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 20.04 LTS mit nginx, MariaDB, PHP, Let’s Encrypt, Redis und Fail2ban).
For a complete backup of any Nextcloud instance, you'll have to backup these items:
- The Nextcloud file directory (usually /var/www/nextcloud)
- The data directory of Nextcloud (it's recommended that this is not located in the web root, so e.g. /var/nextcloud_data)
- The Nextcloud database
- Maybe a local external storage mounted into Nextcloud
The scripts take care of these items to backup automatically.
- pigz (https://zlib.net/pigz/) when using backup compression. If not installed already, it can be installed with
apt install pigz(Debian/Ubuntu). If not available, you can use another compression algorithm (e.g. gzip)
Important notes about using the scripts
- After cloning or downloading the scripts, these need to be set up by running the script
- If you do not want to use the automated setup, you can also use the file
NextcloudBackupRestore.conf.sampleas a starting point. Just make sure to rename the file when you are done (
cp NextcloudBackupRestore.conf.sample NextcloudBackupRestore.conf)
- The configuration file
NextcloudBackupRestore.confhas to be located in the same directory as the scripts for backup/restore.
- 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 script configuration (file
setup.sh) so that the data directory is not part of the backup/restore (otherwise, it would be copied twice).
- The scripts only backup the Nextcloud data directory and can backup a local external storage mounted into Nextcloud. If you have any other external storage mounted in Nextcloud (e.g. FTP), these files have to be handled separately.
- The scripts support MariaDB/MySQL and PostgreSQL as database.
- You should have enabled 4 byte support (see Nextcloud Administration Manual) on your Nextcloud database. Otherwise, when you have not enabled 4 byte support, you have to edit the restore script, so that the database is not created with 4 byte support enabled (variable
- Clone the repository:
git clone https://codeberg.org/DecaTec/Nextcloud-Backup-Restore.git
- Set permissions:
chown -R root Nextcloud-Backup-Restore
chmod 700 *.sh
- Call the (interactive) script for automated setup (this will create a file
NextcloudBackupRestore.confcontaining the desired configuration):
- Important: Check this configuration file if everything was set up correctly (see TODO in the configuration files's comments)
- Start using the scripts: See sections Backup and Restore below
Keep in mind that the configuration file
NextcloudBackupRestore.conf hast to be located in the same directory as the scripts for backup/restore, otherwise the configuration will not be found.
In order to create a backup, simply call the script NextcloudBackup.sh on your Nextcloud machine. If this script is called without parameter, the backup is saved in a directory with the current time stamp in your main backup directory: As an example, this would be /media/hdd/nextcloud_backup/20170910_132703. The backup script can also be called with a parameter specifiying the main backup directory, e.g. ./NextcloudBackup.sh /media/hdd/nextcloud_backup. In this case, the directory specified will be used as main backup directory.
You can also call this script by cron. Example (at 2am every night, with log output):
0 2 * * * /path/to/scripts/Nextcloud-Backup-Restore/NextcloudBackup.sh > /path/to/logs/Nextcloud-Backup-$(date +\%Y\%m\%d\%H\%M\%S).log 2>&1
For restore, just call NextcloudRestore.sh. This script expects at least one parameter specifying the name of the backup to be restored. In our example, this would be 20170910_132703 (the time stamp of the backup created before). The full command for a restore would be ./NextcloudRestore.sh 20170910_132703. You can also specify the main backup directory with a second parameter, e.g. ./NextcloudRestore.sh 20170910_132703 /media/hdd/nextcloud_backup.
