Backup before upgrading
Make sure your system has enough free space to store the backup.
Stop the ThingsBoard Edge service to prevent data writes during the upgrade:
1
sudo systemctl stop tb-edge
Create the backup:
1
sudo -Hiu postgres pg_dump tb_edge > tb_edge.sql.bak
Verify the backup was created successfully:
1
ls -lh tb_edge.sql.bak
Restore the backup (if needed)
Stop the ThingsBoard Edge service (if it’s still running):
1
sudo systemctl stop tb-edge
To restore the PostgreSQL database from a backup file, run the following command:
1
sudo -u postgres psql tb_edge < tb_edge.sql.bak
Start the ThingsBoard Edge service:
1
sudo systemctl start tb-edge
