When creating a backup the service container is `paused` but not `stopped`

We have to evaluate what that means for the sqlite database.
Can it happen that we backup the database in an unmerged state? (i.e. wal and shm file because the data was not merged yet)

I think as long as the complete data gets backed up the database should be fine, even if we copy it in an unmerged state, but we should evaluate if this is 100% safe.
