    # NextCloud to Amazon S3 Backup Script
    # Author: Autoize (autoize.com)

    # This script creates an incremental backup of your NextCloud instance to Amazon S3.
    # Amazon S3 is a highly redundant block storage service with versioning and lifecycle management features.

    # Requirements
    # - Amazon AWS Account and IAM User with AmazonS3FullAccess privilege
    # - Python 2.x and Python PIP - sudo apt-get install python && wget https://bootstrap.pypa.io/get-pip.py && sudo python get-pip.py
    # - s3cmd installed from PyPI - sudo pip install s3cmd

    # Name of Amazon S3 Bucket
    s3_bucket='s3_bucket_name'

    # Path to NextCloud installation
    nextcloud_dir='/var/www/nextcloud'

    # Path to NextCloud data directory
    data_dir='/media/external/CloudDATA'

    # MySQL/MariaDB Database credentials
    db_host='localhost'
    db_user='nextclouduser'
    db_pass='secret'
    db_name='nextcloud'

    # Check if running as root

    if [ "$(id -u)" != "0" ]; then
    echo "This script must be run as root" 1>&2
    exit 1
    fi

    echo 'Started'
    date +'%a %b %e %H:%M:%S %Z %Y'

    # Put NextCloud into maintenance mode.
    # This ensures consistency between the database and data directory.

    sudo -u www-data php $nextcloud_dir/occ maintenance:mode --on

    # Dump database and backup to S3

    mysqldump --single-transaction -h$db_host -u$db_user -p$db_pass $db_name > nextcloud.sql
    s3cmd put nextcloud.sql s3://$s3_bucket/NextCloudDB/nextcloud.sql
    rm nextcloud.sql

    # Sync data to S3 in place, then disable maintenance mode
    # NextCloud will be unavailable during the sync. This will take a while if you added much data since your last backup.

    # If upload cache is in the default subdirectory, under each user's folder (Default)
    s3cmd sync --recursive --preserve --exclude '*/cache/*' $data_dir s3://$s3_bucket/

    # If upload cache for all users is stored directly as an immediate subdirectory of the data directory
    # s3cmd sync --recursive --preserve --exclude 'cache/*' $data_dir s3://$s3_bucket/

    sudo -u www-data php $nextcloud_dir/occ maintenance:mode --off

    date +'%a %b %e %H:%M:%S %Z %Y'
    echo 'Finished'
