 This repository contains two bash scripts for backup/restore of [Nextcloud](https://nextcloud.com/).
 
-It is based on a Nextcloud installation using nginx and MariaDB (see the (German) tutorial [Nextcloud auf Ubuntu Server 18.04 LTS mit nginx, MariaDB, PHP, Let’s Encrypt, Redis und Fail2ban](https://decatec.de/home-server/nextcloud-auf-ubuntu-server-18-04-lts-mit-nginx-mariadb-php-lets-encrypt-redis-und-fail2ban/)).

 ## General information
 
@@ -20,8 +20,8 @@ The scripts take care of these items to backup automatically.
 - The scripts assume that Nextcloud's data directory is *not* a subdirectory of the Nextcloud installation (file directory). The general recommendation is that the data directory should not be located somewhere in the web folder of your webserver (usually */var/www/*), but in a different folder (e.g. */var/nextcloud_data*). For more information, see [here](https://docs.nextcloud.com/server/latest/admin_manual/installation/installation_wizard.html#data-directory-location-label).
 - However, if your data directory *is* located under the Nextcloud file directory, you'll have to change the scripts so that the data directory is not part of the backup/restore (otherwise, it would be copied twice).
 - The scripts only backup the Nextcloud data directory and can backup a local external storage mounted into Nextcloud. If you have any other external storage mounted in Nextcloud (e.g. FTP), these files have to be handled separately.
-- The scripts assume that you are using MySQL/MariaDB as database for Nextcloud. However, it also supports PostreSQL databases. In this case you have to uncomment the parts of backing up/restoring the database.
-- You should have enabled 4 byte support (see [Nextcloud Administration Manual](https://docs.nextcloud.com/server/latest/admin_manual/configuration_database/mysql_4byte_support.html)) on your Nextcloud database. Otherwise, when you have *not* enabled 4 byte support, you have to edit the restore script, so that the database is not created with 4 byte support enabled.
+- The scripts support MariaDB/MySQL and PostgreSQL as database.
+- You should have enabled 4 byte support (see [Nextcloud Administration Manual](https://docs.nextcloud.com/server/latest/admin_manual/configuration_database/mysql_4byte_support.html)) on your Nextcloud database. Otherwise, when you have *not* enabled 4 byte support, you have to edit the restore script, so that the database is not created with 4 byte support enabled (variable `dbNoMultibyte`).
