#
# Bash script for restoring backups of Nextcloud.
-# Usage:
+#
+# 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: ./NextcloudRestore.sh <BackupName> (e.g. ./NextcloudRestore.sh 20170910_132703)
# - With backup directory specified by parameter: ./NextcloudRestore.sh <BackupName> <BackupDirectory> (e.g. ./NextcloudRestore.sh 20170910_132703 /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/
