Installing and Configuring BOSH Backup and Restore
Page last updated:
This topic describes how to install BOSH Backup and Restore (BBR).
To install BBR, first validate that your jumpbox VM is a valid BOSH backup host,
then copy the
bbr executable to the jumpbox and configure BBR.
For more information, see Install and Configure BOSH Backup and Restore below.
After installing BBR, you can run
bbr commands to back up and restore your Tanzu Kubernetes Grid Integrated Edition
For more information about using BOSH Backup and Restore, see:
- To backup and restore Kubernetes clusters provisioned by TKGI, see Backing Up and Rrestoring TKGI Clusters.
- To backup and restore TKGI Management Plane Components, see Backing Up and Rrestoring TKGI Managmenent Plane.
Using BBR requires the following:
- A jumpbox.
A jumpbox is a separate, hardened server on your network that provides a controlled means of accessing the other VMs on your network. See the jumpbox-deployment GitHub repository for an example jumpbox deployment.
You must have a jumpbox before you can install BBR to the jumpbox.
The OpenBSD version of netcat must be installed on the jumpbox host.
bbrexecutable file. You must have the correct BBR executable version for your TKGI installation.
- To determine the correct version of BBR for your deployment, see the Tanzu Kubernetes Grid Integrated Edition Release Notes.
- To download a BBR installation file, see BOSH Backup and Restore on the VMware Tanzu Network.
Note: BBR does not support SSH gateways.
To install and configure BBR:
- Configure Your Jumpbox for BBR
- Install BBR on Your Jumpbox
- Verify Your BBR Installation
- Configure BBR Logging
Your jumpbox must meet or exceed minimum BBR requirements. You can use the Ops Manager VM as your jumpbox if it can be configured to meet all of the requirements below.
To configure your jumpbox to meet BBR requirements:
- Size the jumpbox to have sufficient storage space for your backups.
Ensure the jumpbox can communicate with the network containing your Tanzu Kubernetes Grid Integrated Edition deployment.
BBR uses SSH to orchestrate the backup of your Tanzu Kubernetes Grid Integrated Edition instances using port 22 by default.
Configure the jumpbox to be in the same network as the deployed VMs.
BBR connects to the deployed VMs at their private IP addresses.
Ensure there is minimal network latency between the jumpbox and the source VMs BBR backs up.
To install the
bbr executable to your jumpbox:
- Download the latest compatible BOSH Backup and Restore release from the VMware Tanzu Network.
To add executable permissions to the
bbrbinary file, run the following command:
chmod a+x bbr
To securely copy the
bbrbinary file to your jumpbox, run the following command:
scp LOCAL-PATH-TO-BBR/bbr JUMPBOX-USER@JUMPBOX-ADDRESS:
LOCAL-PATH-TO-BBRis the path to the
bbrbinary you downloaded from VMware Tanzu Network.
JUMPBOX-USERis the ssh username for connecting to the jumpbox.
JUMPBOX-ADDRESSis the IP address, or hostname, of the jumpbox.
To verify that BBR is installed:
Run the following command:
Verify the returned BBR version.
BBR writes backup and restore logs to the current directory in a file named
By default BBR writes errors associated with stack traces to the log file.
BBR also reports default information about the backup and restore run:
- The backup and restore scripts that it finds.
- When it starts or finishes a stage, such as
- When the process is complete.
- When any error occurs.
To troubleshoot a failed BBR run, enable verbose logging. When executed in verbose mode, BBR reports the following additional information:
- Logs about the API requests made to the BOSH server.
- All commands executed on remote instances.
- All commands executed on local environment.
- Standard in and standard out streams for the backup and restore scripts when they are executed.
To enable verbose logging, use the optional
