# Bash script for restoring backups of Nextcloud.
|
|
# 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/
|

|

# You have to customize this script (directories, users, etc.) for your actual environment.
|
|
# All entries which need to be customized are tagged with "TODO".
