openhab-backup

Backs up openhab, influx databases, and pivccu configurations and syncs them to a cloud storage provider every 24 hours.

• openhab backup uses openhab-cli backup to create a backup including persistence
• influx backup uses influxd backup -portable to create a backup
• pivccu backup uses pivccu-backup to create a backup

Setup

1. Clone the repository to /opt/

2. Install rclone, a command line tool to manage files on cloud storage

3. Conigure rclone to sync backup files with your cloud storage provider of choice

4. Run the following command to modify /etc/fstab to mount /bkup as a virtual directory in memory to extend the lifetime of your SD card.

   echo "tmpfs /bkup tmpfs nosuid,nodev,noatime 0 0" | sudo tee -a /etc/fstab
   

5. Reboot the system with sudo reboot. If you do not want to reboot your system, you can alternatively apply the changes with the following call.

   sudo mount -a
   

6. Run sudo crontab -e and add one of the following options to create a cronjob that runs the backup once a day and pipes log output to a log file

   Backup all services

   0 0 * * * /opt/openhab-backup/sync.sh -a >> /var/log/openhab-backup.log  2>&1
