 # Nextcloud Docker Scripts
 
-A collection of scripts to backup, upgrade and restore your docker nextcloud instances.
+I'd like to share my collection of scripts to back up, upgrade and restore Nextcloud Docker installations. They come 
+handy especially if you are managing multiple Nextcloud installations on your server.
 
-## To Do's 
+I am using the [Docker Homelab](https://github.com/cbirkenbeul/docker-homelab) for my Nextcloud instances.

-  - [x] no-logging-flag  
-  - [x] no-cleanup-flag

+**NOTE:**
+**This scripts will only work if you...**
+- have installed your Nextcloud within a Docker container
+- are using a container for the Nextcloud app and a separate container for the MySQL database  
+- are using a docker-compose file to bring up both containers
+
+**This scripts will only backup or restore the database and the config files of your Nextcloud installation!**
+
+## Usage
+
+### Install requirements
+```bash
+pip3 install -r requirements.txt
+```
+
+### Configuration
+1. Copy the `example_configuration.yml`.
+```bash
+cp example_configuration.yml configuration.yml
+```
+
+2. Adjust the `configuration.yml` with an editor of your choice.
+
+### Back up a Nextcloud installation
+
+The `backup.py` script will create a **backup of the database and the configuration** of your Nextcloud installations. 
+You can adjust the backup directory and the maximum number of backups in the `configuration.yml`.
+
+```bash
+python3 backup.py
+```
+or without user prompt
+```bash
+python3 backup.py cloud1 cloud2
+```
+
+### Restore a Nextcloud installation
+The `restor.py` script will **restore the database and the configuration** of your Nextcloud installations.
+
+```bash
+python3 restore.py
+```
+or without user prompt
+```bash
+python3 restore.py cloud1 cloud2
+```
+
+### Upgrade a Nextcloud installation
+The `upgrade.py` script will first back up and then try to upgrade your Nextcloud installations.
+
+```bash
+python3 upgrade.py
+```
+or without user prompt
+```bash
+python3 upgrade.py cloud1 cloud2
+```
+
+### Flags

+## Known issues
+- Sometimes the maintenance mode is not getting disabled properly after upgrades. 
+  A simple `docker exec --user www-data <app-cotainer> php occ maintenance:mode --off` does the trick.
