#
# Bash script for creating backups of Nextcloud.
#
-# Version 2.1.0
+# Version 2.3.2
+#
+# 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)
+# - 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/
