-# Nextcloud-Backup-Restore
+# Nextcloud-Backup-Restore
+
+This repository contains two bash scripts for backup/restore of [Nextcloud](https://nextcloud.com/).
+
+It is based on a Nextcloud installation using nginx and MariaDB (see the (German) tutorial [Nextcloud auf Ubuntu Server mit nginx, MariaDB, PHP, Let’s Encrypt, Redis und Fail2ban](https://decatec.de/home-server/nextcloud-auf-ubuntu-server-mit-nginx-mariadb-php-lets-encrypt-redis-und-fail2ban/)).
+
+## Usage
+
+**Important**
+
+After cloning or downloading the repository, you'll have to edit the scripts so that they represent your current Nextcloud installation (directories, users, etc.)
+
+## General information
+
+For a complete backup of any Nextcloud instance, you'll have to backup three items:
+- The Nextcloud file directory (usually */var/www/nextcloud*)
+- The data directory of Nextcloud (it's recommended to locate this not under the web root, so e.g. */var/nextcloud_data*)
+- The Nextcloud database
+
+The scripts take care of these three items to backup automatically.
+
+### Backup
+
+In oder to create a backup, simplly call the script *NextcloudBackup.sh* on your Nextcloud machine.
+This will create a direcotry with the current time stamp in your main backup directory (you already edited the script so that it fits yout Nextcloud installation, haven't you): As an example, this would be */mnt/Share/NextcloudBackups/20170910_132703*.
+
+### Restore
+
+For restore, just call *NextcloudRestore.sh*. This script expects one parameter which is the name of the backup to be restored. In our example, this would be *20170910_132703* (the time stamp of the backup created before). So the full command for a restore would be *./NextcloudRestore.sh 20170910_132703*.
