Where is the address book kept?

[nickh]

I’ve just discovered the joys of the NC Address book and Thunderbird for my wife and I with 2 laptops and 2 static PC’s. I’d like to be able back it up, if at all possible but I don’t see a file for it. Is it kept in the database? If so, is there an easy way to dump it?

Using the search function of this forum, I found this:

Calcardbackup: bash script to backup Nextcloud calendars and addressbooks as *.ics/*.vcf files

I just released version 0.2.0 of the script, which comes with a new option to include shared addressbooks/calendars to the backup. This may be used to provide only one username + password in the credentials-file to whom all addressbooks/calendars (to be backed up) are shared. A just for this purpose created new user would make sense. If the file gets somehow in wrong hands, only the credentials of this single user will be compromised. Drawback of this approach is: added addressbooks/calendars …

Thanks. I tried a search via google for the storage location, but failed to get anything.
