 # Bash script for restoring 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: ./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)
 #

 # Usage:
 #   - With backup directory specified in the script: ./NextcloudRestore.sh <BackupName> (e.g. ./NextcloudRestore.sh 20170910_132703)
