-- The scripts only backup the Nextcloud data directory. If you have any external storage mounted in Nextcloud, these directories have to be handled separately.
-- If you have enabled 4 byte support (see [Nextcloud Administration Manual](https://docs.nextcloud.com/server/14/admin_manual/configuration_database/mysql_4byte_support.html)) while backup, you have to enable 4 byte support on the target system *before* restoring the backup.
-- If you do not want to save the database password in the scripts, remove the variable *dbPassword* and call *mysql* with the *-p* parameter (without password). When calling the scripts manually, you'll be asked for the database password.
+- 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/15/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.
