| # NextCloud to BackBlaze B2 Backup Script |
| # Author: Autoize (autoize.com) |
| # This script creates an incremental backup of your NextCloud instance at BackBlaze's off-site location. |
| # BackBlaze B2 is an object storage service that is much less expensive than using Amazon S3 for the same purpose, with similar versioning and lifecycle management features. |
| # Uploads are free, and storage costs only $0.005/GB/month compared to S3's $0.022/GB/month. |
| # Requirements |
| # - BackBlaze B2 account (10 GB Free) - Create one at https://www.backblaze.com/b2/sign-up.html |
| # - Python 3.x and Python PIP - sudo apt-get install python3 && wget https://bootstrap.pypa.io/get-pip.py && sudo python3 get-pip.py |
| # - BackBlaze B2 CLI installed from PyPI - sudo pip install b2 |
| # Instructions |
| # 1. Insert the following line in your NextCloud config.php file above the ); to move the cache above each user's data directory. |
| # If /media/external/CloudDATA is not your data directory, substitute the relevant directory before /cache. |
| # 'cache_path' => '/media/external/CloudDATA/cache', |
| # 2. Create a bucket and obtain your Account ID and Application Key from your B2 account. |
| # 3. Authenticate your CLI using the b2 authorize_account command. |
| # 4. Save this script to a safe directory such as /srv/backupToB2.sh and make it executable with the following command. |
| # sudo chmod +x backupToB2.sh |
| # 5. This script must be run as root. To run a backup now: |
| # sudo ./backupToB2.sh |
| # 6. Set up a cron job to run this backup on a predefined schedule (optional). |
| # sudo crontab -u root -e |
| # Add the following line to the crontab to conduct a weekly backup every Saturday at 2:00am. |
| # 0 2 * * sat root sh /srv/backupToB2.sh > /srv/backupToB2.log |
| # Save, quit and check that the crontab has been installed using the following command. |
| # sudo crontab -u root -l |
| # Name of BackBlaze B2 Bucket |
| b2_bucket='b2_bucket_name' |

| # Sync data to B2, 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 /media/external/CloudDATA is not your data directory, modify the --excludeRegex flag accordingly, which excludes the NC cache from getting synced to B2. |
