 # Bash script for creating backups of Nextcloud.
 #
-# Version 2.1.3
+# Version 2.3.0
+#
+# Requirements:
+#	- pigz (https://zlib.net/pigz/) for using backup compression. If not available, you can use another compression algorithm (e.g. gzip)
+#
+# Supported database systems:
+# 	- MySQL/MariaDB
+# 	- PostgreSQL
 #
 # Usage:
 # 	- With backup directory specified in the script:  ./NextcloudBackup.sh
 # 	- With backup directory specified by parameter: ./NextcloudBackup.sh <BackupDirectory> (e.g. ./NextcloudBackup.sh /media/hdd/nextcloud_backup)
 #
-# The script is based on an installation of Nextcloud using nginx and MariaDB, see https://decatec.de/home-server/nextcloud-auf-ubuntu-server-18-04-lts-mit-nginx-mariadb-php-lets-encrypt-redis-und-fail2ban/
