backupator

Backupator is a backup system for systems using ZFS as storage. It uses ZFS snapshots to make the backups small and only take the space which was occupied after the last snapshot. It has a WebUI for easier management.

Requirements for the backup software

systemd linux distribution (currently tested with Ubuntu 20.04 LTS and CentOS 8)
MySQL client
MySQL database server
zfs
mbuffer

WEBUI Requirements

Apache 2.4 with mod_php
PHP 7.3 or newer
php7.4-mysql
mod rewrite enabled

Installation

./install.sh backupator # Install the backupator software on the storage server
./install.sh db         # Install the database structure
./install.sh www        # Install the web interface

Cleanup

./cleanup.sh backupator # Cleanup the backupator software in /opt/backupator
./cleanup.sh db         # Drop the database

To be fixed

Issues with the web UI -- Logging

Features to be addded

parallelisation of the backups

Monitor disk usage

To monitor the disk usage of the backupator storage node, the script /opt/backupator/bin/collect_disk_usage_stats.sh can be executed. It can be added to cron as follows:

27 * * * * /opt/backupator/bin/collect_disk_usage_stats.sh >/dev/null 2>&1

The script will populate the DB with the disk usage of all backed up datasets on the local backupator storage. This can be observed in the Storage Nodes and Clients pages in the Web UI.
