- # Bash script for restoring backups of Nextcloud.
- #
- # Version 1.0.0
- #
- # 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/
- #
- #
- # IMPORTANT
- # You have to customize this script (directories, users, etc.) for your actual environment.
- # All entries which need to be customized are tagged with "TODO".
- #
- #
- # Customisations by Draddy to fit with Docker install with this guide: https://forum.openmediavault.org/index.php/Thread/28216-How-To-Nextcloud-with-Letsencrypt-using-OMV-and-docker-compose/
- # all "(TODO)" should work if you don't change the composer file "TODO" still need your attantion
- #
- # If you try to migrate to another server, the best way would be to reinstall the setup as befor using your composer file
- # resetup it the same way (dbuser / password) and bring it up one time (login with admin) after that - run the script to get your settings, apps and userdata back.
