Validating your new Deployment

This topic describes how to validate the health of your Concourse deployment before you perform a backup or upgrade.

Check your Instances for Errors

To check your instances for errors, do the following:

Run the bosh instances command to view the running, stopped, and errored processes deployed by your BOSH Director:
```
bosh -e BOSH-ENVIRONMENT-ALIAS -d TARGET-CONCOURSE-DEPLOYMENT instances --ps
```
Where:
- BOSH-ENVIRONMENT-ALIAS is your BOSH environment alias. If you do not have an environment alias, see Set up Certificates, Log in, and Alias your BOSH Environment in Installing Concourse with BOSH.
- TARGET-CONCOURSE-DEPLOYMENT is the name of your Concourse deployment.
If you see any red error statuses, fix these instances before you perform any backups or upgrade Concourse.

You can review tasks that have run recently to discover any operations that might have failed. To do so, do the following:

Run the bosh tasks command to view recent deployments to discover any errors that might have taken place recently:
```
bosh -e BOSH-ENVIRONMENT-ALIAS tasks --recent -d TARGET-CONCOURSE-DEPLOYMENT
```
If you see tasks with errors, investigate these before you perform any backups or upgrading Concourse.
