software stack across devices is exactly that. Solutions for your phone can also work on your laptop and vice versa :smiley:


Totally agree - but there is one minor difference: the username is purism on the phone and whatever the user might have chosen on the laptop.
