The opc command allows you to easily backup your instance's database.

Backing up

Run the following command:

opc inst -i {instance_ID} backup
 copy

Once your backup is complete, it will provide you with the path to where the backup is stored. By default, it will be contained within the following:

/opt/deskpro/data/instances/{instance_ID}/backups/
 copy

Restoring

Run the following command:

opc inst -i {instance_ID} restore -d /path/to/backup/
 copy

You will need to specify the path to the backup file.
