This repository contains two bash scripts for backup/restore of Nextcloud.
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).
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.
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.). All values which need to be customized are marked with TODO in the script's comments.
- The scripts assume that Nextcloud's data directory is not a subdirectory of the Nextcloud installation (file directory). The general recommendation is that the data directory should not be located somewhere in the web folder of your webserver (usually /var/www/), but in a different folder (e.g. /var/nextcloud_data). For more information, see here.
- However, if your data directory is located under the Nextcloud file directory, you'll have to change the scripts so that the data directory is not part of the backup/restore (otherwise, it would be copied twice).
- If you do not want to save the database password in the scripts, remove the variable dbPassword and call mysql with the -p parameter (without password). When calling the scripts manually, you'll be asked for the database password.
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.
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.
